Electrical System Values & Testing. 750 DOHC

[Jack Dempsey]

Making this new thread as a new member but I'm struggling to find the details when it comes to the charging system and I've found it! But thought many others would have issues finding the information.
This reads from the manual!

Alternator - Three-Phase
Output - 260W at 5000RPM (18Amps min at 5000RPM)

The stator winding resistance between windings should be from 0.41ohms - 0.51 ohms.
This can be checked by going from A - B then A - C then C - B (ABC is just an example all the wires are yellow label them however you'd like).
(Not actually written when it comes to rotor values....)

More information below, I didn't feel like typing it all out but might down the track.

CB750F-A 1980
Stator Windings Resistance Readings.
A-B 1.3 Ohms (Bad)
A-C 0.3 Ohms (Bad)
C-B 0.5 Ohms (Good)
I need values from 0.41 Ohms to 0.5 Ohms.

At 3000RPM Windings AB & C all consistently read values of 0.2VAC.
The Regulator Rectifier had no output value.

Rotor Rings read 0 Ohms and inconsistently go up and down when moving.
Rotor Rings Need to be 4-5 Ohms (I Believe)...

Good source of information, talks a lot of shit but pretty solid info.
