Newmar PT24-45F Charger Issue 230v

Were here in the Abacos and the above battery charger has quit working. It supports the house and engines. 3 banks of 6 batteries. 2 banks house and 1 bank engines. Never had the charger fail before. Read manual and it says there are some internal fuses but recommends only for a manufacturer tech. Not sure these would even fix the problem. Since this charger maintains many of the devices used on this boat I am currently and literally at a standstill. Since its Saturday there will not be anyone at the factory.

Good news is I'm at a marina and not on the hook. Bad news is the charger. Battery bank for engines is okay although haven't tried to start them. Did check voltage on those two batteries and they were okay.
Guess I could start engines and jump power to other batteries although that would only work short term. Trying to disconnect charger to look inside to see if any breakers, fuses, etc that might be tripped. Other than that guess I'm pretty much screwed. No place is open on Saturdays that could ship or even call for support.
It appears not many companies sell this charger based on my internet search.

Going to try and remove although not easy like most things on a boat. It is definitely getting 230v power to the unit. From there not sure.

In trying to remove the charger in the engine room, behind the main cutoff switches for engines, gen and house I found a Xantrex Pathmaker 250/2 24v item. It has a green, yellow and red light on it. The light is in the yellow mode and when I try to reset it will go to green until I release the switch and it goes back to yellow. Not sure what this device is connected to or whether it has anything to do with the Newmar battery charger? Anyone shed any light on this product and what it does?

Another question the battery overheat cable that runs from the battery charger to the battery box was wired at the factory so the plug will not go through the hole in the side of the battery panel so will have to cut and try to run new cable to battery box which might be an issue getting it there. Temporary no problem will just lay in battery compartment but won't be run through any chase like the other one.

Okay what does a battery combiner do? Does it have any impact on the battery charger? I started the engines and gen and noticed that there were now two lights on the combiner. Red was flashing and yellow stead.

Yes that is it. Pathmaker 250

Yes that is it. Pathmaker 250 with red light flashing and yellow light steady. I did read it but still confused. Could this be because the charger is unwired from ac power.

No remote control that I am aware of. In my 5 yrs of owning this boat it is the first time I've seen the combiner.
I have unwired the charger to replace one that I just ordered. Will have end of week if boat makes it over.

Can you post a diagram with 3 banks. I am not able to find all the info you have posted.

Will definitely do. I hated to cut the cable running from the charger to the batteries to sense overheat conditions but was not able to remove charger without cutting.
