Rick,
I think the way I described it is correct. I have read about folks on this forum who have wired it reverse...just as you had done but, the gauge didn't fizzle out.
Granted, you are installing a new 12 volt gauge, but it would be interesting to test the old suspect gauge with 6 volts and see if it indeed died from the reverse connection.
If I had to take sides on this issue, I think I would go with the assembly manual, no offense to Randy...or his typist!
