Stator/magneto?

[cid]

So I have a new battery and the thing doesnt drain when off but it seems it's not being charged whilst I'm using the bike. 1986 gs550l. What is the fix for this. Is it difficult and where can I find the part?

Could be stator, could be R/R, you will need to read through the stator papers to better understand how the charging system works, then go through the fault finding chart and report back what your test results are.

Good advise there, but you should have already checked and cleaned your wiring harness connections - this will give you clues to where the problem may lie

Quick check.

Disconnect the three yellow stator wires. Check the AC voltage between each two wires (1,2) (1,3) (2,3) with the engine at 5k rpm. You should read 80v AC on your multimeter. If you get that or close to it, the stator is working fine. Connect the stator yellow leads to the three yellow AC input leads on the R/R and connect the black 12v DC negative output lead on the R/R to battery negative and the red 12v DC positive output lead on the R/R to battery positive. Start the bike and with your multimeter set to 20vDC check voltage at the battery with the bike running at about 3k rpm and the headlight on. You should see something in the 14 to no more than 14.8 volt range. If you're getting voltage above that range, or below, the R/R is faulty.
