I just replaced the house batteries on my 2016 Jayco Precept 31 UL and i am getting no 12 volt power. the battery disconnect switch does not turn on at all. does anyone have a picture of how the two batteries are wired i thought i connected everything the way it was ?

Welcome to the forum!
Sounds like you possibly wired it incorrectly. There are two fuses in the electrical for reverse polarity. Usually 40 or 50 amp near others but separate. Then you have a solenoid with two large studs for battery cables and two small ones. Check the inline fuses there.
But you must have your batteries wired correctly first. Find the cable that goes to the metal frame. Connect it to one battery, negative. Then take the (usually) 2 or 3 other cables to the same battery positive. Do not connect other battery yet. Then replace any blown fuses, and see it it works. If it does, add one cable from pos to pos and one cable from neg to neg between the two batteries.
Best wishes!
