Rectifier / Regulator wiring problem

Hi Guys

New to the forum. Bought a 1983 Townmate T80 a while back and have just started working on restoring it. I have a problem with the indicators not flashing and a few other problems but I think that I have located where the problem is.

The battery was fully charged when I put it back on the bike but running the engine for a short while the battery went down to 2.27v. The battery was ok so I think there is a fault with the rectifier. The rectifier plug that the rectifier plugs into looks like it has been altered and I don't think that they have put the wires back in the correct order.
I have tested the rectifier with a multimeter to check the diodes but I'm getting some strange readings.

I have included a simple drawing of the plug that the 3 recifier pins plug into but I need to know if they are in the correct order. I can't find this info anywhere and haynes wiring diagram is no help either.
So could someone check on their bike to confirm that this is correct.
The only reason I can see that would cause the battery to fail is the rectifier, so any help would be appreciated.


Thanks guys
Gary

The wiring appears correct if viewed from rectifier end but on my bike there are 2 red/yellow wires (see pic)
Looks like rectifier/voltage controller is suspect. The table for checking the regulator in the Haynes manual appears wrong as I have checked out several regulators that I have which are known to be OK but fail to give any readings as per the Haynes diagram. Have you checked with a meter to see if there is a battery charge of about 1/2 to 1 amp when engine is running & revved up? Presumably the lights work ok? Also there should not be a discharge (with nothing switched on ie stop light or indicators) There could be a short somewhere else in circuit. If you need a replacement regulator I have one for sale £15 including P&P, let me know & I will PM you my address.
