msd 6al2 it quit firing last night. the led light blinks on the msd unit while turning the motor over but no spark from coil wire I unplug the pickup module wire and the led just stays on so I think the pickup is working fine and I changed coils but maybe both are bad so I have another on the way to try is there anything else to check . need this thing working so I can make to the track tonight to see what this thing will run.

the box.

Go to MSD web site and look at there truoble shooting procedures to figure out what is wrong

Got it fixed, it was the box put an old one I had on the car and now its fixed, voltage gauge also pegs when I up the rpms probly what killed the box so Ive got a new regulater on the way hope that fixes that now. Thanks guys.

My MSD box went bad in the first round at the Sunday race of the Pittsburgh Chrysler Classic. Frustrating, cost me the round and a couple of races the following weeks.
Sent it back to MSD and they said it had a shorted out timing board. Cost $93.00 plus shipping to fix.

new regulater and voltage guage still pegging when I rev the engine about 1800 rpms.

Apparently they are fused inside, has anyone repaired one before.

No fuse inside box , i've repaired a couple of boxes whereby the resister got burnt out , easy fix on those boxes , would have struggled to fix if burnt componant was'nt staring me in the face.
