Intermittent Headlight Failure and More!

[team_ream]

Hi Everyone,
I'm having an issue in which my headlights (daytime and regular) occasionally do not come on at all. I can't figure out how to replicate it or how to get them to come back on. Usually I'll just turn the car off and on and most of the time it works. It was so intermittent at first that it wasn't a big problem but now it is happening with increasing frequency and I'm guessing at some point they will stop coming on altogether.

Also, there are some other electrical gremlins that occasionally show up too. My clock resets, stereo turns on and off (sometimes not for days and other times it will happen every 30 seconds). These electrical failures also seem to be coupled with non-working dome-light.

Any suggestions where to start tracking this thing down?
Thanks!

The headlight issue is usally a poor ground connection where the light is held into the headlight housing . Your other problem sounds like the plug that connects the fuses to the battery post is going bad you may have to pull out the battery/batteries to get at it .Cheers Jay

I agree with overlander. I don't have any specific Delica experience but it sounds like a poor power or ground cables. The power and ground cables tend to get bad over the years . Moisture enters the cable insulation and corrodes the inside of the cable. Instead of a nice copper colour your wire can look green or black when you open it. This causes a voltage drop. The high resistance causes the wire to get hot under large loads. (I.e. the headlights are on). I burned my hand on a battery cable before. The warmer the wire gets the higher the resistance.
Like I said, might not be your problem but good to keep in mind.
Good luck.
