half way down on the pedal the motor dies
i don't know what year it is. it's an older 4 wheel model with rear seat. i just put in new batteries for this 36V system. In reverse it does fine but in forward it dies about half way in on the pedal. i have to release the pedal all the way before it will go again. From the pedal it has mech. linkage back to a small box with a micro switch on top (potentiometer?). Any help will be greatly appreciated!

Re: half way down on the pedal the motor dies
yes it did. i had the cart out at the hanger un attended for a few month and the old batteries got to low to charge anymore. i have the cart home now and want to get it working right and after my model A build i'm going to do something with the cart.

Re: half way down on the pedal the motor dies
What model do you have? What electronics? Pot box? Wiper Arm style? Controller?

Re: half way down on the pedal the motor dies
Do you have an ohm meter? If so in your 3rd picture just underneath the red battery cable you will see your controller. The white and black wire that are bundled together come from your potentiometer. Disconnect these from the controller and hook up your leads from your ohm meter to these wires. With the cart turned off, you should see 0 ohms. Slowly depress the accelerator and see if you have a nice steady increase as the numbers on the meter go up. With the accelerator fully depressed you should not see any reading above 5500.

Re: half way down on the pedal the motor dies
ok, my meter is digital so seeing a swing on the pot is difficult. i did this a few times to check for accuracy and i got a swing from 0 to 7.33K and right after 4K it dropped to 0 and then back up and continued the swing up to 7.33k. it was a quick drop too. was like 4.0, 0, 4.2, 4.6, ect.
