Ok. I was out there trying to check dist. timing and hooked the leads up according to manual (neg. clip on neg. battery terminal, pos. clip on alt. bracket ground) and inductive pickup on the # 1 plug wire. I also unplugged the cooling fan. I tried it a few times and light would not flash once. I moved the inductive pickup and still nothing. Plug wires seem to be tight and connections at dist. cap. I have used this before and it has worked fine and I've adjusted timing to factory specs. It is a cheap Actron light if that matters. Please, if you have any tips or suggestions or a similar experience, post here. It's not a desperate matter exactly, this isn't my daily driver, but I intended to figure something out tonight with the car and this is stalling me. Thanks
