coil question

alright im working on a old miller welder/generator with a onan motor. now i may be loosing it but i clean up point and now have them moving and working. but i have power on both sides of coil. it seems every coil i have in the garage has continuity between posts. hmmm are they junk? im having a brain fart here.point and pulsing ground so i know they are working. no damaged wiring hmmm thoughts?

That may be the most confusing post ever. Were you drinking while you worked on it??


The coil should have power to the plus side. The negative side should go to the distributor side (at least in a vehicle).

This is how a car motor works, I don't know about your Onan. Is it a 2 cylinder?

There are two sets of windings inside of a coil. A primary and secondary. You check them by the resistance between the terminals and between the terminals and the distributor connection. You would need the values of your coil.

In most cars, the readings would be around .8 Ohms between terminals and around 10,000 Ohms between the terminals and the distributor connection.

I hope that helps you with your project..

If I think I understand what you think your trying to say....your reading a positive voltage on both sides of the coil? that would mean that side of the coil is good...check the grounds (make sure the points are closed when your testing that, an open circuit in the ground side will show a pos. voltage on both sides)

if everything looks good then, suspect the coil...or make things easy and just stick another known good one on to test it...much quicker and easier that way...
