hi im trying to test my regulator / rectifier on my 2003 501 .. anyone able to help me with values and for which pins.
thanks
 
Hi
There are ways to test them, but not so simple, so let's do the practical way.
When your engine is running you should get around 14 VDC to the battery, if you don't get DC your rectifier is bad, if you get much more then 14 your regulator is bad.
Simple :)

my engine well bike is under a full rebuild so need to test it off the bike
 
Hi

I didn't remember well the circuit of the 02, so I went to check it.

So on the 02 you have 2 circuits (2 yellows), one that goes to lights with just a regulator (so lights are using AC) and the other that goes to battery that uses one regulator/rectifier.

The regulator you can think of it like a switch, when it goes over a predetermined value it opens the circuit, then it closes again, to maintain a determined voltage. I don't know how to test it except if you supply it with some voltage and see how it behaves.

With a rectifier (that probably is a full bridge) you could test the diodes individually between the 4 poles, but in a regulator/rectifier not sure if it's the same (probably is) but I'm not sure witch poles are what, in this case.

Probably you could try to use the 220 VAC from your home connecting it where the stator comes in (stator gives much more than 220) and check what it comes out of the circuit.

:cool:

id prefer to find the values on the 4 poles in the regulator/rectifier just need to know what the values are, .. thanks tho zaga :D
 
Hi

So let me try, there is no value to measure in a rectifier. But it would be possible to check, let me try to explain.

Here you have a scheme of a regulator rectifier. It's not really correct for your bike because it's a 3 phase stator and you have a single phase one, but with 2 phases, but that's not really that important, my point is that a reg/rect is both things inside one box.

You also have a scheme of a full wave rectifier (it's easier to understand), as you can see this one is made of 4 diodes connected in a particular way. You can see one diode like a one way valve, it let's current go in one way but not the other. That is what is cutting the negative part of the AC wave and just letting the positive part go, trying to make a DC current.

So in a reg/rect the regulator part that is a on/off switch should be ON, because you haven't reached the predetermined value for it to switch OFF, so it shouldn't make any difference, so you could test the rectifier part. For that you would had to identify the poles, witch is witch (AC ones and DC + and -), then you could test the diodes individually.
As I've told you the diodes only conduct in one way, so most multimeters have one specific function for that, they induce a small current in one way and check if it's passing thru.

Not a very good explanation, but hope you understood.
