yep. I'm thinking on disconnecting meter and run it straight to batt, eliminate anything in between. That should give me the answer I think.
Measure the voltage at the gauge with a meter - that will tell you if you have a voltage drop somewhere. If the battery reads 14.2 running and the connector at the gauge reads 13, you had better get to checking connections and wires for looseness or corrosion.
You can adjust the meter needle to match the voltage measured AT THE GAUGE CONNECTOR through the tiny hole in the gauge with a small flat blade screwdriver. You will be able to adjust the gauge dead nuts to the voltage at the connector. DO NOT SET IT TO VOLTAGE AT THE BATTERY POSTS because the gauge is not directly connected to the battery.

Thank you. That helps tremendously.

Put your negative at the battery, and postive at plug for meter. I think will tell you if ground bad. Can try reading the other way too. postive at battery, and negative plug for meter.
