I was tinkering around this weekend trying to isolate the handheld brake light problem I HAD. I turned the ignition on (engine off) and was working the issue. I accidently left the ignition in the on position for about 20 minutes. When I returned to the engine bay and was working on some wire connectors I accidently touched the coil with my hand and it was HOT - very hot.
Can someone tell me if that is normal, or if I should be concerned about anything in particular. thanks, (IMG:http://www.914world.com/bbs2/html/emoticons/blink.gif) |

Whenever I work on my car with the ignition on I always disconnect the coil.
If the points in the distributor are closed when the ignition is on (engine off) the coil is getting power and will heat up. I also heard somewhere that this could lead to damage to the wiring harness if the ignition is left on too long and the points are closed. |

It can damage your points and will kill a pertronix.

That happened to me once. Something really weird happened. it didn't damage anything but out of no where it blew up. No one else had ever heard of this happening but just watch out. It got really hot before it happened.

If you leave the ignition on, with the points closed, the coil will (over) heat to a point where it will explode.....................
And, if you have a VW Bus (early split-window), the coil is aimed right at the gas line from the tank....the hot wires will melt the fuel line, ignite the fuel (which you won't be able to put out) and the fire will eventually get hot enough to start the mag engine case on fire (which you won't put out) and the Forest Service Fire Truck will eventually arrive and they will protect everything from your buring van and after it is all over will tell you that you have a really big tax write off that year. |
