Main and Aux battery switch explanation
Next on to the Main disconnect switch. It did NOT have 12v+ so I used a AC to 12v power supply with battery clips on the end to power the Main switch and it worked! I then removed a normal automotive 12v relay and wire brushed the leads and when going to reinstall the wires on it the tiny 24? gauge wire fell out of the crimp and when I felt the ...
batteries
Suppose the main power source is 12 V and the battery 9 V. Then the 12 V source will drop, say, 0.5 V (Schottky diode), so the voltage at the cathode will be 11.5 V, which is higher than the battery''s 9 V, so that diode won''t conduct …
