Hi, I need help finding this part for my HCCT. Is this part needed for testing the coils or is it for the mag in a car? Has any one redone one of these or know someone who does. thank you, any help is welcome. Erick

It would be used for checking on magneto output when hooked up to a car. It could be bypassed and not hooked up if you are just going to use the HCCT to do coils. Seems to me Lang's use to sell a replacement part for this, but for which brand I do not recall. You might call them and ask. Someone might chime in if they can add to this. The single meter (ampere) HCCT I have has the choke(I think that's what it would be called) but is not part of the coil testing.

As far as I know the inductor that is part of the HCCT is wired only into the circuit that tests the magneto on the car and it is not part of the circuit that tests the coil units at the HCCT. To confirm this I have seen a few HCCT that worked fine that i know did not have the inductor in them.

As per John, the inductor is not needed for testing and adjusting coils.
It is only used as a load when testing a magneto on a running car.

Below is the wiring diagram for a typical HCCT.
As can be seen, the inductor in not in play for normal coil testing.

A little further thinking on this ...

The coil can be rebuilt.
It would need to be unwound (count the turns).
The laminations would need to be cleaned and reinsulated.
Then rewind the coil with new wire of the same size.

Thank you all for your input. Erick

There would also be a ground terminal for testing horns and other car magnetos.

Ron Patterson “Coilman” has a source for replacement inductors. I’ve bought a couple of them from him over the years.

OK PDX - Here is the ground terminal. :-)

Thank you Eric, I will talk to Ron.

If your meter artwork is bad, Fun Projects has new scales for that. They come in several sizes and models.
