Re: MCOR / Pedal Assembly Confusion Explained
 
I took inventory of my MCORís and the serial numbers donít match anything youíve documented in the first post TahoeDawg:

PGM10066810
PGM10066811
PGM10066814
PMA10019355
PMA10052900
PMA10059506
PMA10052907
PMA10052909
PMA10052914
PMA10059516
PMA10052918(bad)
PMA10052921
PMA10052925
PMA10052926

Whatís the proper replacement for these wretched parts? Theyíre mounted on 2012-2013 CC Precedent Excelís, so these serial numbers donít make sense.

The serial numbers I mentioned are vehicle serial numbers. The serial numbers you mentioned appear to be serial numbers off of the pedal assemblies. These numbers don't tell me anything.

it’s funny how the barcoded serial number on the pedal assembly can’t help me... it looks so big & important TahoeDawg!

Okay, so only the VIN is relevant. I’m assuming that I’ll need a conversion kit to install a MCOR4.

So I took the extra step to remove the pedal assemblies and found the part number that you referenced on post one. Obviously no adapter is necessary, thanks.

They might not all be that way. That cart has an mcor 4 dated 2014. It may have already been converted. I canít recall what year your cars were. You may have a mixture.

Re: MCOR / Pedal Assembly Confusion Explained
 
Had my throttle pedal stick on me yesterday and went in search of an answer for a possible replacement spring assembly of some type and subsequently learned so much more along the way. What I discovered is that I probably have a failing MCOR as well because I do get some surging. Cart is a 2008.5 Precedent electric with a Group 1 pedal assembly. It looks like I can buy a new spring assy for the accelerator for around $60 if I need it. The pedal returned to the upright position on it's own eventually so I'm hoping it just might need a good cleaning instead. So here's my question...if I open this thing up this weekend and find the spring is terminal, would I be better off shopping for a refurb Group 2 assembly and moving to the MCOR 4 or repairing my Group 1 and replacing the MCOR 2 at the same time?

So I am guessing that when going slower and I am getting some slight jerking (speed up and slow down) that the MCOR is probably the culprit. Just want to make sure before I order one. Dave, i'll order from you. It's a 2014 ERIC cart is am pretty sure it's a MCOR 4.

You are correct. Itís probably an mcor issue. And yes, itís an mcor4.

Did you order it from us? If not, pay close attention to the sticker on the side of the MCOR4. If it says "CHINA" on the label, it's junk. Replace it with an OEM version.

I recently bought an MCOR4 from a competitor that is also a site sponsor. The faulty one said made in Mexico. The new one said made in China.

It has corrected my lunging by about 80% but it still happens.

Was the Mexico MCOR4 new? If so, you need to contact whoever you bought it from and get them to swap it out for you. Nothing is perfect and sometimes good stuff fails, but the failure rate of the aftermarket Chinese MCOR is far higher than the OEM components. If your lunging is still happening, it's probably because the Chinese MCOR is not working correctly. Replace it with a new factory unit and see if it does the trick. It should correct your lunging by 100%. When those Chinese MCORs came out I bought a whole box of them. Spent the next two weeks going to customers houses and swapping them back out to factory units because 80% of them failed.
