[Vwdiesel] Voltage drop when glowplugs working !

[Mike & Coreen Smith]

Well, I replaced 1 glowplug this morning. I wasn't able to unhook the busbar
on the 2 leftmost glowplugs to test them individually, so did them in
parallel.  My fingers aren't 8" long and 1/4" thick.  How do you guys ever
get that busbar off behind the injector pump anyway?
Sheesh! It's worse than working on my Austin Mini for room back there.
Anyways, I am firing AT LEAST 3 glowplgs now---hopefully 4.

Just for fun I did a voltage check and saw that when the 'plugs are heating,
the voltage in my battery drops to about 9.2volts.   Seems kinda low.....
