I was wondering how can I get a schematic diagram of a power source pc 40 battery charger/power supply for my 93 Fleetwood 30ft travel trailer I'm trying to fix mine before I buy a new one, I have Esperance from school and don't have the funds to buy a new one or a new trailer , I'm disabled, do what I can and like to do it my self, any help would be awesome, I'd like to try to fix it. I took electronics in high school I have the tools to fix it, the trailer has only been used for about 4 years and set under cover the rest, moved it recently and now no power but the 120 power , hope u get where I'm going, just tying to save money and see if I can fix it ,any help will be gladly accepted thank you, hope this is not too much too ask thanks murl (squirl)
