Multi-Step Potentiometer versus MCOR1

brunson67

Hello,

Hoping to get some help on this. I'm helping a friend rebuild a Club Car DS 48 volt, I believe 1997. It has a multi-step potentiometer, and black plastic half moon shaped item in between the batteries. I have an extra FSIP 500 AMP controller that came off my 2001 48 volt club car, which I believe is a MCOR1. It has a small black plastic box on the right side of the frame rail attached to the pedal assembly.
1. Can we use this 500 amp controller on this older multi-step potentiometer?
2. What's the difference between the 5-0 and 0-5 ohms requirement?
3. If this will work, will the stock 2.75HP motor be okay with the 500 amp controller? Only until he can upgrade to a new motor.

I have not only the controller, but heavy duty solenoid, and #4 cables as well, so if this will work we can do this on a budget. Thanks!

BGW

Good news - The 97 and 01 carts both use the same 5k-0 throttle signal so the control will work with the multistep in the 97 .
You can use the 500 amp control with the stock motor. The driver will decide if the motor lasts a long time or a short time. Slow operation, big tires, heavy loads, deep footing & hard starts all make the motor consume additional amperage. Not all the amperage going to the motor is converted into power, some is converted into heat. So keep an eye on the motor, you should be able to hold your hand on it at any time.

Hello Scottyb - Thanks for the response. This will really help my buddy out, as Im giving him a really good deal on the controller, solenoid, cables, etc, plus my labor! LOL
What about the motor, will it be okay with the 500 amp controller until he can afford a new motor?

Thanks,
Rob

The answer is yes, hidden in my first response.

brunson67

Sorry, somehow missed that, thanks!

No problem, Sounds like a good project. Have fun!

One more quick question - I haven't ever used the conductive grease between the controller and mounting, is this critical?

It does help the heat to transfer from the controller to the sink and that's a good thing. It can potentially extend the life of the controller.

Had a feeling this would be the response, and of course my cart is completely put together!LOL

Thanks

It's still going to transfer heat without it but tin foil hat guys will go so far as to mill both surfaces to insure 100% contact and apply the heat compound. You know 95% of all controls go in with nothing...
