Hi Guys!
I am struggling here with the electric system of Herman (my 1991 Maxi Van). Can anyone provide me some schematics featuring this model and year?
I am also interested in 'schematics' of the vacuum-system, with is still sort of mysterious to me :-)

I have a Workshop-manual, but that's incomplete and the 1991 is just mentioned in the appendix.

The problem ist, as soon as i switch the ignition on, the power drops immediately to 2-3 volts inside the car. I measured the battery - strong 12,6v and good for some starts. The pre-owner left kind of a battlefield underneath the dashbord to convert it to german light- and turnsignal-standards.
Greetz from overseas,
Andy

 

Get a factory service manual. Published by Bishko. (I think) You can usually find them on Ebay, or similar sites. Paper manuals are expensive, the DVD or digital download versions are pretty cheap.
