Hi!
Rebuild my bike 4 years ago, always ran great until now. It's not charging and I could really use some help. Running the bike >2000 RPM results in 12,0 V.
I have red multiple topics on this forum trying to solve it, but no luck so far. Below a summary of the things I have tried/tested:
My bike: a mix of custom and stock parts. The wiring loom is not original but based on one i found here. Kick start only. Stock electronic ignition. Smaller battery.
Battery (aftermarket 4Ah):
- 11,8 V after barely making it home.
- Charged it to 13,5V. This slowly reduced to a stable 12,8V
- burned a bulb for an hour: battery remains at 12,8V (OK)
- Battery is keeping its charge of 12,8V for 2 weeks now (OK)
Brushes:
- slabtest: OK
- Voltage at the positive brush: 12,7 V (OK)
- Brush length: OK
- Measured from brush to ground: 1st brush: 8,8 Ohm. 2nd brush: 17,2 Ohm. Manual does not state anything. I do notice the big difference. (OK/NOK?)
Rotor (Stock):
- Slipring-slipring resistance: 5,5 Ohm (OK)
- either slipring - ground: ∞ (OK)
Stator (Stock):
- Resistance from White - white (3x) measured from connector: 0.8 Ohm (manual:0,46 Ohm). Please note that my connector is further away that on the stock wiring loom. (OK/NOK?)
- Yellow wire: removed from day one.
- Measured V ac at the white wires with connector plugged in @ idle : 3x around 13,4 Vac. (OK/NOK?)
Rectifier/regulator (Stock):
- Measured it according manual: OK
- colleague from work re-measured it: OK
Today i used my brand new car battery to check if it charges with that. Car battery: 12,5 V. Running the bike >2000 RPM: 12,0 V. This does rule out my motorcycle battery.
Anyways, electrics is not my strong point and im kind of lost here. Could someone point me in the right direction?
