I put more faith in a simple bulb tester, than I do an ohmmeter or voltmeter.
corrosion will conduct enough for meters to "show good", when in fact, it is a bad high resistance connection that fails under heavy loads.
I like to use a voltmeter ACROSS the junctions in a circuit to see IF there is any voltage drop across that junction. if there is, it is bad.
e.g., for the starter motor.... measuring the voltage drop from the battery + terminal to the starter's 12V post will give the total voltage drop across the entire circuit, including all of the relays... that is a fast go, no go, way to test starter problems.
