Multimeter testing of charging system

I have a Craftsman digital multimeter and would like to know, what setting is for diode testing. The book for the tester is long gone. This will help me with the testing of the R/R before I get a stick of explosives to put in the tailpipes.

Thanks
 
Thanks Rusty,

The multimeter has a center dial for each testing position. There is no diode or x1 position. Vdc, Vac, Aac, Adc, BAT, and OHMS are all it shows with settings of voltage or resistance in each.
 
Ohms setting it is then, but a digital vom it may not have enough current flow to turn the diode on. search the web for the manual they are available online, i found it for one that I had and gave away. :)

Did you look to see if you can download a new manual? I've heard from a very reliable source that the ohm function will tell you if a diode is bad but can't tell you if its really good. The diode handle upwards of 80 volts AC and the ohm tested throws 3 volts +/- DC at it. If you're stator checks out OK for continuity, not grounding and output and you connections and battery are OK then it is the R/R. Got a Honda CM R/R on E-Bay for $1500. You gonna light the explosives?
 
I decided to just buy a new R/R and be done with it due to two of the wires were fried. Went to Electrix for a new one and was ****ed at my local Suzuki dealer when i found out that i could get both the stator and R/R for what i paid for the stator alone. It was before I found this wonderful site. Will not make that mistake again!!!!!

This eliminates the original question of the diode test. My meter goes from 20000k to 20 with the final position being audible. Thanks for the info and I will go to the craftsman site to find the manual.

Thanks for the help.
 
Ohm, or continuity if you have one of those. Basically the voltage in one direction will cause inifnite resistance (ohms) and voltage applied in another direction will cause a low resistance, if you measure in the Kohm range you will probably get < 0.1 KOhm for a good reading.
