So, as stated earlier, my '77 Fiat 124 Spider stalled on the freeway at about 70 mph and would only start and run briefly, if it would start at all. After much testing, I thought I had it figured out; the Fireball XR700
optical trigger failed to light, indicating the pick-up or module was bad. I confirmed this test and diagnosis with a tech at "Fast," the company that bought out Fireball from Crane Cam. I have installed the new module and
pick-up (optical trigger) and tested it to make sure it works. Now, the car starts right up, but the battery charge indicator light in the instrument cluster isn't lit when the key is in the "on" position and comes on after the car
has run for just a moment and the car then immediately stalls out. Any suggestions or insight?
