TEMP. GAUGE NOT WORKING!

[DDAYMEN]

THE TEMPERATURE GAUGE ON MY '86 RELIANT WON'T WORK, NOT EVEN IF I GROUND OUT THE SENSOR WIRE!
ALSO, IS TH E SENSOR FOR THE TEMP. GAUGE THE ONE WIRE LEAD, WITH THE SENSOR LOCATED BETWEEN #1 AND #2 CYLINDER? I KNOW (THINK) THE ONE THAT IS LOCATED ON THE THERMOSTAT HOUSING IS FOR THE COMPUTER/ENGINE MANAGEMENT.
ALSO, THERE IS ANOTHER WIRE THAT LOOKS LIKE THE PREVIOUSLY MENTIONED ON FOR THE TEMP. GAUGE, BUT I CAN'T SEE ASNY PLACE FOR IT TO PLUG IN TO (WIRE IS BROWN). ANYBODY HAVE ANY SUGGESTIONS?????


THANKS, DDAYMEN
