Hey guys... Car was running fine one minute, parked it for a few days, now no spark. The car has a summit racing digital ignition box, then it connects to a msd blaster ss. I used a volt meter and determined the blaster ss is not getting any power. So i know it has to be something to do with the ignition box. Is there anyway to test if it has gone bad? Thanks

it probably has an internal fuse

Yeah i was looking at it, but it didnt seem like it was meant to come open to easy. But i will try and take it apart tonight. Only thing i saw right away is a small plate it has that you take off to adjust the rev limit and what size engine you have.

Unplug box plug everything as was before installation of box. Plugs are by the coil.

I will look it over, but i believe it just has alot of wires spliced into it. I did not install this ignition box, the car came with it installed when i bought it so im a little in the dark on the whole thing.

I don't think that is going to work with a carb car.

You need to find a diagram of the way it is wired up so it can be tested.

Unplug harness at coil now follow back about 10" and unplug connector. Notice it looks like plug just taken off coil. Plug that end into coil. Done. Most folks buy this or comes with box. Ignition box is now defeated.

Hey guys just swapped it out with a new igniton box from summit, car is going good again ... One new problem came up, now the car wants to idle very low and when driving it will die when im downshifting or slowing down using the clutch. Should i just turn play with the distributer a little or what do you guys think? Something to do with the new ignition system im sure.

Tried to adjust the distributer and got it running about 100rpm higher. But it still needs to go up some, think i need to play with my carb?
