Hi all, I have a 2016 vista 26 he. Recently I have no 12 volt except when plugged in to shore power. The 2 40 amp fuses in the wf 8900 converter are good. My question is are there any other fuse(s) that should be checked, perhaps between battery and converter?
Since you have no 12v power, assuming the batteries are ok, I would check the main cables (positive and negative) from the battery bank. I had a lose wire and had low power because of it. Hoping to hear the solution soon. Good luck!

Also, hopefully someone who knows electrical will weigh in, but I've also heard the solenoid on these can go bad. On the 26HE it located in the LP compartment behind the bank of breakers, so it's not easy to get to.
