The most common cause of this problem is batteries that need attention. They may have dirty terminals OR need a good charge or replacement if they are over 3 years old. Load testing would tell you that. Most places the sell them can do this for you. IF you do take them out, be sure to FIRST take a photo of the cables and make a diagram of the hookups or it is easy to get this wrong. You may want to check the charging and be sure this is up to specs as well. A small digital multimeter can assist you there and those are about $20 or so and easy to use. I can direct you in that. Start there and then get back to me if you are still having an issue and we can do some testing. All follow ups are included in our fee. Please included the name and number off your control pad when you respond so I know what you have here.
