when switch is activated on each door nothing happens except for a humming noise coming from each soleniod in each door, took 1 of the connectors off from it and read dc volts in using the switch which got 12 vdc as i suppose it should for lock or unlocking, so I know its getting power, can only think its the soleniods, both, oh relay is clicking also when switch is used, would think that would be good also, anyway to check the soleniod, and where to get another, thanks rich
