MCOR / Pedal Assembly Confusion Explained
 

It seems that every single day I'm getting numerous emails and private messages about this very topic so I'm going to post a new thread and explain it all. Hopefully this helps you guys out. :thumbup:

---------------------------------------------------------

MCOR MODELS

MCOR1 - Part Number 102101101 - This was the DS MCOR found on all DS models since the introduction of the MCOR in 2001 until the MCOR3 came out in 2012. It is now an obsolete part number and is no longer manufactured. If you need to replace one of these you must order a conversion kit.

MCOR2 - Part Number 102528501 - The original Precedent MCOR. It is exactly the same as the MCOR1 internally. Externally, it mounts differently and has a different input shaft. It will only work on Precedent models. Will not fit on anything else.

MCOR3 - Part Number 103850401 - Obsolete, Replaced with MCOR4. If your vehicle is equipped with one of these, an MCOR4 will work as a direct replacement.

MCOR4 - Part Number 105116301 - The newest version of the MCOR. Works on both DS and Precedent models. However, if the vehicle isn't currently equipped with an MCOR3 or MCOR4, you must order a conversion kit to make it fit. Details Below

---------------------------------------------------------

PEDAL ASSEMBLY (Precedent Only)

There are two different styles of pedal assemblies for Precedents. I've attached a photo of both to help identify which one you have.

Generation 1 Pedal Assembly - Uses MCOR2 only. MCOR3 and MCOR4 will not fit. Period.

Generation 2 Pedal Assembly - Can be used with MCOR2, MCOR3, or MCOR4. If you currently have an MCOR2 that needs to be replaced, you have the option of replacing it with another MCOR2 or ordering the MCOR4 conversion kit. Either way works.

---------------------------------------------------------

MCOR CONVERSION KITS

MCOR2 to MCOR4 Conversion Kit for Precedent with Gen2 Pedal Assy - AM293001

MCOR1 to MCOR4 Conversion for DS - AM293101

V-Glide or Potbox to MCOR4 Conversion for DS - AM293201

---------------------------------------------------------

Notes: If you have a 2009 Precedent, read this. If not, it doesn't apply.

In 2009 Club Car attempted to eliminate the MCOR2 and used a Throttle Position Sensor (TPS). It didn't work out and production stopped by 2010. 2009 Vehicles were supposed to all be swapped back to an MCOR2. This was a warranty repair. However, I've seen lots of 2009 vehicles still equipped with the TPS. If you have it, convert it. It's going to cause you trouble down the road.

2009 Vehicles that were converted from a TPS to an MCOR2 will have a small adapter (PHOTO ATTACHED) plugged into the MCOR. In IQ models, it's simply a plug designed to convert the 6 pin TPS connector to the classic style MCOR2 plugs. In Excel models, this adapter has three 461ohm resistors inside soldered into the three throttle wires. This adapter MUST BE in place or the Excel vehicle will not function properly. In 2008 and 2010-Present the resistors are soldered into the main wire harness and the adapter is not necessary.

Nice info. Sticky this ish

Re: MCOR / Pedal Assembly Confusion Explained
 

Good info

Re: MCOR / Pedal Assembly Confusion Explained
 

I fall into the 2009 CC Precedent IQ category and was totally lost with all the issues and questions concerning my MCOR replacement. I also had no idea about the TPS situation. Thank you for your detailed explanation.

Re: MCOR / Pedal Assembly Confusion Explained
 

I see some AM293201kits that include a metal rod. Seems some do not. What is the rod for?

Re: MCOR / Pedal Assembly Confusion Explained
 

It's the drive bar. It attaches to the accel pedal and the other end goes into the MCOR4 to make it rotate as you apply throttle.

Re: MCOR / Pedal Assembly Confusion Explained
 

I have the pedal group 1, it seems only I can replace it with the same MCOR which is 2, is the newer version 4 any better than the original 2?

Re: MCOR / Pedal Assembly Confusion Explained
 

No. It's definitely not better. Nor can I confirm that it's worse.

Re: MCOR / Pedal Assembly Confusion Explained
 

Thanks David, looks like I'll need a new one soon, last time at the camp it was getting jerky.

Re: MCOR / Pedal Assembly Confusion Explained
 

With TahoeDawgZ71 detailed information I ordered and installed my MCOR4 in 15 minutes. It now runs smooth with no low or high speed jerking. Also resolved what I could only describe as pedal stiffness. Maybe I was just trying to push the pedal too hard because of the jerking. Runs like new....:thumbup:

Re: MCOR / Pedal Assembly Confusion Explained
 

I have 2006 CC Prec with Gen 1 pedal assy. Question: will the Gen 2 assy physically fit as a replacement for Gen 1?

Re: MCOR / Pedal Assembly Confusion Explained
 

Yes. It's the only one they make now.

Re: MCOR / Pedal Assembly Confusion Explained
 

Tahoe Dawg....

I have the 2009 Club Car Precedent I2 Excel. It still had the TPS throttle in it when I upgraded to a 1268 controller. I was getting an accelerator code so my local dealer had an Mcor2 with adapter on hand. I replaced the TPS with the Mcor2 and got rid of the code. I'm still only getting 44% from the throttle and I think it's because the adapter I used does not have the resistors you spoke of in it. I am searching high and low for the correct adapter for the Excel cart, with the resistors. Do you have any idea what that part number is, or where I can find it?

Re: MCOR / Pedal Assembly Confusion Explained
 

Part number 103682701

Any club car dealer would be able to order it for you.

Re: MCOR / Pedal Assembly Confusion Explained
 

I saw that part number but was afraid of suggesting it, the description for the item says: Harness, Jumper, Mcor, Excel and IQ

If there are 2 versions of this adapter, one with resistors and one without, I could not tell by the description of the part #.

I saw that part number in both the 2009 & 2010 precedent IPL, no other part numbers are listed for the TPS to MCOR conversion in either catalog.

Is there a different part number for the adapter that goes into an IQ cart (supposedly without the resistors)?

Re: MCOR / Pedal Assembly Confusion Explained
 

There was a different adapter for the IQ car that didn't include any resistors, but I do not remember the part number. It's no longer available. The only one you can get is the one for Excel.

Re: MCOR / Pedal Assembly Confusion Explained
 

Tahoedawg, I've read a bunch if your posts but cant find one exactly like my issue. Today my precedent backed out of the garage just fine, started to move in forward then all of a sudden lurched then slowly rolled to a stop moving only about 12 feet. If I flip the run/tow switch a couple times then turn the cart on itll work for about 15 yards at very low speeds before it again comes to a stop. My 8 volt batteries all read 7 then at full charge the whole pack read 53. My lights, backup buzzer and the radio work just fine. I've tried to reset my OBC a couple times and it doesn't seem to help. One of the cart shops here thinks it is my mcor but I figured I'd ask you seeing you are able to fix so many peoples issues on this forum. Sorry for the long post. Thank you!

Re: MCOR / Pedal Assembly Confusion Explained
 

Tahoe and Sergio I'm sure could answer this much better than myself. But it sounds like you may be either having a problem with your solenoid or possibly the diode. Either way they'll probably need more info about your cart to help diagnose it better so go ahead and list your cart year, make, model and any mods to help out.

Re: MCOR / Pedal Assembly Confusion Explained
 

Hey thanks and I'm sorry I should have let everyone know I am actually working on this under a separate thread with Sergio

Re: MCOR / Pedal Assembly Confusion Explained
 

Sounds like the symptoms of a bad MCOR to me, Unplug the MCOR and jump the 2 pin connector with a paperclip and see if it works. Let me know what you find.

Re: MCOR / Pedal Assembly Confusion Explained
 

Tahoe Dawg thanks for the info on the am or and batteries I received the Mcor 4 with conversion kit and bought new batteries and now all is well thanks for all your insight and time on the phone

Re: MCOR / Pedal Assembly Confusion Explained
 

I had to purchase. Brand new pedal assembly and mcor4 I can't seem to line them up per instructions so the mcor clips to the pedal assembly. Any help would be appreciated.

Re: MCOR / Pedal Assembly Confusion Explained
 

I recently had to purchase an mcor4 and a new pedal assembly. I have seem to get them to line up so the mcor clicks into place on the pedal assembly. It looks like the mcor4 and the assembly both have male parts sticking out and preventing them from connecting.

Re: MCOR / Pedal Assembly Confusion Explained
 

Pull the male adapter out of the pedal assembly.

Re: MCOR / Pedal Assembly Confusion Explained
 

I have a 2007 Precedent with Gen 1 Pedal Assembly Am I correct I should purchase a
MCOR 2 ? Do I need an adapter?
When I lifted the Pedal Assembly therd was a bundle of unused leads .2 round 1 male 1 female quick connectt and 1 spade Female what are they for
Thanks Ken

Re: MCOR / Pedal Assembly Confusion Explained
 

All you need is the MCOR2. You don't need any adapters. The extra wires you see are for brake lights.

Re: MCOR / Pedal Assembly Confusion Explained
 

David Thank You

Where do I obtain a TPS converter like in pic 3?

Where do I obtain a TPS converter like in pic 3?

Re: MCOR / Pedal Assembly Confusion Explained
 

From our online store. Part number 103682701. Its in the MCOR and Throttle Section

Re: MCOR / Pedal Assembly Confusion Explained
 

David,

Thanks for this thread, very informative.

On the 2009 IQ models, where is that TPS to MCOR pigtail located, and how hard is it to get to? I'm wondering if mine has been converted.

Re: MCOR / Pedal Assembly Confusion Explained
 

It's plugged into the MCOR on one end. On the other end, the TPS connector from the original wire harness is plugged into the adapter module. It's usually found hanging loosely beneath the access cover under the floormat.

Re: MCOR / Pedal Assembly Confusion Explained
 

I suspect a new mcor is in my near future as the thing stutters when the accelerator is barely pushed. Works fine after half depressed and at full speed. I have a 2003 ds iq and, I suspect, the part number that you said is obsolete. Why is that so many retailers state they sell new replacement mcors for this part number but never mention the need for an adaptor...or am getting something wrong?

Do you sell the one that I need? How much?

Re: MCOR / Pedal Assembly Confusion Explained
 

Yes I sell it. It's on our web store.

The 102101101 DS MCOR is no longer made. If somebody is selling one, it's old inventory, plain and simple. They haven't made them in a few years now. The correct replacement part is AM293101 MCOR to MCOR4 conversion kit. It comes with a bracket, a drive bar, an adapter, some hardware, and a new MCOR4. Once you've bought the conversion one time you no longer need to buy it again. If the MCOR4 ever fails, you simply replace the MCOR4 (105116301). It's much cheaper than the old MCOR was.

Re: MCOR / Pedal Assembly Confusion Explained
 

Have a question or two. My cart 2001 electric 48volt has no power going up hill.
Also going down hill free wheels, no lag from the motor. First electric I've owned know it should be able to climb because I play a lot of golf and they climb very well.

Any help out there

Re: MCOR / Pedal Assembly Confusion Explained
 

Post a new thread about it in the Electric Club Car section. This thread is about another topic. There will be lots of people willing to offer free advice.

Re: MCOR / Pedal Assembly Confusion Explained
 

If I may say so Tahoe is a very honorable businessman and has the parts along with support believe me I learned the hard way thx tdog

Re: MCOR / Pedal Assembly Confusion Explained
 

Thanks for the info. it will come in handy. I hope this takes care of my issue

Re: MCOR / Pedal Assembly Confusion Explained
 

So maybe you can tell me what I need , 2009 PH precedent with jerky speed, does clear after numerous throttle cycles, does have a plum quik motor which seemed to exegerate the jerkiness .Attachment 136103

Re: MCOR / Pedal Assembly Confusion Explained
 

AM293001 MCOR4 conversion kit. By the way, that's me that you're chatting with via ebay messages.
