Voltage regulator

That was a test to see if anyone was paying attention....

Thanks for catching me in an alzheimers-moment Greg. I mean, Gary.

(I’ll edit the previous.)

Did your Ebay purchase of a Zeftronic regulator solve your problem?

If so may I suggest that you purchase another Z reg and retain as a spare.

If there is a list of suggested C 170 spare part to keep I don't Know

But a reg would be on the list.

It is part of the mission statement of our type club.

I have a spare automotive unit I keep on-hand ...for “testing” purposes, of course. The $35 lifetime-warranteed AutoZone (Wells) unit has to be carefully inventoried, however, as it is difficult to distinguish from the OEM Delco-Remy, especially if the covers are mixed up by accidnet.

I should get the Zeftronics unit I purchased on eBay by the middle of the week.

Well, I have received and installed the Zeftronics regulator and it solved my charging issue. It starts showing a charge around 1400rpm. Thank you to everyone for your help. The 170 electrical manual was a great help and pointed out the regulator as the issue.
