CONTINUITY PROBLEM BETWEEN ALTERNATOR SLIP RINGS AND BRUSHES

View attachment 18772

And this from when you posted earlier in a different thread:

Do you have a service manual? There is a detailed procedure for testing the charging system that is quite good with the exception that the V1 and V2 voltages are labeled incorrectly in some of the manuals. This is easier than checking current as above and should give a good indication of the regulator doing its job.

From that procedure, what kind of voltage do you have on the green wire with the bike not running? Should get 1 to 1.8V, which is a good indication the field coil excitation is correct. On a working system the green wire should go positive to around 9 to 11V with the bike running and the RPM raised to around 2K. The brown wire at the regulator, which receives power from the signal circuit should be close to battery voltage.



If you are disconnecting the stator to do this note that the charging system is running open loop in this mode with the AC generator output disconnected - no voltage to the IC regulator so no feedback. That means maximum AC voltage should be outputted as the IC regulator supplies maximum current to the field coil trying to increase the output. I did not want to rev too high because of the open loop condition.

Idle of about 1100 RPM = 18.5 VAC
Rev to about 2100 RPM = 30.5 VAC

This is measuring phase to phase, and should be equal between any of the 3 wires.

I don't think this is necessarily a problem. The best way to evaluate the field coil would be for current. With the key on (bike not running) and approximately 10V across the field coil you should get a reading of close to 2.5 amps. I just checked mine and it is a working system and I got 2.0 amps, even though the resistance measured was 12 ohms at the connector on my bike. In theory, that would be less than 1 amp, but the 10V applied to the brushes is going to produce a different result - in my case resistance calculates based on current to an actual value of approximately 5 ohms.And this from when you posted earlier in a different thread:Do you have a service manual?
