I tested the dyno-prop today. I had been waiting to complete some rework on the Harly-Davidson generator I'm using. I was trying to pass control back to the pilot by putting a solid-state relay inline with the regulator's output. The relay appears to have either interfered with the proper operation of the regulator, or caused enough of a voltage drop to make the generator unable to charge the battery. Either way, the relay is out, and a 80A fusible link is in. I'm now getting 13.5V at 4000rpm.

Hi Earnest,
13.5 V sounds a bit low, unless the regulator is holding voltage artificially low. Isn't the HD generator designed for direct drive off the HD crank? If so, I'd think that it could make useful voltage & current at much lower rpm (think city riding in traffic).
I had some starting issues, so the battery was run down a bit. The voltage was still climbing when I had to shut it down due to the heat. The regulator should bring it up to 14.25V eventually.
