 As I posted earlier my starter repair guy says "start by measuring voltage at the starter and work your way back to the battery" assuming you know the battery is good. This is done while cranking engine!

I frequently hear stories from people who have thrown money away by guessing at possible solutions to problems by replacing good parts. Please provide anymore links to diagnostic techniques  you find relevant.

[Todd Markle Spring Mills, Pa.]  <snip> What you are doing with the voltmeter is called a "voltage drop test" and is probably the preferred method of diagnosing a lot of electrical problems in the modern automotive world. It is simple and very effective. 

If anyone would like to learn more here is some further reading;
