A fairly accurate amp meter can be built around a good analog sweep meter. All one needs to do is calibrate the swing with a DVM feeding across a length of conductor acting as a shunt. There are plans out there on the net. I have a meter from an old stereo working as one now. I have a mark at the C-20 rate and one at the C-10 rate for my bank.

Here's some links that I had saved in my fav's under panel meters.

Thanks for the help on the panel meters.  I talked to the Yanmar tech that Yanmar referred me to.  No one seems to know just what this PGA engine is.  It was apparently made for a specific application, but they don't know what.  He did say that he didn't think the side load from a serpentine belt running a generator would be a problem.  So, am in the process of trying to find a serpentine belt pulley that I can bolt on the flywheel. 

One of my friends thinks I may get too much variance in the cycles, giving induction motors grief.  He says that when their power is down and he runs his, he watches his Hertz meter and adjusts his RPM accordingly.  Any input on this?  Thanks!

Say Bob,

I'm no electronics genius, but don't I need an AC ammeter?  Or, can one use a DC ammeter by using a diode? Or is that necessary.  (The only ammeter I've got is on a little Lister Petter off of an old light tower.) I'm going to be generating AC with Utterpower's PMG.

Hey all,

Any update on the buildup of this little Yanmar?

I'm seriously considering upgrading from the little Kubota, but I want variable speed control. I suppose I could live with a fixed RPM but that's not what I want. So I suppose I'm asking if the set speed gov was easy to bypass?

Roger are you running 12V or 24V?   What is the max amps that you feel the EB300 is capable> RPM?

Well, max amps @ 12V as best as I can figure WAS 105, more than 2 years ago. That's the last time I pushed it that hard and only for a few seconds. The engine was younger then. It really was belching black smoke and knocking like mad. Not only was I afraid for the little Kubota I know my battery bank, 1,320 AH, didn't need that. I usually max it out at around 35-40 amps these days, and far more often pull 25-30 on a longer run. When I'm using tools or the air conditioner I will run as much as 10 hours straight.
