My son got the pma and regulator from Hugh. We wired it up (correctly). I pretty much solder, crimp, and shrink wrap everything. We put on 2 tiny batteries the size of a cigarette pack. They are 0.8 amps each, for a total of 1.6 amps. The bike would start, but run like absolute crap, even at higher rpms. We couldn't get decent voltage readings across the batteries either. While messing with it we ran little jumpers to a small battery off to the side and it all straightened out. He ditched the batteries and we went with a small battery of 8.0 amps. Everything is peachy now. 14.59 across the battery, runs great, battery came back from our run fully charged. I've noticed a lot of guys having problems trying to use capacitors & such. Our little batteries, of which one should have been enough, were not up to it. They test out OK. I find it odd that the pma was worthless even at speed until we went to more battery. There are certainly no substandard or inadequate connections. With just a bit more battery....golden.
