I bought a 12VDC Moose regulator for $15 and found the manufacturer. The problem is that they don't say how much power it can dissipate, like a wattage number. It's a two wire regulator, that's supposed to be connected parallel to the lighting coil, bolted to the frame to help dissipate heat.
I was checking thier website and found a good page on voltage rectification/regulation. I want to share with the group.

Oh, by the way, I tried to get some of that Stablitant ?22A from NAPA and they want $65 for a 15mL bottle.... ? :o
I just read the page and they are talking about lower power systems than ours. The series and shunt regulators they refer to are for under 100W generators. Ours are 300W. They explain theory well enough though.
check for the stabilant in stereo shops too,, they sell it a lot cheaper, but is same stuff, can also check local hacker shack(computer shop ) they use it a lot
