[Vwdiesel] OT Somewhat--diesel tractor

[Erik Lane]

The times I've seen a problem it has been in a socket where there
wasn't much of anywhere for the grease to escape, and there was a LOT
of it. (If a little is a good idea then a whole bunch is a GREAT idea,
right?) So maybe it was shoving the bottom, spring loaded part of the
socket away from the bulb? Although that wouldn't explain the other
time that I had it blowing fuses. I have no way of knowing, but that
time I assume they just used some random grease that was conducting
the power a little too well.

On the end of a starter it's so flat that I could see it not being
able to be pushed all the way out. But you tighten down those mounting
bolts pretty good so I don't know. How many pounds per square inch
would be needed, or would you need the actual 'wiping' motion of the
bulb being pushed in/turned? You wouldn't get that lateral movement
necessarily when putting in a starter. That was my thinking on it.

I could see it being a problem if the connection wasn't secure.
