Unless you are a certified ASE mechanic, everyone starts this way. You don't have to work on your own truck, its just easier on the wallet most times if you do. Maybe get a cruiser guru to initially dial it in and then take it from there. These trucks are just not really the sort of 'get in and go' vehicles they used to be. Lots more to owning them than paying registration and filling with gas, but it all part of the Cruiser experience. As you work on one system, try and educate yourself as much as you can on how that system does what it does. As you touch more and more systems, you will understand more and more about the truck. The good news for you is that these are as dead simple as you can get. so you have a fighting chance at actually working on it, which is different from a modern vehicle that requires an IT degree to fix. One step at a time. Just remember everyone starts somewhere, you aren't born with mechanical experience, and no one knows everything (although a lot of mud members come real close). Even the experts on here started somewhere and most started when these trucks were brand new. The rest of us are playing 30+ years of catchup. Since owning mine I found myself doing things I never thought I would be capable of. I assure you, if I can figure this out, you can. GL. HTH.
