I am replacing a series 6300 with a 7300 from pps.. Understand the install but must question the battery terminal connections. I thought negative was always the black wire. On the converter installed presently the black wire is connected to the terminal that is identifed according to the diagram as positive ? The new converter has the same connections but I question the wires being wrong. Is the black wire always negative?

Not in RVs. Odds are it is positive. The other wire quite often white is negative.
I would verify that the black is connected to the fuses in the DC panel and that it is connected to the positive on the battery.

The way I can get it in my mind is that AC wiring uses the Black wire for the hot. In RV's they often use Black for the Hot 12 volts except in the battery compartment. Don't leave home without a voltmeter.

+1.
Many folks don't realize any cheap meter will measure negative voltage if you connect that way. Easy to check.

A multimeter is a wonderful tool to have.

Usually, if the wires are black and white, the black wire is positive. If the wires are red and black the black is negative. However, there are no guaranties. As others have said, get a multimeter. I bought one on eBay for under $5 the other day.

2x on the digital multimeter. Measure and test, Then connect, that is the only way to be 100% sure.

Good thing you asked. White is normally ground/negative in an RV. Any other color in the 12v system is most likely hot/positive.

I'd just be happy if the 12v dc color codes remained the same between RV's and Boats.
But it is what it is, and you have to pay attention and use a meter.
