The sending unit has a variable resistance element and a contact switch . The contact switch drives the warning light . Try disconnecting the wires first then and try grounding both to see how the light responds and how the gauge reads . Jim Bailey 928 International jim@928intl.com 79 928 5spd 80 928 5spd 68 911 5spd
