Yeah, I know; this is a truck/SUV site. However, since in the past I've received such good and reasonably prompt replies, I thought I'd at least try here and, if no one had any ideas, I could be directed to a site that'd have the information?

I'm working on an '82 Mustang and I'm looking for information such as:
1.) is there a ballast resistor that connects the coil to the 12V supply and
2.) I'm looking for information as to how to troubleshoot the tachometer.


A wiring diagram would help in solving both questions.
