I would recommend 2 things. Excuse me if you've tried this, but looks like you
were probably looking for light from the bulbs as your indicator.
Connect the ground/negative lead from a multimeter to a known working ground.
Use a long piece of 16 or so gauge wire to as an extension if needed.
Disconnect both headlamps.
1 - Check the voltage at the high and low beam connections with low beam
selected. Do both connectors. Write it down.
2 - Check the voltage at the high and low beam connections with high beam
selected. Do both connectors. Write that down, too.
No, not 2 things, 3, yes 3..... (Obligatory Monty Python reference)
Now, turn off everything electrical that is possible. You should always do
this before checking grounds, as currents through the ground circuit(s) can,
and probably will, throw off the measurement, and may, but probably won't,
damage your test equipment.
3 - check the impedance from the ground connection to the ground connection.
This is to give you a reference on how much impedance your leads, esp if you
added an extension to get to a good ground, are adding. Again, write it down.
Check the impedance from your ground side on each of your headamp connectors.
Write those down. (I really believe in keeping records, makes my poor memory
less of a problem) Subtract the "ground to ground" impedance from the
"connector to ground" impedance. This will give you a more accurate value of
that connector+wiring harness ground impedance value.
Hopefully the answers will help. If not, you know what the problem isn't.
Anyone may feel free to ask me about any electrical/electronic problems, etc.
anytime, on or off the list, whether vanagon or not. I'm an EE and a ham, and
I currently work as a sysadmin and security guy at an ISP, so networking and
unix questions are OK, too. No, not the one where this email originated. And
if you have any win problems, please seek help elsewhere, thanks. Unless you
want to run a real OS, Then I'll gladly help you install linux.
