Best way to test my Dynamo?

Took off the E3LM as I am still facing charging problems.
Today I noticed zero charging with the terminals connection method. So now it is extracted from its magneto seat, and I would like to know the simplest way of how to test it. I measured a resistant of 2,9 Ohms on the field but unfortunately can't remember the reading resistance of the Dynamo winding, silly me
BTW, I will have access to a lathe end of next week and am ready to wait, if you guys will say that it is the better way to go.
Thanks – Michael.

Re: Best way to test my Dynamo?

You can do a basic test. Lay the dynamo on your bench/top of vice. Wind the D&F wires together and connect them to the positive side of a 6V battery. Now earth the dynamo body to the Neg side of battery. The dynamo should motor in the same direction as the drive arrow. Ron

Ron,
can you do this also with a battery charger instead of a battery ?
Or doesn't that work ?

I've never tried that Michel Ron

Not usually unless it is a very heavy duty battery charger
However connected to a battery, even a bad one should work.
Or you can use a 12 V battery with a heavy load like a pair of headlamp globes ins series
