Ok, first of all, I couldn't seem to get a good reading with my crapsman multimeter on my fuel sending unit. I had it set on ohms and the numbers were jumping all over the place no matter where I had the float set. So I set the sending unit on a crossmember, hooked the wires from the truck to it, turned the key on, moved the float to about half tank, and nothing, the gauge reads empty.
Then as I was moving the float it started to feel like it was catching, not moving smoothly and PING, the little arm broke off inside the rheostat ( or whatever it's called ).
So, I either have to try to find a new one, or try to fix this one.
I then tested the (+) wire by turning the key on and using a test light at the sending unit end, and the test light was pulsating - like a directional bulb. Is this right?? I would think it should be a solid light, correct??
Wiring is my weakness, any help would be greatly appreciated. I have a car show a week from tomorrow and I need to get this tank back in and rebuild the carb this week.
Does anyone know where I can find a new sending unit??
