i have a 1987 EZGO 2 stroke 3 wheel metal body golf cart. Issues with starting I tested ignition switch its good, I tested micro switch on pedal its good, I tested solenoid its good, battery has 12.75 volts its good. Here's the problem I turn on key hit pedal and the starter tries to turn over but it just can do it just pulsates. I hit a hot wire on starter it turns over fine. Any ideas or what am I'm missing?
