Default 1995 Ez Go won't move

I'm sure this has been posted before but I cold not find anything through the search. When I press the pedal nothing...only a click. I replaced the solenoid and still nothing. I have 38.7 volts across the two large posts. All battery conns and conns on fwd/rev switch look good.

Welcome to BGW!

To help you troubleshoot cart, we'll have to know what types drive system it has.
If it has a Run/Tow switch on controller's environmental cover, it's a DCS type drive.
If it doesn't, it's a Series type drive.

Since you have over 38V at the solenoid contacts, the battery pack is probably good. Or at least good enough to troubleshoot with.
Since the solenoid is clicking, the problem is most likely in the high current circuit.

With either type drive system, connect the negative DVM test lead to the battery pack's main negative terminal.
Connect the DVM positive lead to the A1 terminal on motor. (or the M- Terminal on controller, the other end of same cable)
When the solenoid first clicks, you should read full battery pack voltage.
If not, you've got a bad cable, contact or connection in the high current circuit.

Need to know drive type to suggest further troubleshooting steps.

It does not have a run/tow switch on it. The cart ran fine when I bought it, got it home changed the headlights, added a rear seat and when I went to move it...nothing. I charged the batteries thinking maybe the previous owner had not done that...still nothing. I will check what you suggested at lunch and post my findings. Thank you!!!

Where did you connect the headlights?

Okay. It is a Series cart. (Meaning it has a Series wound motor.)
If it has a metal body it is a Medalist and if it has a plastic body it is a TXT.
Here is a schematic for a series cart with the high current loop traced.

You say you changed headlights. What exactly did you do?
If you messed with the wiring any, something might have been knocked loose or put something back in wrong spot, or not reconnected at all. (Stuff happens. )

The head lights are connected across two batteries. They were on the cart and functional when I purchased, I just upgraded to a smaller halogen style. I don't think I changed any wiring b/c I went to the same two batteries and the lights are working.

Is it possible the click you are hearing is the microswitch at the throttle ? Just to be sure put a volt meter on the two small lugs of the solenoid and then press the gas. You should see 36+ volts.

1. It should read 38V with F/R in F or R, Key switch on and Pedal pressed until the solenoid first clicks, but it sounds like the solenoid is activating before pedal is pushed.

2. You shouldn't read battery pack voltage across the solenoid's small terminals until the pedal is pushed.
MS-3 in pedal box is either out of adjustment, broken or the contacts are welded together, or the wiring is mixed up someplace.

Here is a schematic with solenoid activation circuit traced.
Make sure it is wired correctly.

Also, there may be more than one problem.
The cart will still move if the solenoid stays activated all the time the Keyswitch is On.
