I received my headlight relay today and decided to install it even though I might not have needed it. It provides power directly from the battery to make sure the ballasts have adequate power at all times. I thought I might as well put the capacitors in too. I got it all installed, double checked my wiring and turned on the lights.
The driver's side headlight didn't work....then I saw smoke...then a small pop.
The capacitor on the driver's side must have had the polarity reversed, this shouldn't have happened as the plugs can only be inserted one way. I checked the wiring on the plugs comparing the polarity to the other capacitor and the were the same. I then proceeded to cut the plastic housing from the capacitor to check if the red wire went to positive on the capacitor but it was thoroughly encased in resin.
I left the relay connected, it works fine, not sure if it's any better till I drive it to work tonight. I suspect it will simply be the same as without the relay.
I've washed my hands a few time now and they still smell like a fried
dna board.
