[Vwdiesel] Starting issues 91 Jetta TD (Fancy Dancer)

[DAN SNYDER]

If the fan was blowing UNTIL you moved the key to the "start" position, that means that a small amount of juice could flow, but when you engaged the starter, then almost all of the juice available flowed (flew?) through the starter motor, and there wasn't enough left to run the fan. 

IF this is what really happened, then you could have a high resistance connection to the battery. Check the battery terminals, and then where the ground strap attaches, and then the hot lead to the starter motor. 

Just my 2¢
