Vintage owners - I need you help in identifiying a wire and its contact point.
After removing the blue Bosch coil from my car with all the other wires attached, I found a black wire with a spade terminal that looked like it ran to the coil.
The car starts and runs, but the speedometer is a bit whacky so I was thinking there was a correlation. It either connects to the (+) or the (-) terminal on the coil - I just dont know which one.
Any ideas?
Thanks, Brad

There is a wire from your coil to your tachometer, does your tach work ok ?
Tach is OK, but I am now thinking there is a loose connection on the back of the speedometer that is causing the speedo issue.
Still need to figure out what that black wire connects to.
Unless you have fancy electronic speedo - it should be mechanical via cable. The original VW T1 wiring had the backup lights powered off the coil with an in line fuse. It could be for the automatic choke/solenoid if you still have a the OEM single carb (it was a black wire). There is a VS wiring harness diagram posted in the library for donating members. Black is normally ground (but don't ground it without checking for voltage).

A whacky mechanical speedo is caused by an ungreased cable, a sharp bend in cable, a missing wheel C clip or a Chinese Speedo.
