We need to identify what kind of EZGO cart you have to get into detailed troubleshooting, but there are a couple things that apply to all types.
What is the battery pack voltage? (For a 36V system, 38.22V is fully charged.)
What are the individual battery voltages? (6.37 is a fully charge for a 6V battery)
There should be a letter and number stamped into the Negative terminal of the Trojan batteries. Letter is the month and number is the last digit of the year.
If the solenoid is clicking when it should, the problem is in the high current circuit or throttle circuit, but need to which type drive to go further.
Here's a drawing to help you ID what type drive you have. If it is pre-2000, it either be a DCS or Series type.
Also, plug your cart's serial number in here and it will tell you what it is.
