Trying to replace the fuel gauge on a gas 641. I bought a gauge and sending unit from Dennis Carpender. There are no instructions with the gauge. The gauge has three terminals. One marked "B" one "T" and the third "6 volt". I have a six volt postive ground system. I have the "T" terminal connected to the sender. The "B" connected to the key switch. I called dennis and was told to ground the terminal marked "six volts" so I did.
The gauge needle does not move unless I unplug the wire to the sender unit. Then the needle will move off of Empty and stop at 3/4 mark.
I have hooked the sending unit to my Ohm meter and the unit works when I move the float up and down.
I'm I wrong thinking the gauge has a problem?
I have put fuel gauges in two 12 volt conversions a 62 4000 and another 641. They both worked fine.
