Power issues
Here's the issues, 2001 club car ds, speed motor, 4 gage cables, heavy duty f/r. Had issues moving at all and the controller smelled burnt. Replaced that with a new 500 amp controller and the solenoid was not working and when tested was not doing anything so that was replaced. Still nothing. No clicking of the solenoid or anything. Thought mcor was next. It had been previously upgraded to an Mcor 3. Installed a new one. Now we have movement however... It has full power under about half pedal. And it cuts off after pedal is pressed over half. There is no slow roll to it. it's balls to the wall or nothing. Mcor only goes in one way but it seems to me like it's 180 off or something. By the way the controller and everything that was replaced was all newer in the last few years to begin with like the controller it was a 500 amp before. Stock was gone years ago.

Re: Power issues
What brand is the controller? If it's an Alltrax you can hook a laptop up to it and tweak the throttle settings. Or if it's a GE you should be able to use a screwdriver to adjust manually. It sounds like they're a little out of whack...

Re: Power issues
Think its a GE has three little caps on the side I assume are for screw adjust? I just put in the factory mcor and it down the same thing. I then rest the obc and it goes better. Its jerky in reverse and slow with pedal to the floor and fast at half pedal where before it shut off at full pedal. I'm kinda scared to mess with the adjustments in the controller.

Re: Power issues
I'm guessing the three blue plugs on the top side are some kind of adjustment. This is the same controller I took out that was in there about 3 years he told me today.

Re: Power issues
Those are good controllers. I love them. I use them on all my series conversions.

Re: Power issues
I'll give that a try tomorrow and let you know what happens. Any ideas also for a good controller for a 2001 regen? I have 6" of lift and 23's with the stock controller and it rolls at about 16mph. I'd like 25ish.

Re: Power issues
The issue is that You have the wrong controller for an MCOR.
You have a "51-42L500NN0S" which is a 0-5kΩ throttle, but You should have a "51-42L500NNVS" which is a 3 wire 0-5v setup. The resistance of the potentiometer is not too important on a 0-5v setup as it is on a pure resistance or rheostat mode. If You cannot exchange the controller for the right type, You can make some modifications to the throttle signal to get it to work better. I also assume You must have removed (or will need to) the micro switch #3 for half-speed reverse as it would not be compatible with your controller. This should be the original wiring diagram for your cart: http://www.buggiesgonewild.com/attac..._with_mcor.jpg Can You verify which MCOR wires you have plugged to Controller #2 and #3 Terminals? |

Re: Power issues
Update:
Sergio was correct. I pulled the mcor back out and installed in back on my cart and put the mcor 3 back on this cart. I noticed that the controller number was off on the last few digits. So on a hunch I put the old controller back in and don't you know it worked! Must have been the solenoid that was burnt and I thought it was the controller I smelled so she's all good. Must have killed the mcor when the solenoid went out and we thought it couldn't be the mcor because it was like a year old. Thanks for all the help guys!!! |
