Re: Fuses Blowing
I too have a 5 amp fuse for my anchor/running lights and 5 amps for me is more than adequate. First I would pull the bulbs out, turn the switch on and see if you still blow fuses under "no-load" conditions. If you do, you probably have a short in the wiring or in the switch itself. If not, put the bulbs back in one at a time until the fuse blows. At least you will know the culprit bulb. It is possible that the bulb is about to go and is pulling more current than normal. Then I would replace that bulb and see if that fixes it.<br /><br />If you still blow fuses with the bulbs out, you will need to get your hands on an ohmmeter or some continuity tester that will let you trace the circuit looking for a short circuit. Disconnect the wires from the switch and use the continuity tester to see if the wires are shorted somewhere along their length. Put one tester probe on one wire and the other probe on the second wire. If you have any continuity, your wires are shorted and you will have to rewire the light.<br /><br />If your switch housing is connected to -12V through a metal dashboard or something like that, the short could be happening in the switch itself and if so, it needs to be replaced. You can check the switch by putting one tester probe on the switch housing and the other on each terminal. Turn the switch on and off and see if you have a circuit between any terinal and the housing. If the switch housing is electrically isolated from -12V then it probably isn't the switch. <br /><br />Good luck!!
