Even the small shops don't want to do electrical snipe hunts as they are way too time consuming if you don't have "good parts" to put on one after another to do your evaluations.
Electrical is the one area a person can use the forum papers to follow and learn the basically simple wiring on these old bikes. The most complicated tool is a good VOM and you're in business. With any luck you can pick up good used expensive components off ebay or this list for spares and trouble shooting duty.
These bikes are made to get wet and sit outside in monsoons so the biggest problem is PO mods causing shorts and bypassing fuseblocks, etc.
In short welcome to the club. I was lucky to find a person off this list who actually knows (and is willing) how to fix this old bikes. What a break!!
I did find a local Triumph dealer who will do some things like valve adjustments and carb syncing which is a good thing to have available
So don't "giveup" on all sources just the actual Dealers! As mentioned many times on this blog.
Get a good digital VOM and learn to use it in a day.
Yes bikes are rather labor intensive on maintenance compared to cars but they are generally more fun to "drive".
