Engine starting issues on the road...
Engine starting issues on the road...
Had to encounter starting issues last Sunday during a ride out from our club.
After a stop I had too low voltage in the battery (12.2V) to get the starter engine engaged.
Jump started with the help of a nice gentleman living where I was stranded,
Charging voltage at the battery with the engine running showed 12,5 volts only.
As a precaution to prevent the battery from draining I removed the lights fuse and headed home.
Got home (100km) without stopping and having had any issue.
I just performed the stator check (by the Dyna Models Electrical Diagnostic Manual)
1. Turned ignition switch OFF.
2. Connected the ohmmeter.
a. Disconnected voltage regulator connector from alternator stator wiring.
b. Inserted one ohmmeter lead into a stator connector socket.
c. Attached the other lead to a suitable ground.
3. Tested for continuity with ohmmeter set to the ohms scale.
a. A good stator will show no continuity (open circuit) between any stator sockets and ground.
b. Any other reading indicates a grounded stator which must be replaced.
Reading results: 1.0 and 1.0 ohm = grounded stator!
4. Removed ground lead. Checked resistance across stator sockets 1-2
5. Tested for resistance with ohmmeter set on the ohms scale.
a. Resistance across all the stator sockets should be 0.1-0.2 ohms.
b. If the resistance is higher, the stator is damaged and must be replaced.
c. If the resistance is lower, it could indicate turn to turn short.
Reading results: 0.4 ohm = damaged stator!
Overall conclusion:
Stator is grounded & damaged and needs to be replaced!

If you can get Cycle Electric overseas that would be my first choice in replacement parts. Go with the stator , you now know it's bad and get C/E's rectifier/regulator. I installed a C/E reg. in 2007 on my 02 Dyna and it's still hanging in there.
Only after having opened the primary cover last week...
