Resistor?

[RobRoy]

Electric 36 volt EZ Go. Tested across the battery pak = 37.9 volts (New Batteries). Tested to battery side of solenoid = 37.9 volts. Tested to controller side of solenoid = 4.2 volts. All connections OK. Is this a resistor problem? Where is it located? Solenoid problem maybe? Thanks for the help. I am a newbie to this forum and to the world of electric buggies.

Oops. Error in first post. Apparently with the brake locked on the solenoid is not energized. I bumped the accelerator pedal to knock off the brake and now I get 36.9 V on the Controller side of the solenoid as the initial reading.

The problem I am having is that the cart runs fine on flat ground but has a very difficult time going up an incline. It is extremely slow and requires that I traverse the incline to get up. Also it smells "hot" after a climb. Perhaps because there is a lift kit and "knobby" tires on the cart my controller can't produce enough power for low end torque?

Do I need a stronger controller module? The one I have in the cart is a Curtis PMC P/N 25864G05 and S/N 2168-P129002.

Again, thanks for the help.

The controller, solenoid, cables, and F&R (series carts) need to be upgraded when larger tires are run. Some guys even upgrade the cart's voltage.

DO I need to post the tire size to know which upgrades I need? Upgrading the wiring is no problem but how do I know which solenoid/controller to get? Where is the best place to get the parts? Thanks.

From my website, I try to help people add up all the determining factors which make up the selection equation .... Not only tire size but other options like terrain and load need to be factored in...
