head light low beam issue
My low beam has been working inconsistently. I thought it was the dip switch. I changed it but the still no low beam. I changed the fuse (which I should have done in the first place) and low beams worked, 2 days later, no beams, low or high…. I changed the number 1 & 2 fuses, high beams came back, still no low beams or main fog lamp bulbs. I used sandpaper on the fuse clips, nada… I’m not sure what to look at next… Ideas?

Smonop,
Let me start by saying the obvious; electrical gremlins are difficult to track down, and I hate electrical gremlins. Arm your self with patience and a voltmeter.
1.The fuses you replaced, were they really burnt or did you replace them to make sure it was not a fuse? Unless a fuse is visibly burnt, I always check them with a voltmeter.
2. I would not use sand paper to clean any electrical contact (sand paper contains and leaves behind silica which is not conductive). Use a red scotch abrasive pad, emery cloth, or maybe even steel wool (careful with the little pieces of steel that can fall of) to clean contacts.
3. check the ground wires. Intermittent lights can be the result of a loose intermittent ground.
4. Yes, it could be a relay, or the light switch, or a loose wire making an intermittent short. Check one thing at the time and clean contact points as you go.
Wish I had something more specific for you to check, but this is the nature of electrical problems.
Good luck.
Bill.

Smonop,
If you are getting a new voltmeter, make sure you get one with an audible "Beeeep" for the continuity check. Some times you can be in a position where you cannot easily see the digital display. If you hear the beep you know you have continuity even without looking.
Good luck.
