LED masthead light problem

So, I hooked up a hella NaviLEDtrio, had the tricolor working for a few minutes, but then think I crossed some wires and now I have nothing. My friend showed me how to use a meter and it shows no continuity on all combinations of the three wires. Any suggestions? Yes, I blew the fuses attached to the Anchor and Nav lights.

Re: LED masthead light problem

It's unlikely that you'd blow a LED nav light by simply crossing wires. So it's more likely a wiring problem. Remember that LEDs aren't like incandescent light-bulbs; the polarity (+ / -) must be correct.

Not all multimeters will show continuity on LED lights. Simplest test is to try the lights one at a time with 12v through something like a 5A breaker (unless you have lotsa of fuses ), at dusk, so you can easily see the lights. If the breaker pops you have a short in the wiring.
