I am experiencing a problem in that my truck continues to run when I turn the switch off. I pulled the switch and tested the connections and continuity with a multimeter for each position of the key. There was continuity where there was supposed to be and none when there should be none. I replaced the switch then started the truck then turned the switch to "off" and it still kept running. So I measured the voltage still going to the HEI and it was just over 9 volts while the switch was off and the truck still running.
So, obviously 9 volts is enough to keep the coil firing but how is it doing so when the switch shows no continuity in the "off" position?
I disassembled the switch to look inside to see if there were any broken bits inside. There were none and it really looked fine. Before I buy a new switch does anyone have any more troubleshooting recommendations for me. Or is it an obvious problem with the switch? Or is there some other way the voltage is crossing over. I really don't have a complete understanding auto electrical systems but I know this does not make sense to me.
Thanks, Gene
