Hey Ron,

What's the model or serial number? If it's Evolution or Nexus, see below.

I'd try a control panel power cycle first. Disconnect the negative battery cable and then underneath the control panel, disconnect the 2 wire white harness wire. It will have 2 wires inside, normally a white and a blue. This is the T1 power for the charger and when removed, should shut the panel down. Wait 30 seconds and then reconnect the battery and then the T1 once the panel boots up.
