If it's just a popped resistor, see if one of your MSD buddies can take their similar unit apart and get you the values. The fix shouldn't be too difficult.
well since this is the only rig I have thats legal (trucks tags are expired) I saw this as a time to upgrade, went to a digital 6AL, and picked up some spiral-core 8mm wires. This roasted box is pushing 8 years old and im really not torqued about it dying, mostly irked about when it died haha I ran this box in 3 different rigs. As for the resistor values i do have an extra OLD 6A that had a slight misfire at idle, i could rip it down to see whats what and play mad-scientist. hehehehe
