^^^^ - that schematic is your best friend - print it out large format in colour and go for it.

As others have said - TAKE THE BIKE BATTERY OUT of the equation entirely and just use an ohmmeter to check whether connections and wires are in good condition.

You do not need an expensive meter - just a little $10 unit from Radio Schmuck or something like that will do the job just fine. The key thing is to work methodically and be organized.

It sounds as though it might have been running on just one cylinder - so check for an ignition system problem.

...and THAT my friend is the seldom boring, often obstreperous and always entertaining....Lucille .
