After launching the boat, and not disconnecting the trailer plug, the running lights will not go off at all, with out pulling the fuse. The alarm that indicates the key is removed (with lights still on) also blares untill the fuse is pulled. After the dealer couldn't identify the problem, it worked normally for a day. Is there a relay in this loop, or it it simply a short, or?

 

warrenty?

I never unplugged my lights before, but now with $100+ in LEDs.... why should I? they are 100% water proof, vibration proof, etc!

the only thing i guess is electric brakes if you have those on the trailer...

trailers should have a float switch that kills the trailer link once you dunk the trailer...

i hate always having to unplug / replug that crap!

 

I always unplug my trailer before dipping the trailer, just a good habit to get into.

 

you might have water in or behind the plug on the truck ,night have to blow it out with compressed air inside and were the plug hook's to the harness .water could be shorting across terminals .
