No power to main switch

Hi All,
We had a little mishap with our 2018 Vegas 24.1 and can't seem to figure out how to fix it. While installing the coach batteries, one of the wires fell through the step and touched metal. Since then, we cannot get power to the main switch, monitoring panel, or lights. It does not work with the batteries or when connected to shore power or with the generator running.
We have replaced the main switch (the tab on the back broke off when we were using a voltmeter to test it) and also replaced the battery disconnect relay. Two 40 amp fuses were blown (believe the reverse polarity fuses) and were replaced. The 100 amp breaker near the batteries was tripped, but not the 50 amp. We have checked the breakers and fuses in the main box as well as the one in the engine compartment.

Any other ideas?

Define "It"

Trip and reset the 50 amp breaker
Verify your battery connections are now correct.
Check your converter AC breaker.
Check your house battery voltage
Check the 5 amp fuse(s) on the latching relay (for the USE/STORE switch)

It = power to main switch, monitoring panel, and lights

How do you manually reset the 50 amp breaker? There is no button like on the 100amp breaker that we have found.

Go to the AC circuit breaker box and reset the Converter breaker. turn it off then on. Don't just LOOK at it. Looks like you checked everything else.

I believe he is referring to the 50 amp main AC breaker.

There is no 50 Amp AC breaker in a Vegas.

Well since I have not been within 50 feet of a Vegas I would not know that. Now I do.

He did find the 100 amp battery fuse so I just had to assume we were talking about a 50 amp breaker since many people don't know the difference from a fuse and a breaker.

Don't have a clue what the 50 amp what ever it was is for.

There is 50 amp, 12 volt circuit breaker between the house battery bank and the latching relay near the power center. The circuit breaker is an auto reset and not a manual reset.

Yes, the 50amp, 12 volt circuit breaker - thank you. I was driving myself crazy trying to figure out how to trip/reset it.

There is no sound from the latching relay when the main switch is pressed, but the two 5amp fuses are good. We thought that indicated a bad latching relay and replaced it. No change.

We've compared the battery setup to the schematic and it looks correct. The emergency start works and the generator will start which leads me to believe the batteries are hooked up correctly. The batteries are showing the correct voltage.

We reset the AC breaker in the main box. We've checked all the fuses and replaced the two that tested bad. We even reset the GFIs, just in case...

Still no power to the main switch. I feel like it is something so simple we are overlooking.

Turn off the converter. Use a volt meter. Start at the battery. Check for voltage there. Check for voltage at the disconnect solenoid. Both sides on and off. Follow the wire to the converter, or to the inverter/charger, which ever you have. You need need voltage in and out. Just like reading a read map and crossing bridges. Switches and relays are the bridges.

My battery disconnect switch is the momentary Use/Store/Center off type by the entry door. Power comes to the switch through one of the 5 amp slow blow fuses on the latching relay (the house battery side of the relay). Two other wires go in the same wiring harness to activate the relay. So, the switch hot anytime there is 10.5 volts in the house batteries.

The generator is not connected to the batteries via the USE/STORE switch.

What's the voltage to ground on both sides of the 50 Amp DC breaker.

You really can't do any more troubleshooting without investing $15 in a multimeter and 30 minutes on Youtube university to learn how to use it.

This doesnít address what the problem is but always disconnect the ground cable first and connect the ground last. By ground I mean the last ground cable that connects to the coach ground/frame. This way no sparks if you accidentally touch a hot wire to ground.

Some inverters have a fuse on the inverter itself check that. it is physically on the inverter..

Inverters do not charge batteries.
There is no inverter on a Vegas/Axis 24.1 from the factory.

I am sorry and don't want to get into an argument but Inverters do charge batteries, I have one on my 2019 30FE, and if you have batteries and connect to ac power you either have an inverter/converter there is a fuse on it protecting it.

But, it is common for an inverter to have the charging capability. i.e. the popular Magnum brand.

That would be an Inverter/Charger. A different class of device than simple Inverters,. Simple Inverters do one thing: they invert a DC voltage (normally 12 VDC) to AC voltage (normally 120 VAC).
