Wesenberg EVR- voltage cycling problem

[rotorwrench]

There is another outfit that is gearing up to make the EVRs. The started with the model Ts but the change to 6-volt positive ground is not that much of a challenge. Here is a link to a recent post on the subject.

Glad to hear it was a simple fix.

Just FYI, here are photos of Mike Hill's new EVR. One going in a '29 - early '30 generator, the other in a flathead V8 generator. Mike picked up the ball after Tom's passing and makes a very nice EVR. I have installed 6 of them so far, including my own '31 pickup and '35 Fordor V8. They work great.

I had posted earlier about problems with my generator cycling, (is 'all or nothing', no charge for several miles, then full charge for several miles...). And how I was going to revert back from my diode to an original style cutout to see if that fixed it. A local club member directed me to dear sorely-missed Tom's instructions in an old post, to "snip the little blue wire" on the EVR for use with a diode cutout. So, I decided to do that. To my surprise, the little blue wire is already cut!!!

I shouldn't be surprised, Tom installed the EWR for me 13 years ago, and I must have had the diode cutout then. I DID ask him about this cycling issue then (at completion of my restoration), and he assumed it must be because I was using an Optima battery. Recently I switched back to a std battery and still had the problem, thus 'finally time to do something about it'. Now I don't have any idea what to do. I thought about soldering the wire back together and trying a std cutout.... but if the EVR doesn't work as intended now with wire snipped +diode (per Tom's design), why would it be any different with a regular cutout? Thinking I may have to live with the cycling (issue because short drives ending on "no charge" means "low battery voltage" next time I start it). OR, put the 3rd brush back in :-( Any ideas?? Thanks!

You're experiencing charge cycling issues with your Tom Wesenberg EVR and have tried various solutions, like reverting to an original cutout or snipping the blue wire, but the problem persists, and you're seeking advice on how to resolve it.
