Re: [Healeys] Ignition Circuit problem

[Bob Spidell <bspidell@comcast.net>]

Didn't see any answers to this, so I'll give it a go.

The ignition circuit only needs 12V (and a ground, of course, usually 
through the points and the plugs).  Open circuits should have no effect 
but, conversely, if there is too much current draw elsewhere it could 
pull the voltage down to where you might have some ignition problems.

The only current going to the coil would pass through your points (or 
electronic ignition if you have one).  If your points are open there 
will be no current to the coil, and if they're closed for a significant 
time--a few minutes perhaps--your coil will overheat.
