Hi,
Please give me your opinion on this problem.

When I select the number 1 on the main switch (#2), all the devices get energy and the motor started
When I select the C on the main switch (both post), all the devices get energy and the motor started
But, when I select the number 2, where the post is connected to the reserve battery for starting the motor in emergency, nothing happens.
What is wrong in my wiring design ? Why the selection of the 2 selector, the starte don't received energy?
Regards
Robert C.

My first thought would be that Battery #2 is dead. Next would be to check for a bad connection somewhere.

Fuse ?

Can't you test with a VOM?

No, the battery is not dead. This reserve battery show full charge after two days unconnected and test with VOM.

check the sw2 to make sure you used the correct terminal for the common. use the volt meter to see how far the power goes to get to the sw2 and beyond.
