Hello, I am troubleshooting a driveway gate operating system. It runs on 24 volts (2 12-volt batteries in series). It runs on a transformer that converts 110 VAC to 24 VAC. Then the control board converts the 24 VAC to 24 VDC to keep the batteries charged. My problem is that the batteries are not getting charged. I discovered that the control board power going to the batteries is only 20 VDC, and it should be at least 25 VDC or so to charge the batteries.
Could someone possibly be able to describe what to look for on the board that might be the problem?
