Underwater Light Circuit Fault

[blueroom]

Hi

I am getting a Circuit Fault / Overcurrent error when turning my underwater lights on. It had happened previously when the engine was running, but now it happens with just the battery switch on and engine off when switching the lights on. Lights blink on briefly, LINC shows CIRCUIT FAULT and an overcurrent error shows in the the power diagnostic screen. Boat is a '16 G23.

Thoughts?

I may be wrong, but was under impression that most of the underwater lights were "water cooled" and not supposed to be run out of the water. Could that be the issue?

Don't think this is the issue, as they don't really turn on - the fault happens immediately. It also happened on the water that last time I tried them, but the engine was running and I thought it might be a alternator/voltage regulator issue. Given it is happening with the engine off, that is not likely.

My GS 22 had that happen. They replaced both lights.

My GS 22 had that happen. They replaced both lights.

I had one of my underwater lights replaced as well under warranty

Scoma and GMLIII - Good info. Did the bad lights cause circuit faults? Or did they just not work?

[GMLIII]

No it just didn’t work . Loose connection and the light cut on and off so dealer replaced

As suspected, the underwater light circuit fault - overcurrent - was due to a bad underwater light. Replaced and good to go.
