Got one of these that holds all three car calls. Car will just go to the floors up and down. It works correctly on phase two fire service. We drained cap for a couple of minutes. We were going to try draining it longer next time. Any other ideas?

We tried again today by draining the cap longer.To no avail. There are no car inputs or outputs on, but yet it just goes to floors and the car call lights are lit up.(with no call light output led on the CPU board and no car call input)

Bad CPU board or bad ram chip. Any ripple on the power supply in COP?
