I recently purchased a 2023 Ranger Tug R27 which had been stored indoors for the winter. I've got the boat at my house hooked up to shore power with an 120v adapter and I the house power will not work unless I put it into parallel. I'm assuming the house batteries went to sleep but I can't seem to wake them up. I've hooked a jump pack to the negative of one of the house batteries and the main cable coming off the positive to the bus as I can't get at the batteries and they appear to be jammed under the deck and will not pull out. I've checked for continuity at the bus fuse and it was good.
Any help would be appreciated as I currently have no house power. Thanks
