Too Low resistance on r/r

i tested my r/r and i get too low of a resistance for DC+ and DC-, is there any other way to test it? and what does this mean?
 
bike doesn't run, im getting 5 ohms negative on a and positive on e
 
i didnt test it both ways and i can't right because i used my physics prof analog meter , my digital multimeter doesn't read jack shit

OK, if you have only 5 Ohms BOTH ways, (don't know what you call it in English) meaning shifting the + and - multimeter connecters then testing.

I am afraid that you have to change the r/r.........

Look at the circuit how the sex-diods are wired and how the thyristors are connected, and you call follow what happends if you have a short in either one of the diods or the thyristors.

where can i find a diagram of the r/r?

I only have one (not fully complete) for GS 1150.

Ask here if the GS 1150 is the same as the GS550 or if somebody else has a diagram.
 
the resistance one way, negative on negative and positive on positive is 4.5 ohms and the other way i get no reading.
 
You should only get that reading one way. That's why Suzuki is specific about which way the probes are to be connected. I suppose it's because diodes only allow current to flow in one direction.
 
I am not real certain, I'm not a electrical engineer. But, it would probably lead to too great of a charging rate to the battery and maybe put an excessive drain on the stator.

A GUESS WOULD BE THAT WINDINGS HAVE SHORTED
 
ice109 said:
ok so what about the too low resistance?
Click to expand...

One way should be low resistance, the other way very high resistance (endless), if not,

you probably have a short, meaning the diode leads current both ways=useless as diode, in one or more diodes, mounted inside the r/r.

I used too drive rally car in former days and on a car r/r it was possible too both measure and change the diodes one by one, but I don't think that is possible on the GS r/r.

If you have a short in the bikes DC circuit, diodes can be overloaded and get shorted, age can also destroy them sometimes, but that is rare.

If you have a short in a diode, you should also check your stator and if the bikes DC circuit has a short.
 
u told me before i should be getting 50-70 ohms though and im getting only 5, is that ok?

I have only the spec. for the GS1150, and that is 50-200 Ohms for the DC-output, however I would not worry too much if a single Ohm value were not exactly as spec., there are a lot of things that can influence your measurement.

The question then measure diodes by resistance is if, too see that you have connection one-way and no connection the other way.

As I understood from your previous posts you have 5 Ohms one-way and no connection the other way, so I would carry on in my fault finding and leave the r/r for now.

If you are troubleshooting electrics/electronics you can get an idea if a part is broken by the resistance method, if you get values near spec. you should go on and measure with the parts mounted.

You must see the electrics as a thread and start in one end too measure you through the chain.

The Electrexs homepage has a very good description.

I scanned some GS 1150 pics. for you:

A shorted diode shouldnt cause an erronious reading in most cases. I am referring to the windings

I agree, as I wrote I would leave the r/r for now and start from start, meaning the windings.

The pics are just too still ice109:s hunger for r/r information.
