Do you have a "DVOM" (Digital Voltage/Ohm Meter) available to diagnose your problem?
Get a Haynes Manual for the RX-7, as well as take a look at buying a Factory Service manual, if this is your daily driver, the book will SAVE you money in the long run, so it's a heck on an investment. I think Racing Beat might still have a paper version in stock, or if you could just go here:

PS: Even with quite a few knowledgeable people on here, it's still better to look at the factory service manual first to avoid wasting time on simple problems.
