Problem
Electrical Gauge reading between 200F to 250 F. Engine at 180F
What I have done so far and still not fixed.
Replaced Thermostat
Replaced Sending unit 287.4ohms to -22.7ohms 12v
Replaced Gauge 287.4ohms to -22.7ohms 12v
Run new wire from sender to gauge.
Sanded all ground connection on frame and engine
When I attache the MultiMeter to signal wire and ground it shows the correct ohms.
I attach the Signal Wire to the gauge it will drop 100 ohms to like 20 to 60. thats like 200f - 250f
Losing it, probably switching to mechanical coolant temp gauge\
Thanks Timo
