My 1st car and I'm in need of a detailed explanation as to how to use a multimeter to trace the ignition as I've no spark at the coil. Coil and amp are new, just need how to trace signal. Perhaps someone knows of a "Dummies" instruction. I've got the Rave and found testing procedures in the Injector Section but it's Greek to me. Also, my Rave features 87,88, 89, & 90 years but the 1990 section doesn't have a test instruction details as robust as the info for the earlier years. In summary by "Dummies" I mean: 1. What setting do I set the meter for? 2. Where to place the + and - at the coil? 3. Etc.? Thanks for reading.
