Default Controller or ITS?

I need some help to determine if my cart problem is the controller, motor, or ITS.

Cart simply died making a right hand turn. It made a few lurches after that but not very often. Battery pack is almost fully charged at 37V+. Everything else still works. Solenoid activates, radio, lights, all wires are tight. I tried to follow ScottyB's EZ-Go Diagnostics but am totally lost.

1996 EZGO TXT Non-DCS Non-PDS



1. I've got about 500KΩ between the two disconnected terminals of my ITS.
2. I've got 0v@ no depression
.51 @solenoid click
1.6 @full throttle
3. ?

Its is voltage. 0.5 to 1.5 or close to that...
Have you checked all the cable connections at the F&R and Motor?

Have you tried a jumper across the large terminals of the solenoid? If the cart moves it's not the controller but either a bad solenoid or control wiring.
Do you have a reverse beep?

I've not had a reverse beep since I put in the HD F/R. But no... I haven't jumpped the solenoid yet.

Sounding like a controller issue, is your controller stock or an aftermarket upgraded amperage model?

I thought it MAY be the controller but... below states that...

And my voltages are off compared to this service manual. So I want to be SURE before I buy a $350 controller and/or a $150 ITS
