2 plugs one is a cigarette plug the other is aux plug. I keep a 100 w inverter plugged into the cig plug until it quit. Voltmeter says 0 fuse is good. So I plugged inverter into aux plug. It quit so I tested it and the aux plug shows 75 volts. That’s the problem how is there voltage so high? Ran an aftermarket plug direct from battery and it shows 13.9 average. I just can’t figure out how I’m getting 75 on my aux plug…! ![IMG_20191009_093944_01](https://global.discourse-cdn.com/cartalk/original/3X/8/8/881a06e1700645a7c24a16c1792852a28a0fa511.jpeg) ---

Maybe if you look again you’ll see a decimal point mixed in the ‘75’ reading somewhere. ---

Could be voltmeter is on wrong scale, or as mentioned overlooked decimal or ghost readings. ---

Doesn’t that screen indicate 74.6 milli volts? It does indicate it’s running on AUTO RANGING. ---

Right that says millivolts , so basically you are getting little to nothing out of that plug .
