That On/Off CB Switch has 3 wires
RED and BLUE on one terminal and then RED on other terminal
RED/Blue....red is 12VDC + from DC Dist Panel (FUSED)
Blue sends 12VDC+ to the thermostat
RED on other side goes to Timed Delay Relay.
When Thermostat closes then 12VDC+ goes to coil side of Timed Delay Relay which allows the 12VDC+ on RED to go to Fan Motor
So you should have 12VDC + on RED/Blue at the On/Off Switch and on the RED from Switch to the Time Delay Relay (Green Box)
Yellow is NEG/Ground
I have 13V at the 2 red wires and the blue wire shown in the above picture. Not sure what to check next.
I forgot to mention that the AC nor the fan for the AC work either.
