1/2 speed reverse

Foytfan · 10-13-2013, 08:00 PM

Is there a way to disconnect it all together? Problem is I run 7 to 8 mph in forward or reverse. I'm hoping that some how the switch is marketing this happen. That's way to slow for any cart. 93 marathon controller 36v good batteries and good wires.

yes you can.....but if you are going half speed in both f & r.....you have another problem.

but tell us a little about your cart....what year? model? which drive system does it have?

hopefully JohnnieB will be in, as I won't be much help with a Marathon as for any specifics on your issue.

I'm not Johnnie but ... The stock Marathon potentiometer had 2 leads. The shorter lead sends the out put signal and connects to the controller. The longer lead connects to the reverse ms on the F&R. When these 2 wires are connected to each other, (switch on) the pot output is reduced by 50%. Hence 1/2 speed reverse. Simply disconnect one or more of these 2 wires from the F&R ms to disable 1/2 speed reverse.

no you are not.....lol I didn't know you were on at the time, but thought Johnnie was. I knew that one of the two of you could help.

Could this some how cause 1/2 speed forward and reverse?

Yes. If you have a pot box, the 1/2 speed microswitch adds series resistance, making the throttle think it's only 1/2 way pressed.

Actually, a fixed resistor in series with a variable resistor (potentiometer or pot) is not linear, but gets the job done.

EDIT: just answering the question "could..." It shouldn't if it's operating correctly, but it "could".
