Do you have a voltmeter to test with? Does your charger show to be charging the batteries? Is this a 36 volt cart? Does it have battery voltage at the charger connection on the cart? What kind of control does it have? Old resistor type with a set of resistors in a metal box with multiple cables to motor? No number /letter tag at the passenger side glove box?

hi its a sit on 4 wheels single seater throttle control 4 new 12 volt batteries basic buggy .it has a small motor throttle control 4 battery power source 2 connections to motor some kind of relay about 45mm cube and some kind of joint box or small inverter .the throttle has power indicator this was working but befor I fitted the batteries the red light came on

Expert:  Curtis B. replied 3 years ago.
Does the charger work when plugged in? This verifies that the batteries have complete primary circuit. The foot pedal control works the controller , to vary the voltage to the motor to vary speed. With red light on, it seems that the controller has incorrect voltage.

hi Curtis b the charger works the throttle is twist grip the relay thing is jqx 38f 40 amp 3poles dt

Expert:  Curtis B. replied 3 years ago.
the twist grip has to be a rheostat. Check it with an ohmmeter and see if you get a even , gradual increase as the throttle is advanced.
