Need some help on this one.

My parents have a 2014 45' Allegro Bus, not sure of the exact model but, since August of 2021, the coach has sat, mostly because the parents are aging to a point neither feels they should be on the road in such a large coach. My Dad asked me to come over and look at the coach because he didn't have any power to the chassis or the house. Ifounf the 10ga. extension cord that was plugged into a 20a circuit had melted on the nuetral side of the plug, so no shorepower.
I have replaced the end on the extension cord, and now I have shorepower but, I have nothing on the inside.
Due to the duration without power, the chassis batteries were also dead, put those on a battery charger, waiting to see if they will take a charge.
I check both the house and the chassis disconnects and they are both on, still no line voltage inside. I would like any advice you have to offer - since it is much different than my Monaco, I'm a little lost. Thanks.

When you say you have no line voltage inside do you mean no 120v to any outlet or no 12v to lights, etc? If no 120v, check the transfer switch to see if it has line voltage out. FYI, if the house batteries are that depleted, the built in converter/charger will not take over until the voltage is above its minimum cutoff point and they may be toast. They will need to be on a heavy duty charger for a while before the coach charger takes over.

LT Dan - Thanks for the input. I do not have 12v inside and I didn't see the clock on the micro blinking so I assumed no 120v inside either, I will check the plugs to verify. Not sure when my Dad lost the shorepower, I can only assume it has been several months to have the house batteries fully depleted.
I will put the heavy duty charger on the bank of house batteries and see if they will take a charge.
Thanks again.

You don’t mention where this Bus is parked. Is there a chance the reason the melted neutral on the extension cord was caused by lightning? If so, the transfer switch might have take a surge, in which case it will most likely have to be replaced. Even the loss of a neutral can cause a surge.
