How to check the D14 diode on my D1 control board

If you have a solar unit, the battery power will travel throught the D14 Diode (top left corner of control board) and feeds power to the main control board. To check if the diode has failed, create a bridge (as shown in the image below) from one side of the diode to the other. Making sure that you have a good connection, try activating the gate with either a remote or visitor accessory. Does the gate operate?

If yes, great! Secure that piece of cable in place and run the unit as is for a few weeks. If everything is still operational after this time, then you can go ahead and replace the diode with either a 6amp or 10amp.

If no, then you can either call the office for further assistance or try further troubleshooting here.
