I'm trying to figure out the dual sport wiring again, on my custom Honda bike.. '86 XR250R is what the engine block started out as, but its all custom engine and bike from there, bored/stroked XR305cc. I wired it up street legal before, and had things wrong... the battery pack melted and was destroyed. I have some pictures to show and explain, and some (3) basic questions. here is the bike street legal before: coming back together now rebuilt!: stock XR250R wiring diagram from haynes manual: which is basically the same diagram as this: (A/C powers the head and tail light in stock config, no DC system at all) Red circled wires are what I have open from my regulator here, I'm just not sure if its a stock-like AC regulator or actually a DC rectifier...?: Numbers on the side 620403, I couldn't find through quick google search.. That's Question #1, is this device a DC Rectifier or a AC regulator only? I just purchased this (red circled) motorcycle AC regulator: It is just a one wire regulator, Black is ground and the yellow wire is AC positive right? That is my Question #2, how is this wired how can it regulate AC if not inline with an AC hot wire? Do I need this in my setup? On to the last step, I have a Tusk Enduro universal wiring harness that runs all the DC system & battery & ties all the components together: That aftermarket harness could run all DC components separate straight off the battery excluding head/tail still run off AC power, but that way would require plugging the bike into house power every night to float charge the battery. I obviously want my bike wired like a regular enduro, so when the engine is running it is charging the battery with just over 12V DC. So, say I figure out my regulator/rectifier situation to give me DC output.. Question #3: So I wire the rectifier DC +/- output straight to the Tusk harness at the battery +/- connections? Then, what about the Tusk harness yellow/black on/off switch wires at the top of picture? This is on/off for DC components attached to that harness I believe... But I have a 4-wire ignition switch with key, how do I wire this between the bike's stock harness and the aftermarket Tusk harness, so that turning the key off will kill the engine AND cut all DC power/lights at the same time? Wire in key up inline with stock harness' engine kill switch? I'm almost there but I can't for the life of me find straight info or explanations from friends..
