I think you're right Danno, moving the r/r further back seems plausible.
Here is my current issue: hooked up to the best of my knowledge, but still not producing more than 12.5v. Should I have the brown line hooked to anything? All I have are the three yellow wires going to the grey connector and the white/red and black going to the black connector. All the connections from Eastern Beaver seemed to go together well and clicked solidly into place. I just don't know... I have the battery on charge but it was good when I fired it up. With a new stator and r/r I'm running out of parts to replace. This battery seems to be doing great but that's all that's left.
