Have you phased the distributor with the trigger? It couple be firing but just not out the wire you think it is.

1970chevy · 04-21-2009, 05:13 PM

Sounds like the crank triger is shorted somehow,, maybe the pickup is bad? Sorry, but a call to MSD may be your only avenue of real thelp. Oh, havent checked, don't they have a troubleshooting checklist on their site?

I dont know anything about the digital boxes . You do need to phase the dist before you try to fire it though . I use an old cap with a big hole cut out by the #1 plug wire so I dont have to drill a hole in a new one .

Sounds like something in the box is wrong. See if you can borrow another box and try it.

djracer · 04-26-2009, 02:21 AM

what kind of trigger is it? what dist you got. I just put the regular 6al2 in my buddies car and we had trouble with a bad pick up in the dist. do you have an old 87 to 95 chevy truck dist laying around. If you do take the module out and crimp the two wire plug onto the mag pickup wires in the base of the distributor and try using that dist to trigger the box?

1970chevy · 04-26-2009, 11:50 AM

i am running a msd crank trigger 8620 with a programmable box 6530 and pin 84697 dist i look at my dist i have no electric wries out from it i pulled the cap and rotor off and theres nothing under it it sealed with black round thing in their thanks
