Default Surging at slow speed

I have a 2007 club car precedent, it has 2 month old trojan batteries. 4 of the 12volt. It has a new OBC. A new voltage reducer for all my lights and accessories. When they put the new obc on they put in speed code 4. It also has the speed magnet in the motor. It just started surging st liw speed. Ejile im going sliw through our trails , it is heditating then going, but on the road at full throttle it does fine. Is my MOCR going bad.

If you have a speed magnet, the sc4 is not needed. Yes it could be the mocr. Try pushing the pedal to the floor 20 to 50 times with key off. If that helps it is the mcor.

Ok. Could the speed code be the problem. Thanks ill try that, will the speed code 4 cause the batteries to go down quicker ?

Sounds like an MCOR problem to me.

Sc4 has really nothing to do with batteries going down.

Definitely the mcor... I've noticed on club cars that when a fresh set of Batts are installed a month or so later the mcor goes. Don't know if it's the fresh strong Batts but I've noticed a pattern

In a round about way yes..... Are you driving the cart faster?

And the surging at slow speeds sounds just like an aging MCOR so you need to talk to David Hicks and update it too....

MCOR and OBC are the 2 most common complaint with these carts.

Agree by far.... The MCOR-2 in my cart was crap at purchase last year, found out the hard way MCOR-3 is crap too, the MCOR-4 did the trick.... The OBC is now out of the charging loop and I will finish the bypass and remove the bugger soon enough....
