Hello,
My issue is that my livewell timer will only work on manual, not on Auto. It is a TH Marine Automatic Aerator Control Switch. I have it hooked up EXACTLY as the instructions show to a Johnson 500 gph aerator pump. Red (+) to (+) on battery, Black (-) to (-) on battery and pump (-) and brown wire to brown on pump. I have also checked the battery voltage at the switch, the buss panels and the batteries themselves, and I am getting 12.4v. I returned the 1st switch thinking it was a faulty timer, yet now the second switch is doing the same thing. The batteries are 2 12v wired in tandom (pos to pos, neg to neg) and I have even tried going through the original switch and through the buss panels. No matter what I do, the pump will not come on in auto but it runs fine on Manual each time. I've switched it to auto and sat next to it for 10 minutes while it was on the "minimum" setting. Just to be sure. I feel like I'm losing it with this one, there doesn't seem to be any reason it shouldn't work.
