Wilesco dynamo
« on: October 30, 2020, 04:14:56 pm »
I bought a Wilesco dynamo,the one for the d32 off ebay. Well got it today and it has no output at all. Has anyone had one apart and what to look for ? Thanks for any help you can give me.

I don´t know which specific type you´re referring to Brian, as i´ve seen most types of Wilesco generators mounted on a D32, and at least 2 that i´d consider dedicated D32 generators.

My initial suspicions would be:
Poor magnets
Wornout brushes.
Overlubrication (which will yield poor contact if the commutator gets oiled as well).
Burned out coils (since that they all can run as motors as well, but easily see to high voltage or load).

Does the dynamo run, when you serve it som low voltage?
If it rotates at 2-4 volts everything should be good inside electrically, but if you have to lift the voltage much higher to get it to turn over, weak magnets would be my suspect.

I have the maroon bakelite version and it stopped working,took it apart and found the rotating middle section
had come loose on the shaft,just needed some loctite and worked fine again.
Hope that helps,
Trevor.

Then there´s little reason to theorize further, and just enjoy that nice addition instead...

Well done!  :)

That's fantastic,  oft times it's just the desire to be willing to delve  into a problem further to get a nice outcome.
