Hello, can someone told me how to test my rectifier out of ski with a multimeter? I read a lot a look for video and not sure the correct way for that particular RR. I order a new one because my battery dosen’t charge will running, I read 12.5v running or not even rev over 5k. I perform diode test from red to each yellow and got nothing reading except for the female yellow one, on both is the same reding issue, new and old one. Inverse the probe multimeter, same result. I know that some new rectifier can be bad but I wath to be sure before returning it. Thanks for your help.

Yeah I know that. Thanks
I install the new one this afternoon, no voltage build up at battery. So the new and old one are bad or its my stator. I’m Not sure that I what to investigate on that... That’s why I would like to try the rectifier alone. Mean while my gtx run perfectly until my battery comes out. So fews hours 5-6h... and the battery out.
I know you will be the first to help me on that mikidymac... thanks budy are you surrounding Montréal for fun?

The rectifier is converting A/C to D/C via the stator, so you'd need the A/C stator output to verify the rectifier. You could ohm test the stator, look in the service manual for the procedure. I'd conclude the stator is kaput if both the old and new rectifier provide no change in voltage while running.

Another thing to check...just to rule it out.....look at the 15A fuse in the rear electrical box.
Yesterday my sons riding lawnmower was giving him trouble, battery was drained. A real quick check: got the engine jump started, checked battery voltage with engine running, battery was less than 12v and DROPPING while running. Located his inline fuse and it was melted into the fuse holder.....a quick replacement and we were back in business. It was fast for me to figure out the problem BECAUSE of all the work I've done on my '96 GTX chasing 12V low problems.

can someone tell me if my stator do something else execpt charging the battery on my 96 GTX?
My stator past out, I will remove it and install a new one in fews days.
Except of that I need to charge my battery by myslef once a week, my gtx run very well... Is that normal..??

Your stator produces AC voltage which is converted to DC voltage by your Rectifier/Regulator. The DC voltage then "trickle" charges the battery and provides DC power to your ignition coil to fire your spark plugs.
A properly functioning RR will show a steady VDC voltage of 13V+ at the battery terminals with the engine running....if the voltage is bouncing all over the place, the RR is not functioning properly.
You can OHM check the stator pins to see if the stator itself has , at least, the proper wiring paths (no breaks in continuity).
If the "electrical" system (Stator/RR) is not functioning properly, the running engine will then just suck battery voltage to fire the plugs until the battery is exhausted. You should NOT have to charge your battery once a week.....your electric system is not functioning properly.
Where would one find these pins for purchase? I would like to have an assortment. I have had to cut a good harness to get the plug that I need.
Thanks so much. I sent you a message but you got me hooked up !! very much appreciated !!
