How to wire 36 V solenoid on Yamaha Golf cart Need to which wire goes to motor & to the battery

It depends on the model, but they are usually wires in series to give 48 volts to the motors, so plus to minus on each them.

Cart positive lead to batt 1 + the - to batt 2 + to batt 3 - to Batt 4 + and the minus - of batt 4 to the cart.

It's possible that the motor, solenoid, or wiring has become disconnected or damaged. I recommend starting with a basic inspection of all the connections, wires, and components. If all looks alright, then you may need to have the motor and solenoid tested. If there is still no luck, then you may need to replace the EZGO golf cart motor or solenoid.

If you are getting full voltage to the motor and that is the best you can do, then you have no recourse other than to change the motor.

The solenoid should click when cart is switched on.When it clicks on it sends the full voltage to the motor controller and motor.Check the voltage going to the solenoid with a volt meter on the thin wires.

Verify series battery wiring. The main positive wire which goes to the solenoid should be on a positive battery post, that will be your main positive. Then from there we go series to all the rest of the batteries until we are left with a negative battery post, that will be your main negative. Make sure your charger wires are connected to the mains.

First of all, lift rear axle off the ground and place blocks or jack stands underneath. Check to see if you have 36 volts On your batteries. Now you want to run a jumper across the big cables on the solenoid. Press the accelerator and the motor should engage. Clicking is a pretty sure sign that the solenoid is bad. Please let me know if this is useful. I can further elaborate more troubleshooting if this doesn't solve your problem.

Do you have a multimeter to check DC voltage ? You possibly could have the batteries hooked up wrong and not getting 36 VDC. Also did you replace with the same number (6) 6 volt batteries or three 12 volt ?

Its been a wile but if I remember right it goes from the solenoid under the cart (pass side) to the key switch (the other wire is probably volt meter) then micro switch,green wires from micro switch to controllern. Inspect all spade connections
