I am not necessarily recommending these parts that I found online.
They might or might not be a suitable replacement.

Is your meter capable of measuring frequency? If not, try AC.
The vast majority of electrical problems are due to bad electrical connections.
Check for a loose or corroded connection or a broken wi ... |

While the main alternator is running, the 5AH standby battery should be

I agree with Charlie about using 2 separate switches.
Put dots on your schematic at wire junctions.
The diode is backwards. |
