Recently getting the 1988 Itasca ready for a weekend trip, the charging system failed. It worked one day and quit the next. I can't recollect the sequence of events that led up to the failure. It may have failed AFTER I hooked up the house battery, But the condition remained after unhooking the house battery. What happened was the alternator dash light is on. I was getting no voltage from the alternator battery terminal. Changed alternator. Still no voltage there. I understand that a 1988 should be internally regulated. I also understand that there needs to be voltage INPUT to the alternator to make it work. There is a 4 wire plug in and I am getting voltage there but only about 7 volts. Is that right? Should I assume the new alternator is bad? I did not have the old one bench tested nor the replacement (which is re-manufactured). Coincidentally the fuse for the other dash circuit indicators/directionals was blown. I replaced that but still no charging. Any thoughts for this Monday morning headache? (By the way, my weekend trip was cancelled and I drank all the beer at home...) 🤪
Everything works fine on shore power. And I have not tried to rehook up the house battery to check my connections. Has been raining out until now...
P.S. I have been looking through the forum for clues but thought i would throw this out there. My main head scratching is the input voltage which I never knew about before...
Thanks.
