System works AFTER removing battery fuse

[Strider]

I have an old SES solar controller/monitor on my 2000 Chinook RV. Yesterday I had the genset running to charge the house batteries. This panel has a vertical row of colored lights to show battery charge (green lights, followed by yellow, followed by red) The top two green lights did not come on after running the genset for quite a while.

For some reason, I removed the battery circuit breaker from the controller/monitor panel. When I removed the fuse all of the green lights illuminated. Is this normal? Does this indicate that I have a bad battery? Any help understanding this would be appreciated.

you need to look at the system schematic to understand what is happening.

I absolutely agree with that, now how about telling me where that can be found because I've been searching for days for anybody's schematic.

Don't know the answer to your question. Speculation: the lights are a voltage meter... when the battery voltage gets high enough all the green lights come on.

Either your battery is shot and cannot be charged up to a high enough voltage, or the charger is defective.

When you remove the battery circuit breaker you remove the load from the charger and its voltage shoots back up to normal.
