I put this together in a hurry so please remember to repeat the test as instructed toward the end of the video in order to ensure the checks are complete.
People should know that you only tested 6 of the 11 diodes There is 5 more diodes that need to be tested It is better to test the diodes thru the terminals first and if you find a problem then flip over to the circuit board and look for bad solder joints Also there is a "diode setting" on the multi-meter for testing diodes The faulty Diode is one of the main negative diodes and you do not have to remove them to find out which diode is bad
mrclubik, Thanks for the comment. Yes, as stated in the video there are 11 diodes in all, but as the title suggests this is just a quick test to establish the serviceability of the main phase diodes, since in my experience these are the ones that usually give trouble. The other diodes can be tested and replaced, but I doubt that many folks watching would go to the trouble of dismantling the rectifier to access the circuit board in order to carry out a repair. However I have come across rectifiers that have had one of the diodes I was testing soldered into the circuit on the outside. As for the diode test facility, yes I could have used it, but not all multimeters out there will have this.
Sorry my explanation could have been better in this video. If you look at the leads where they enter the meter, you will see that for each test I have swapped sockets, i.e. right to left/left to right. This effectively reverses the current path from the meter each time, hence it allows me to determine if the the diode allows current to flow in one direction only (as it should), or in both directions (undesirable). Hope that helps.
Very useful, no nonsense, straight to the point.
I'm confident my diode board is good enough. Now to test the regulator...
Cheers mate 👍
Great video and info as usual!!
great video, i have a problem with my charging system, i gonna check the diode board tomorrow
Ran this test on a heavy duty diode board today and found out why there's no charge. Cheers, H

ANY Idea the Bosch part number for the diodes?
if i use a combined reg/rec does that mean i can get rid of the diode board? i have a R80
TheJDenz I don’t see why not, you only need one rectifier.

So do you gator clip the negative terminal or does it matter? .....you don’t show it or say. Both your leads are red

@@motophoenix5951 thanks. Yes that helps
great info but sound a bit low
Sorry about the sound, camera is a bit basic.
