I found this site while googling for a possible fix...so I joined! I installed a petronix ignitor lll and a flame thrower lll yesterday on my 71 Mach1, runs great but tac now not working, also tempature gauge appears not to be working correctly, it now barely moves where it normally ran in the middle range prior to installing the Petronix. I followed the instructions that came with the parts which called for a 12V positive wire to be added to the coil from the fuse box and disconnected the resistor wire that was connected to the coil. The ignitor lll and flame thrower lll need a full 12V at all times, while the resistor wire only provided 12V at start up then cut back to approximately 8V to spare the points (as I understand it?).
Note: Yes the wire I added works with the ignition just as the resistor wire does and is off when engine is shut down.
I take it disconnecting the resistor wire from coil is the issue with my tac now not working (wiring shows resistor wire to coil came from Tac). My question is, can I reconnect the resistor wire back to the coil (positive side) in addition to the full 12V wire I ran from my fuze box...or is this going to cause issues
Any advice would be appreciate, sorry if i posted this in the wrong area...I'm a newbie.
