The wrong wire may be hooked to the sender or there is a short in the wire going from the sender to the gauge. Do you have the right sending unit. There is a difference in the sender for a light or gauge. When the wire is off the sender the gauge should read O. When it is grounded it should read hot. The light green wire goes to the temp. & the blue wire to the oil.


They say money can't buy happiness. It can buy old Chevy trucks though. Same thing.
