I hooked up a water temp gauge.
Now when it's running, I get crazy, rapidly changing readings on two different multi-meters across the battery.
Engine off, 13.25 volts if it's just been running, 12.7-something after a few minutes. Normal, ...
I removed the alternator wire to rule out a bad voltage regulator. Same thing, ... crazy meter readings while running. Steady when not.
I removed the + wire from the water temp gauge. Same thing,...
All I can think of is I routed the sensor wire past the ignition wires and there's some kind of inductance going on??
Tomorrow I'll fire it up with the w.temp sensor wire disconnected at the gauge and see what happens.
Everything works though, including the water temp gauge.
