ezygo won't go

[humptydump]

ezygo 92. Solenoid clicks when u push pedal but will not energize motor. 36V. Full charge on batteries. This has been occurring intermittently recently until finally will not engage drive at all. I am not experienced in troubleshooting golf carts. Thanks in advance for help.

Sounds like a bad solenoid or F&r to me. Solenoid clicks doesn't mean solenoid works. Check f&r for sunken or otherwise damaged contacts. 36v does not = full charge...

Since the problem became more frequent don't count out a bad throttle signal device. What controller do you have ? Do you you have a multi-meter with a fresh battery in it?

36 V was used only to designate cart. Checked solenoid with meter and checked OK by posted method.... "On a typical solenoid there are four posts called terminals. There are usually two large terminals and two small ones. Battery voltage is applied to the two small terminals to activate the solenoid, which then connects the two large terminals together. From time to time the two large terminals malfunction and the solenoid needs to be replaced. To check the solenoid is fairly simple, though. Follow these steps":

1. You will need a couple of tools: a voltmeter or multimeter, and (typically) a ½” wrench.

2. Disconnect any cables from the two large terminals. Be sure to wrap the cable ends in tape, and keep the ends separate from each other.

3. With the key off, and the cart direction switch in a neutral position, set your voltmeter to ohms, and place a probe on each large terminal (see first image below). There should be no reading.

4. Now, with the cart's direction switch in the forward position, and the key on, step on the accelerator. You should hear a click coming from the solenoid. If you do...

5. Set your voltmeter to measure ohms, and place a probe on each large terminal (see image below). You should have a reading of 0 to 0.4 ohms. Anything higher, and it means that the solenoid has faulty contacts and should be replaced.

Is there a better check? Thanks

FYI if the solenoid has a pre-charge resistor on the 2 big terminals you will always read voltage across the big posts... disconnect one end of the resistor for testing

F&R...when in R buzzer sounds....solenoid clicks when accelerator is pushed down appx. 20%

Disconnected all wires from big posts

What (and where) is throttle signal device?

How to check F&R switch? Thanks

Scottyb I get no voltage across large post on solenoid with F/R in forward and switch on?
