Resistor- diode assembly

[grywitt]

I looked back through titles trying to see if this has been addressed. The TM 9-6115-642-24
2-34.2 it says to test the resistors disconnect the battery cable then start testing each resistor. When I had checked them before I assumed they were in parallel with something and that's why they were 1 ohm. Then I read this and thought hmmm. Maybe they are bad. Then I checked my other gens. They all read 1 ohm on 10,11 and 12.

I do have a couple diodes that need to be replaced unfortunately but that's not what this is about. Am I missing a step? Is the TM just wrong? I usually assume you need to isolate resistors and other things unless you know what the reading should be. That or I need to replace a lot of resistors. Has this been discussed and I just didn't find it?

If you test with the resistor connected on both ends you your meter will find the resistance of the lowest Ohm path between your leads, which may not be through the resistor you're trying to test.
To get a true reading of the resistor, it's best to disconnect 1 end to isolate it.
Of course it's also good to double check that your meter is set correctly as well, to avoid erroneous readings.

That's what I was thinking the first time I checked them. Then I read the TM and started doubting myself. If you follow the TM you will change these pretty much if you check them. It doesn't say anything about isolating them from the circuit before testing. Oh well just curious.
Thanks for the reply
