Yes, what it does is the pulse changes polarity (if it goes first neg, then pos, it flops with the pos first and neg last) Only one polarity of the complete pulse triggers the box so if it flips this changes the timing in relation to the pickup and the contacts in the cap, so the spark "moves over" and fires BETWEEN the cap contacts
There is a YouTube movie or two about this....... Just be aware, and if it runs rough, "suspect." The MSD video talks about an adjustable rotor. In this case we are only talking abour reversing the pickup wires
Hey man wanted to thank you! Install went great. When I went to start it up... crossfiring... Knew exactly what it was, flipped the distributor wires and BOOM, running better than ever. Appreciate your advice!
