So I have bought a new regulator and new rectifier.
REGULATOR-
I tried the tests for 12v on the regulator wires (brown green and indirectly black) and those were good
but the resistance between the brown and green wires were 500ohms on my new one and about 1,200ohms on my old one. (the manual test says that it should be around 140ohms +/- 10ohms)
Furthermore, when I did the test of attaching the green wire from the stator to the battery positive directly, the battery started charging really well (13v-14.5+volts)
STATOR-
The stator reads 1.5ohms across the 3 white wires but when accounting for the charge on the leads of the multimeter (.7/.8), the stator wires seem to be testing at .7/.8 which is exactly what I want
FIELD COIL-
The magnetism is present once I attach the green wire to the battery positive directly. Thus I think this is also good
BATTERY-
my battery is currently at 12.8V and therefore that could be bad but I imagine that it should still charge regardless.
Did I just get another faulty regulator? and do I just need to buy another one?
Is there any other part that could be bad? Could it be bad wiring?
I know this is yet another charging system question that has been answered a billion times. I've read all of the threads on this matter but I would like to know if anyone has any experience on this and if the 140ohm test on the green and brown wires of the regulator is the right test.
I've considered buying the r292 regulator but it seems like people have mixed reviews on this.
My bike is a 80/81 SOHC by the way
