That is correct

That wire is the ground for the ACR. It needs to be connected to ground for the system to function properly

1. Remove the charge wire (red) for battery 1 from the ACR.
2. See a lot of corrosion on the positive (red) battery post. Clean both (red and black) battery terminals until they are shiny.
3. Put switch on battery 1 and measure the voltage with the engine off.
4. Then measure the voltage on battery 1 with the engine running.
If your voltage reading less that 13.6 volts your alternator is bad

Depends on how your switch is setup.
Typically battery 1 is connected to the motor for start and charging purposes. Battery 2 is typically wired to the power the "house" loads.

If you took the battery lead (big red wire) from battery 1 and put it on battery 2 and nothing worked, battery 2 is dead.

As I noted earlier, a dead or dying battery came do all kinds of strange things to a charging system

hi
na i did not put the big red on batt 2. that batter is good its 12,7 volts. battery 2 might be connected to other things maybe USB or something. but anyway 13 volts = bad alternator?

Not necessarily.
Depends on the charging system
What motor are we talking about.

Yes.....bad for an automotive alternator.
Maybe......for a stator drive outboard

Electronics don't die of old age, they die from abuse.

Something as simple as turning the battery switch off with the motor running or hooking the battery cable up backwards can blow an alternator
