I am having issues with my garmin 73 sv. But I think it's the bail mount. I don't have a ohm meter. But I have a cheap little test light. The power cable has 1 female port hot. The other 3 nothing. When I remove my head unit, there is a 24 pin connector. I can't get that test light to light up on any of the female ports. I'm not sure which one of the 24 pins should have power. And I can't find a schematic on line.
If anyone has any info please help. I'm tempted to spend 30.00 on eBay on a replacement. But right now I'm not sure if it's the head unit or the bail mount.
