Dont have a power cable quite yet. Just for testing purposes, looking at the radio, top up, what is the polarity on the power connector?
Thanks

Re: 110w Astro Spectra Power Cable Polarity
I don't have one, but... here's a good tip that comes in handy if you don't know it. Take your multimeter, put it on the continuity setting, and put one probe of the multimeter on a bare part of the chassis or a shield (a known chassis ground), and then the other probe goes to the power connector. Find the one that has continuity... that one's your ground. The other one is... not your ground, or as humans would say, your positive input

The one on the "outside" with the flat profile on one side is the NEGATIVE pole, the round one on the "inside" is the POSITIVE pole.
curmudgeon.....and I like it.
