Light GFCI

Moderator comment - Moved from here: Pool Light is Tripping the GFCI

Not to hijack but I am going through the exact same thing. I checked continuity on the lines out to the junction box thinking something may have shorted and did not show a short. So I am stymied as well.

Thanks

Electrical shorts that a continuity test detects would show faults that trip a standard circuit breaker, not a GFCI.

The type of leakage faults that trip a GFCI breaker are quite different and require a megohm meter ("megger") to detect.

The OP has pretty clearly narrowed it down to an actual fault on the load side of the GFCI. If the FiberStar Illuminator is the only load, that, or the wires that feed it are the likely culprits.

Got mine working again and feel pretty stupid....when I changed the GFI I mixed up the neutral on the line/load side reversed them back and problem solved.

How did the wires get mixed up in the first place if the GFCI was tripped before you replaced it?

When I replaced the GFI I was not paying attention to the line/load side of the neutral and had them reversed.

Never mind, I got confused thinking the problem you solved was the one the OP had. Got mixed up that there was two different issues going on in the same thread
