Way to test optispark and optical sensor?
I have a 94 Camaro LT1 A4 transmission, I'm pretty sure my optispark is shot....again, but before I bring it to a shop so they can have it for a month before they even figure out the problem....again, I was wondering if I could test the opti and the optical sensor myself?
I tested the ICM using the instructions at shbox.com, it said dc volts I should be getting 10 on terminal A and D, I got 11.19 volts on both, I figured that might be fine. On AC volts testing terminal B I should get between 1-4 volts, I got roughly around 2.8-4 but at one point it shot up to 8 volts. I know the voltage in my battery is low but I think I got some clear readings.
So is there a way to test the opti and sensor? I see everywhere problems with bad opti, but is there a way to test it? Is 8 AC volts to much, and or could my battery be giving me false readings?
