but on a side note someone could have wired it in for the ignition , gotta follow the wires
As I said before, find the power on wire for the Sniper and power the MSD from the same wire as it's obviously powered in crank and run, neither unit draws power from it they simply get their turn-on signal from it.I cleaned the terminals on the ballast-didnt fix.I bought a new one for $8 just to eliminate it..didn't fix
When you jump the relay, the key is still in run, not start. It sounds like you are loosing power to the ign circuit when starting, which is the normal way for the 70's ign switches to work. It took me quite a bit to track this down when I installed HEI dizzys in my 77. If you just tie the two circuits together, you will have intermittent episodes of the starter not turning off. Because power is backfeeding, and keeping the relay energized. I solved it by using a relay in parallel to the starter relay to give the standard ign bypass circuit on one truck, and by using 80's relays on the others. They call it the Bal terminal.Thanks SuperBurban..I understand what you said but am still confused..I'm not sure the PO wired the original MSD correctly as I still have a ballast resistor in the mix..per Dodgeboys I shouldn't have one. That being said it has run fine for the last year or so with the new ign box and sniper..can't figure out why it won't start with the key but will off of the solenoid. Sniper says that the RPM should show the engine speed while cranking which indicates correct ign hookup(power at coil)..if it doesn't, mine doesn't, its because there's no power to the ign..when I jump the solenoid it shows RPM and fires. I'm clearly missing something.. probably something dumb.
