Re: Pertronix Flame Thrower Coil Installation Question on M/C 470
Terry & Dennis and all else,
I went to the boat today to install my new Flamethrower coil. Before I started I tested the voltage on the old coil with the key on and it read around 8.75 volts. I removed the old coil and installed the Flamethrower, two wires to the negative side four on the positive. The resistor wire which measured the 8.75 volts I cut and taped it off after cutting harness tape it seemed to be pink. I went then to the choke connection that had two wires. After cutting harness tape these two wires were purple and the other was the same pink wire going to the coil that I cut. I went ahead and cut the pink wire at the choke connection. The purple wire to the choke connection measured a little over 12 volts with the key on. I did as Dennis suggested and spliced into the purple wire ahead of the choke connection. When tested the purple wire and my new spliced wire read 12+ volts with the key on but when I connected the choke connector to the choke my voltage drops to 10.14 volts. I don't understand the voltage drop. The boat starts and seems to run fine on muffs but I still do not understand the voltage drop.
PS
I tried eliminating the new spliced wire but the boat would start but quit the moment you released the key from the start position, with the spliced wire connected from the choke wire to the + side of the coil the boat started wnd ran fine after the key was released.
Any thoughts,
Larry
