After getting everything back together from my lifter, pushrod, rocker bearings, rocker shafts change over, I go to plug in the two prong connector from my MSD, to the two prong connector from the MSD 6A box, well the purple wire had pulled out from the connector, so I replaced the connector with a two prong trailer type connector. Am I correct in my thinking that the two wires only send a signal "when to fire" to the MSD box?? Reason I ask, I fired the GS up, runs fine, BUT I kept hearing an intermittent "snap" sound, at first I thought it was a loose belt slapping on a pulley, but every time it did it, the engine would shudder. It sounds like its arcing from the distributor cap/wires, coil wire. VERY random. Didn't do this before my connector replacement. Im pretty sure I got the colors right, the purple and green wires from the box, to the orange/black and whatever the other colors were. Im going to run the engine in the dark and see if I can find WHERE it arcing.
the msd is a magnetic pick up. so there shouldnt be any arching there. will run with wires both way will change time about 7*if flopped and the correct way actually depends on box being used
Interesting Ben My arcing (snapping sound) is comming from my cap/wires area, not the two wires I put the new connectors on. But that is interesting about being able to reverse the purple/green wires and it will still run but timing will be off.
Mark, POLARITY is important. If you reverse them, the timing will be very advanced. Very simple, DO NOT connect violet to violet. The magnetic pick up wires are black, one with a violet tracer, the other with an orange tracer. Black/Orange goes to Violet, Black/Violet goes to Green. Check that.
Thanks Larry I will check that! I just wanna make double sure it’s not something I did that’s now causing the random arcing!
