New to the Maxum world

Does anyone have the owners manual or at least the wiring diagram for the fuse panel.

Electrical issues:

No trim tabs
No fridge
No range
No fresh water pump
No shower pump
Battery charger only reads 6-8 amps

Has two shore power hookups one for ac and the other is for everything else. Changed inline fuses where I found them. Everything else works fine! When I bought the boat I was give a 2-1 “y” so I only have to run one shore line, can I do this and still run everything. It’s a 30 amp shore line. Also the green lights on my breaker panel flicker and don’t stay solid.



Does the breaker box go through the fuse panel or is the fuse panel only for the dash electronics?

Welcome aboard

The breaker panel is only shore shore power 120VAC. The fuse panel is for 12VDC.

Trim tabs are an option and wired separately. What brand do you have?

Frig should be dual volt and run on either shore power or 12 V. If the switch inside on?

Range is only shore power or a genny.

The pumps are 12V only.

You will need to break out a volt meter to see if power is getting to them or not.

I don’t know the brand of trim tabs,

I turn the switch on inside of the fridge and don’t get anything. Would there be an inline fuse?

The switches for the water and shower don’t illuminate when I flip them so I would think I’m not getting power to the switches.

I replaced two inline fuses that were just off the house battery one was a brown wired the other was an orange wire with a red twist.
In regards to the water pumps, are there any valves that I need to turn since the are on demand? And any more inline fuses I should be aware of?

What color is the trim tab pump housing?

You may need to pull the frig to see if there is a fuse. At this time you can verify it’s getting 12V and 120VAC when on shore power. If either are there but the unit doesn’t run the frig power supply is most likely bad. Boats typically have cheap fuse block that go bad from corrosion, you need to verify voltage at each fuse.

Sounds like Bennett, they have a great service group that can send you the wiring diagram if you contact them.
