Thanks - that was my thinking completely. I already erplaced my regulator with a $12 one from ebay. Seems to work fine for the moment, though far fewer cooling fins heat sink. I will watch it. Besides the low voltage another symptom of the old bad regulator was that the junction connector with the wiring had one of the three prongs melted through the plastic casing. Obviously an electrical problem somewhere.

BMS 250CC "MACHOMAN" - I am replacing the voltage regulator because I am not getting enough voltage to charge the battery properly - 13.5 to 14 volts at the battery. I have checked the stator and am getting 50 volts or better at the output so I believe that the stator is good.
The regulator is 6 wire. One of the 3 outputs from the stator has a wire hooked to it that leads independently to the carburetor. Looking at the wiring diagrams it seems to run initially to something called a "liquid adding valve," as so identified on the diagrams. Anybody know what this is? It apparently runs completely from the raw stator power, i.e., AC current at around 50 volts.

Question - my scooter is a BMS JMSTAR CF250, a Honda Reflex clone. My temp gauge has 3 connectors but only 2 wires go to it. There are no lights inside it. Recently I had to oil the speedo and took out the instrument panel. Speedo is good now - no noise. But the engine temp is now reading very high on the gauge and goes up much more quickly than before. Is it possible that the gauge wires are selectable? That one connector is for a certain voltage and another for a different voltage, based on what temperature sensor is installed? I actually put in a new thermostat just in case and no real change. Years ago I had an overheating problem that finally cured itself so I thought maybe it would be a good idea to change the thermostat.
I don't think I am crazy - there are 3 possible connections and only 2 wires. No. I haven't tried switching yet as I would have to take apart the windshield, etc.
Anyway, any thoughts out there?
