Re: 1990 EZGO Solenoid Dead?
Sounds like a bad controller. Only other thing it could be is throttle. I’m assuming this cart has ITS throttle. It’s located under mat on floor. There is a sticky in this forum that tells you how to check it.

Here is the ITS stuff for a Series drive.

Re: 1990 EZGO Solenoid Dead?
Doesn't look like I have ITS. Appears to be a simpler potentiometer system?
I ran the B- to Controller Pin 2, and it reads about 4V when the pedal is pressed far enough to engage the solenoid. B- to Pin 1 reads 4V before pressing the pedal and stays about the same as the pedal is pressed. It then goes down to 1.5V at full pedal. Before the cart stopped working I had been doing some adjustment to the throttle linkage, as it was reading about 7600 Ohms with the pedal fully depressed. After my adjustment I got it down to about 5400 Ohms, and it ran fine for a couple days before it quit altogether. |

Re: 1990 EZGO Solenoid Dead?
It's definitely seeming more and more like a bad controller. What should the behavior of M- be? From the circuit diagram it looks like that's the terminal that needs to complete the circuit for current to flow, correct?
While messing around we ended up bridging B- and M- with the pedal pressed, and the cart moved, so at least it appears the motor is functioning. |

2. Yes. The speed control element (MOSFETs) is located between B- and M-. 3. That bypassed the controller. |

If the controller is turned on and being told to pass amps to the motor, but isn't doing so, it is bad. |

Re: 1990 EZGO Solenoid Dead?
Double checked and yes, very close to 0Ω with pedal up. 5400Ω when pressed to the floor.
