Dug into the missing high beam today and here's what I found:

- grounds on both sides appear OK. Tested left high-beam on right ground and OK, left on right + fails.
- removed all wired from the plugs and inspected. Look OK
- voltmeter shows 12v on left side, and that or slightly higher on the right (why would it be higher??)
- meter I have can't check amps so I'm sidelined until I can get one.

This van is completely stock - if the problem isn't the wired themselves, would a relay kit have any effect? I'm planning to install one anyway, but would do it sooner if it would help.
