Alternator charge light

I have a Powermaster alternator which is now wired up as a one wire which works fine. I have read many posts to see how to correctly wire it up three wire. One post in particular was very good and showed exactly what I was after. It said to jumper the two outside connectors of the old external regulator together and jumper the two inside ones together. Then a wire should be run from the blue wire terminal on this connector to the No.1 terminal on the alternator (the one closest to the battery charge post if they're not labled). The other wire would run from the white wire terminal on the VR connector to the No.2 terminal on the alternator. These are for sense and the charge/gen light. I wired mine up like this and it sort of works. When I go to start the engine, the gen light goes out when it is winding over but when the engine fires it comes back on bright. Thought I made a mistake with the wiring but after doing a few checks, I'm thinking the wiring may be correct. The voltage of the wire coming from the gen light (at the old VR connector is only 8.8volts and when the engine is running, the voltage at the No.1 terminal of the alternator is 14.4 volts. Could this voltage difference cause the gen light to act like this? I realise 8.8volts is a fairly big drop and there must be a bad connection somewhere. I will endeavour to track it down. I'm far from an expert on this so thought I would put it to you guys.
Thanks in advance for your help.
