What is causing my new setup to squeal? I did the teamrush and everything has run fine. Yesterday I finished my grounding. When I turned the switch on, I got this weird high pitched squeal coming from the coil I think. It is a junkyard coil but it didn't give me any problems before I put in all my grounds.
Need major input now. I checked the "squealing coil" earlier today and with the ignition switch on/engine NOT running, my coil wire had "fire"...I know because it shocked the crap out of me.
so, I took the jeep for a ride down the road. After a few miles it began to lose power, backfired a couple of times and went dead. It would crank but was struggling, fighting the starter, like a timing issue. I could get it to run for a few seconds, it would start 'loping' then backfire and die. I've also noticed that my squeal in the coil is now gone...it also is no longer "hot" like it was when squealing. Took the distrib cap off and the new rotor is charred just a little.
If my coil was shot, would it even crank? Have I jacked my timing somehow?
I had that happen to me once and it turned out to be a problem with low battery voltage somehow. It went away when I charged up the battery but I'm not sure it that was the cure or redoing all my grounds at the same time fixed it. I wasn't consintrating on the noise at the time.
Do you have a condenser, mounted to the side of the coil? Typically these are used for filtering out noise to the radio and in older vehicles with point type ignition system it prevents the points from arcing and prevents coil insulation breakdown by limiting the rate of voltage rise at the points. . All that said they will squeal and if they go bad, (shorts out to ground), it will cause issues. if you have one, disconnect it and see if the problem goes away.
I didn't see the 'U Tube' video, can't get it to load,
But if the coil is cycling before the engine cranks, you have the trigger wires and coil wires bundled together and INDUCTION is triggering the coil in a feedback loop before you even start the engine.
Trigger wires should be twisted around each other,
And should NEVER be bundled with the coil feed wires or the high voltage wires.
These wires trigger on as little as 0.2 volt, which is easily produced by induction from the coil feed wires if the wires are bundled together.
