Testing the Regulator / Rectifier with Multimeter

[londonboards]

This is a copy of a post I have in The Projects / Rebuilds section of my thread GS1100G Road Runner project.

So I'm following the Stator Papers testing procedure. I'm trying to determine if my charging problems are as a result of a faulty Regulator / Rectifier. I'm here:





I have the piece of kit off the bike and I am using a multimeter in the Diode Test position:



I get the same reading connecting the red multimeter lead to the red terminal and testing the three yellows.







Now the testing papers suggest that a positive result should produce a reading of 1.5v or better. What is a reading of 631? Is this reading .631 volts and and is the regulator / rectifier therefore below the 1v service spec? Is it functioning or not?

The first thing to do is not read those as trying to diagnose a bad R/R or bad stator sitting on the bench is difficult at best and the original stator pages do try and lead you down that path. If you have no other options it is OK, but a more thorough tests of a running bike will get you there faster.

There are updated Stator Pages see in my signature 'GS Charging Health and "Quick Test".

If it is not too far apart, just slap it back in and do the QT and report the results here.


You might also read GS Stator as well.

Thanks. I'm not an electrician. Can you tell me what 631 on the multimeter signifies?

Neither am I.

However, since you are on diode test, I would guess it is a forward voltage drop of a diode in mVolts. 0.6-0.7v is a standard forward voltage drop of a diode. But I have not read the manual for your meter so consider it an educated guess.

probably 631 ohms, not a voltage drop if you are measuring resistance

Yez absolutely if he was on the resistance scale

Forward voltage drop in mV.
