Re: Gas gauge - is this right?
Ok, I'm still running 6V. The issue I'm having is that when the tank is more than 5/8 full the needle is disappearing off the gauge way past full. Bending the float arm isn't going to correct that. I've found that my charging rate is set a bit on the high side, 7.6V. I've also since found that the gauge operates by means of a small heater that warms a bimetallic strip to cause the needle deflection, so I answered my own original question, 5W of power dissipation probably isn't off the mark. Given my slightly high system voltage (that I'm planning to leave alone since it helps headlight brightness) inserting a resistor into the sending unit line will in fact fix my issue, it just needs to be rated appropriately.
