W126 Ground Points

Hey guys,

I am having a few strange problems electrically that I think may be ground issues. For example when the glow plugs start, the wipers come on. It happens religiously! If I turn the key slow enough, sometimes they won't come on. Any pictures or descriptions would be helpful. My intention is to clean and grease all the ground points I can. The negative battery cable is already done. New battery, too.

Seems like I'm trying to play craps in a strip joint and I ain't got any dice. No one knows?

I'd look for a ground on the glow relay. There are also grounds from engine to chassis.....down on the block just above or beside the tranny adapter plate.

The electrical manual has a whole section on ground distribution.
