70D: Intermittent charging/VR question

Not sure of what to check, I checked the ARM post on the generator, and got 7.62 V (fast idle). Resting battery voltage was 6.12 (I thought that a little low).

Any suggestions ? It's a new VR. When it puts out, it's fine, it's just getting it to put out consistently. Also, I don't ever get to run it often or for long periods, so maybe I'll always fight this problem.

Am I chasing an intermittent ground ? Could the VR be set too low ? I took a good ground and touched at the various places, generator case, VR case, checked ground strap. Nothing made the VR jump to charge. If I flick a ground against the ARM lead for less than an instant, it bumps right to charging ( I hope this is not a bad thing).

Any guidance as to what to check. I'm cleaning grounds in the mean time.

I'll work my way down your post and let you know. I did already check for a draw, and found none. I agree that I might not have a problem at all, and that it just takes a bit of time to get that durn VR to kick in.

I'll be sure to draw that battery down some with the lights and then see if it will continue to charge and bring the battery back to nom.

What should the resting voltage be for a 6 v battery ? I was thinking around 6.4 or 6.5.

You know I never get to run it very long, and maybe this is just a thing. Those days when I do get to run it for longer periods it has never refused to work, it's just something I seemed to notice today, and got to wondering.

I know if it was time for it to go planting, I'd never have thought twice.

I'll get back with some test results.

Thanks as always.
