Hello, I am new but I am hoping someone can help. Driving home tonight got a bit scary while driving through a construction zone. Every time we hit a decent size bump the headlights and all interior lights flashed off. Fortunately they just blinked off and came back but it happened four times. I was wetting my shorts waiting for things to go lights out permanently. Has anyone experienced this before? Any clue where to start looking?

Make sure the battery cables are tight, and re-squeeze the crimps with a large pair of pliers.

At the back of the trunk are two master fuses...make sure these connections have not loosened.

There is also a heavy wire master power connection at each fusebox. Make sure these have not loosened either.

For safety, disconnect the battery before touching a tool to any 12v connections to prevent accidental shorts that could burn you.

 

Thank You, I will start there in the morning. I love your website by the way and will be purchasing your kit to make my temp and oil pressure gauges real. I hate things that appear to be something they are not, so I will be rectifying the gauges in my car soon.
Appreciate your time, Mark
