Winch project

360watts at 12v is 30amps. This is your bikes maximum current capability.

What does the winch draw? if its pulling 360watts and pulling the voltage down to say 8 volts, which it quite well could do under a load, this will require 45amps from your charging system.

Your charging system, will not appreciate this and will probably leak magic smoke...

Then all the winch in the world wont help much, its just then more to push home.....

the most i could get the winch to draw was about 7 amps. Even if it was 10A, with lights off (twin 60/55s) i wouldnt have thought there'd be much of a net difference in draw?

Open to further advice on it tho...that said, not planning on doing it again.

this foto shows how steep it is, note Buggs is standing close to rear wheel and handlebar are almost up his head

Next time if you stay on the main track for another minute you'll avoid that chute all together not nearly as steep & ya can leave the winch at home & bike will handle a lot better HaHa

Well 7amps aint much at all! its diddley squat! presuming your amp meter is correct, and im guessing it wont be out by much at all.

Your headlights draw 10amps on high beam.

Do a bit of testing under the highest load you can, even between two cars, your meter will probably only read to 10 amps, so if it goes over use fuses.

Reason i draw caution is i know i would be gutted if i fried my bike and sure you would be too.......

Hell, might as well stay at home next time too!

Yeah ive seen pics of an rd03 burning... i was surprised with the winch draw myself, it fluctuated 3-7A low to medium load. cant recall if that was dragging the bike or not...
