BINGO!!!: 89 100 Wagon charging system woes :-(

BINGO!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!


DeWitt if you're ever in New England look me up,
I owe you a very large Beer!!!!!!!!!!!  the crimped
connection it is.  And it was very hot as in the 
insulation touching it is burnt.

What do you guy's think about going to the dealer
and demanding they fix this before the dash catches on
fire!!!!

I checked a few things out as in the fuse's all say 12.6.

The cable going into the firewall from the starter say's
14.0.  Which means time to start pulling apart the interior

Pulled the side cover off in the passenger footwell, peeled
the carpet and insulation back, look up almost behind the
heater duct and there is the CRIMP.  Measures 14.0 before
the crimp and 12.6 after.

There you go.

Ok, now how many other people have this same problem :-)

Now you all owe me a beer for not giving up :-)

Now back to the garage and figure out how to fix it, 
usually the easy part :-)  we shall see....

Thanks again everybody,

Mike L.
89 100 Wagon, hopefully fixed tonight!
90 V8, possibly back to it's rightfull owner tomorrow...
