Nikita has a hot coil

Hi all, Why does a coil overheat? The coil on the Amphi acted up, the longer
you drove it the worse it ran. That baby was HOT. So I had another used coil
and it worked great for two days. Now that coil has started to act like it is
going to fail. Man it is hot to the touch. I've had this car for years and its
been good so far. This is the car that has been "as cranky as Krushev during a
caviar embargo" lately. Tommy going 55MPH in the Vali IV in Tampa

It's drawing too many amps. I bet you have a short in your ignition
wiring. Try turning on the key without starting the car (press your bilge
blower bypass if you use it)....see if the coil heats up.

Randy,

If you turn on the ignition and then not start the engine, if the
points happen to be closed, even a perfectly good coil will certainly
heat up and perhaps heat to the point of total failure. A coil is
designed to operate with constant opening and closing of the points.
About the only "short" possible in an Amphicar that would heat the
coil up would be a partial short in the coil itself. That can cause
overheating and total failure but your test could "fry" a perfectly
good coil.

Tommy,

You might check the "dwell" of the points. If they are staying
closed too long, it can overheat and damage the coil.

I avoid these problems by replacing the points with a Pertronix
ignition module. No points to adjust or wear, no dwell adjustment,
no side load to the distributor shaft and it's all inside the
distributor. The only thing that shows is a second wire coming out
that goes to the other side of the coil. For appearance sake, I
bundle the two wires together until they reach the coil. It's a
definite winner and not even very expensive. (about $85)

Re: Re: Nikita has a hot coil

Roger that, John. I had this problem with a Model A that had a faulty ignition
switch. Even though the switch looked like it was off, it was still energized
and boy was that coil hot. But that was how we figured there was an energy leak.

Tommy, I agree on the Pertronix. I put one in my Amphi. An easy install and it
works great.

Re: Re: Nikita has a hot coil

I have to second John's opinion on the Pertronix. A great upgrade and it all
fits right under the distributor cap. For the purists out there, another
advantage is that nothing is being modified on the Amphi. You can easily put
the points back in later if you were so inclined.
