Lights not working on Star golf cart. Fuse is good. How do I check switch?
Buy or borrow a voltmeter, check the voltage across the batteries, the light bulbs, and the switch open and closed. The full battery nameplate voltage should appear across the battery, and across the light bulbs when the switch is closed, and across the switch when the switch is open. If these are not true, you need to look for breaks in the circuit. To do that, turn the switch on, check the volts across the battery, keep the negative connected to the battery, but disconnect the positive voltmeter wire from the battery, check the voltage on both sides of the switch, if they each match the battery voltage, move on to checking the voltage on each side of the light bulb. If one side of the bulb matches the battery voltage and the other side is zero the bulb should light. If not Change the light bulb. If both sides of the bulb match the battery voltage, then there's a break in the wires between the bulb and the negative side of the battery.
Now going back to the switch situation: with the voltmeter negative still connected to the negative of the battery, if one side of the switch matches the battery and the other side of the switch is zero, either the switch is off or broken. Turn the switch on and off a number of times measuring the two voltages each time. If you can't get both sides of the switch to match the battery, the switch is broken, replace it. Good Luck GooseBay_Camper.
