Battery not charging

Post by dstaff »



Took the bike for the first ride of the season.
Noticed the voltage dropping. After a 50Km ride my voltage was down to 9 volts Got home and could not restart the bike after stopping it.
First task this weekend is to replace the old spade connectors for the stator wires with weatherproof ones. (original connector is corroded and shows evidence of burning)

anything else I should look at while I'm at it?

yep, check for burnt connectors around the rectifier, and around the 30 amp fuse and solenoid. you may need to run a stator check also if doesnt charge after fixing the wiring.

good luck,

Replaced Stator connector with a weatherproof one. Still not charging. Replaced 30 amp fuse. Just because it only a $1.30.
Checked Stator with ohm meter. No issues there.

Checked Regutator/Rectifier with ohm meter
Got infinite resistance between Green wire and yellow in the 8 wire harness, and near no resistance between Green and the 2 stand alone yellow wires. Then tested red/white wires and got infinite resistance between all 3 yellow wires.

Time to replace regulator/rectifier.

Did you check the stator is producing AC voltage when the engine is running. You do this by disconnecting the stator wires from the system and checking for AC voltage - should be able to see at least 40 to 50 VAC between any two wire combinations and see it change as you rev the engine.. You should also have no continuity to ground on any stator wire when the engine is not running.

Confirm this then look at the RR.

Hope this helps.

I did check the Stator continuity both with each yellow wire, and then to ground and that was fine.So I assumed all was good with the Stator... But didn’t check the Voltage output.
Also I figured if the R/R failed the continuity test that was good enough to order a new one.

I think this is good news.
Voltages across all three Stator wires are consistently 70v at 3000 rpm.

Looks like I only need to replace the R/R.
I have ordered a Ricks Motorsport R/R. Should be here in a few days.

Nice to see a plan come together.

Success.
Just installed the new Voltage Regulator/ Rectifier. Voltage is now reading a consistent 14 V while riding.
