Thanks Gents, that part I get, but is let's say it (the gas float assy) is working, and it's the bulb that's out. Or, let's say it's not working and the bulb is out too. I'd like to test both separate and independent of each other.
To get the light to light up, which wires get shorted? Also, and this I can't remember even though I should... In what operation condition does the light come on when everything is working, and there is a low-fuel condition, i.e. key switched on/kill switch off, or, key switched on/kill switch on? Have to be running (like the fuel pump)?
