Diagnosing high voltage

Then what Del wrote in post #32 above should make sense.
If not, ask questions.
The answers are all there.
Its now mostly a matter of how you learn best.
I'll say this, and this goes back Before Internet.
For a long time I looked for procedural answers. Step 1 do this. Step 2, do that. Some of the later service manuals have these. AMC called them DARS charts. These are not nearly as helpful as they seem. Troubleshooting requires understanding what the parts do and how they work together. Then the procedures suggested will makes sense, and even if they don't apply can sometimes be useful as an example of how to approach the problem.

For me, understanding what the parts do and how they work together required both the explanation and holding the parts in my hand. Everyone learns differently. I could do the math for a differential in school but really didn't understand in the same way until I saw one - and I don't mean just a picture. That's just me. So you have the parts in hand, I'm hoping when you read what they do and how they work together it will start to click.
