Coil melt down
What would cause a coil to melt completely down?
I was thinking maybe the ignition switch was left on? It got so hot the guts fell out. Thanks for any input. |

Re: Coil melt down
Probably the switch was left on with the points closed.

Re: Coil melt down
Yes, ignition switch left on. (50% chance that it melts)

Re: Coil melt down
Maybe timing with a test light.

Re: Coil melt down
Be Thankful your car didn't catch fire and even burn your garage or house down.

Re: Coil melt down
It wouldnt hurt to open up the junction box, pull back the dash, to check all the wiring..

Re: Coil melt down
I use one of those Pertronix 1.5 ohm epoxy filled coils available from Amazon.
Called a Flamethrower, puts out 40,000 volts. I've left it on with the points closed several times. It got warm but not overly hot. Really a good unit. |

Re: Coil melt down
My repro ignition switch terminal once rubbed on the gas tank and kept the coil on full time. Luckily I just happed to touch the coil and feel it was warm, so I found the problem right away before the coil burned up.
BTW, this is a good reminder to always look at the ammeter when leaving the car to be sure it's on zero. |

Re: Coil melt down
Thanks Guys, that is what I thought happened but wanted your input. I plan on replacing wires and the coils and probably the junction box. I won't know until I get in there.
Isn't the ammeter wired in series with the coil? You would think it would have burned the wiring out of it as small as it is. It made a mess under the hood. |

On the bright side, you know your battery is good!

Re: Coil melt down
True,
And it looks like the battery survived the coil meltdown. |

Re: Coil melt down
I left the ignition ON overnight and it damaged the Pertronix 40611 Coil in my Victoria. As a result, the car is very hard to start, and the engine runs rough at speed. I have a Bosch 00012 Coil on order to replace the Pertronix.

Re: Coil melt down
This is a good point. I had my aftermarket switch connect one of it's terminals to the gas tank behind the dash. Found the coil heating up. Lucky I found it when I did. This problem caused the rig to quit while driving so the reason for working on it. So point being, check you wiring for shorts.

Re: Coil melt down
Always good to look at your ammeter before anything is turned on and then once everything is turned off, to ensure nothing is left on or maybe shorted on... --and a battery cutoff switch is good for peace of mind...
