Re: New brake lights turn signals not working. What could be the problem?
I just installed a brand new light kit on my boat trailer and I did everything correct. The brake lights work and so do the hazard lights but when I turn on the right or left turn signals both the lights flash like the hazard lights. Could this be a ground problem I think I have a good ground connection but could be wrong. Has anyone else experenced this and what have you done about it.
Logic says that if you have any working lights you have a ground. The same ground works for all lights.
How did you make your connections? Crimp, soldier/heat shrink, little blue clips?
I would begin at the beginning, assume nothing. One of my trailering buddies had working hazards but the left signal was bad on his new LEDs, after they had been working for 2 months.
Using a multi meter verify proper current from from tow vehicle.
Disconnect all splices.
Re-attach each wire, verify proper operation before moving on to the next wire. Start with one of the signal lights 1st. Then move on to the next.
It is possible, if using incandescent lights, that a bulb is at fault, or a socket is funky.
Go step by step, and you will find it. Or at least you will fix it, even if you don't locate the exact problem.
I prefer soldier, but most use crimp ons. Use quality connectors only, not the "little blue thingies". Heat shrink each connection using quality "adhesive filled" heat shrink. Care now pays dividends latter.
