as for quincy, check these guys out. Or check my other link after. I once hooked up a kickstarter kit like that on a old devilbiss 3hp single phase, worked like a charm. Might be worth a look.


The kick start kit is usa , houston I think.

anyway here is a link.

The Quincy air compressor is located and wired up now. I had to buy a new (5 hp) motor for it. It is a very quiet unit, but won't run that often. With a 120 gal tank charged to 175 psi, I should have "unlimited" air now. I still need to run some air lines around my shop/garage.

Back in December it was decided that the generator going back to my friend (going to his nephew, actually) would get a new VR. The order had some difficulties and ended up costing $$$, but I got it a week ago. With the new VR installed, I ran my shop on the generator for a couple of hours and now have it sitting waiting to be picked-up. I may go along on the delivery to help get it connected and convey all knowledge I have gained.

The other generator, the one I am keeping, has been re-wired considerably to bypass the inop control board and just generally simplify the unit. I still have no VR for it, but am working on developing my own design. The heart of the VR needs to be a "buck" SMPS (switch-mode power-supply), and that is challenging me. However, what I am learning would be useful to me if I ever get an old Bolt EV and need to replace/revise the motor controller stuff.

Billr, as usual, you are an inspiration.


and that is challenging me

Honestly, I don't think anything challenges you. That is a compliment BTW. ;)

I have no idea what a "buck" SMPS is. Maybe I am just not getting the acronyms. My mind want to go to BMS. in a bolt, the bms (battery management system) relays on a step up and step down system to avoid arcing of the main relays.

So, if in case I am in left field on this one, plz correct me, I am most willing, as my arse is on the line for compensation, and I really NEED to understand this concept.

Yes, that Wikipedia article describes what I am talking about.
