GS750 Charging system….I hate them!

[Adi00]

Hi guys,
Can’t seem to find the charging system article done by Basecliff anymore, can someone remind me where it is please?

I have rebuilt my GS750 1977, full strip and rebuild of carbs etc and it starts on the button better than any GS I have ever owned. Happy days on that level.

However, battery shows 12.60 volts before starting and stays the same after starting at any revs so assuming it is not charging.

Firstly, I must say, I hate electrics!

I have an after market stator and reg/rec.

Continuity from each of the stator yellow wires / windings shows there is no grounding.

Ohms Resistance from each of the stator yellow wires strangely shows 1.6 and the manual states it should be 0.65 +/-0.05.

i assume my stator is dead?

Can anyone give me a pointer?

Many thanks

Adi.

Put the voltmeter on AC
Disconnect the stator wire connections, start the engine and test between any 2 of the 3 wires
Rev to 4k, it should show at least 70 V AC between all 3 pairs

Thanks BigT, will give it a try tomorrow.

How many poles does the stator have ?. Early stators are 12 pole, if an 18 pole stator is fitted to an early flywheel it probably won't work correctly.

I haven’t had the stator out so not sure how many poles. Will have to check. Thanks mate.

The early systems are 12 pole. The stator type and rotor must match, otherwise, it doesn't matter. Both work with a modern SH775 R/R.
