Why is 1 side of the amp gauge connected to ground?

because Texans love their barbeque, and they never do anything small.

I was thinking there was a voltage gauge put in.

I will update, but I did a volt gauge conversion too.

lol especially the Texas Twinkies! I responded the AMP gauge was converted to a voltmeter.

Here is the voltmeter conversion. I this this because there is a 180amp alternator on the car, and I didn't want to run a shunt to keep the voltmeter.
