I picked up a multimeter the other day and am still learning to use it, how do I check for a short with my multimeter?
and lastly, I'm not using a relay, should I get one?
thanks again TW!
Yes use a relay. If it was shorted, you should have a blown fuse. Or the switch was underrated for the lights. This would make it act like a fuse.
A short means a direct path to ground (in this case). You would have your meter set to Ω. You need to find the side of the switch where the power would go to the lights when the switch is thrown. One lead will be on that and one goes to ground. If you get a small reading then there is a short.
