Just removed all accessories from my '00 VFR, alarm, gear indicator, heated grips etc and then soldered earths together and hooked to frame. (crappy alarm that failed, plus earth faults plus there was a contentious black wire from the RR (that i took to be an earth) soldered onto my fuel injection circuit below the fuse box) . Charging circuit showed normal before i drove out. Everything worked fine. But then the bike burned out a new yuasa battery in 238 miles. With smoke coming from battery terminals and bike stinking of hydrogen the multimeter still gave a normal 14ish volt readout with the motor running. i was expecting to confirm a fried RR unit (ie 17 or 18V). This is a new one to me. Every cooked battery i ever saw till now was cooked by a bad RR. Anybody seen this before? Or does anybody know where the black wire from the RR goes to even......

I don't know about the 5th gen R/R's, but if they're like the 6th gen, I can tell you. The 6th gen has 3 yellow stator inputs, 2 red positive output, 2 green grounds (or earths, as you call them), and a thin black wire. That black wire is a monitor wire, which is normally connected to a positive line or straight to the positive terminal of the battery, and controls the voltage that the R/R puts out. By grounding it, if that's what you did, you basically wired the R/R to output all the voltage the stator made, without any regulation. If that's the case, I'm not surprised the battery got smoked, but I wonder how it even ran that way and/or didn't totally fry the wiring and everything else.
thanks, cheers, endebted Muchisimas gracias! Have been trying to repair loom after removing an in correctly wired alarm. The poxbottle wired that as an earth, engine off it tests that way. New reg rec and out we go.....
