90 200tq 10v - Total loss of electrical power

[Brian K. Ullrich]

Hey guys,

 

Update on my '90 200tq project. I got everything back together underside and
the car is tight. Runs well, but has a weird buck at 1.7bar. Also, seems to
idle a little rough and probably rich as it failed an emissions test this
morning. All that is minor right now.

 

The REAL head-scratcher is that on the way back from the inspection station,
I stopped at a convenience store, and when I came back out, there was no
electrical power in the car at all. Turned the key; nothing. No accessory
power, no lights, nada. It is like there is no battery in the car.

 

So, the car is stuck at the store, my shop manuals are behind locked doors
at the wrench's shop, and I'm stumped. Any ideas?
