Help me out please: Black probe to white wire, red probe to yellows give a tone and 0 out readings all 3. Reversed gives OL, no reading no tone. Meter set to voltage resistance now (the triangle with the wall symbol) Red probe to white wire, black probe to yellows: no readings 0.00. Black probe to white, red probe to yellows: identical .6 readings. Black probe to b/y wire (ground) and red probe to yellows: equal resistance reading of .6 Reversed: Same consistent readings of .4 There's a brown wire I ignored. Is my rectifier okay? Rewatched video, might need replacement since I got a reading both ways on the negative b/y cable.
Question: Tested the rectifier on my Honda Rebel 250. 2009. Found testing the rectifier that all measurement read O. L. So it's bad. My question is, would this keep the spark plugs from firing? This is the cause I been chasing down for about 2 weeks. Bike wants to turn over when I press the start button, all safety switches checked, and the engine pistons are moving. There's just no spark. Have tried pulling the plugs out and grounding them to check for spark. I've already replaced the spark plugs, checked resistance on my coils feeding the s. plugs and also tried staring up with a fully charged battery.
Hey dunno if you still read the comments on this but i have a problem with my recreg ( think) i keep blowing my main 30 A fuses i disconnected the recreg and it started up and ran fine (obviously no charging of the battery) then i plugged it back in (and checked voltage from the negative terminal of the battery and the outer casing of the recreg and it had the battery voltage i am assuming this is my issue the recreg shorting out the system and blowing the fuse? have you seen this issue before or have any tips of further troubleshooting? i tested the recreg and it was getting the appropriate values i think it is working fine other than the outer case shorting do i need to buy a new recreg or could it possibly be another issue?
When I had the positive lead of the multimeter probed into the 3 yellow wires, I got 0.45 ohm for each one of them. But when I had the negative lead of the multimeter probed into the 3 yellow wires, two of the yellow wires showed 0.1 ohm each and one yellow wire shows 0.09 ohm. Is the rectifier still ok or is it malfunctioning already? I had also checked the 3 wires with the multimeter's positive lead probing the rectifier's positive wire and then the multimeter's negative lead probing the rectifier's negative wire. I got OL for both tests.
Hi mate, good vid, extremely helpful. On the stator first vid no breaks test all fine and no continuity test all fine but how do I test for actually getting power through the 3 yellow wires to the regrec ? On the regrec itself and the 12 tests between the red/black to yellow, green to yellow, I'm not sure on the results. The results were consistent enough, when I swapped the polarity I got either resistance or no resistance but Compared to your tests mine were the other way round in terms of polarity. my red/black leads were plugged in correctly on my multi meter. Is that a faulty regrec or doesn't it matter ? Trying to diagnose a no spark. Cheers. Great upload BTW, thanks, Rich. P.s my bike is a 1981 Honda CX500 ( not the enduro, it's the CDI version )
With everything plugged in and the engine running, you should measure around 40 - 60 volts AC (similar readings) on all three input lines to the regulator
My bike is honda 750 custom. My regulator rectifier had damaged. Can i use another one. It will be from another bike. But it's 1100 cc?! My bike is 750 cc
Joe G I would be more concerned with very different readings between the diodes. You looking for a go-no-go situation. Readings one way and not the other.
Hi I need Your help. I have done test similar to Your. Here is effect: ua-cam.com/video/BRbzt7J3qJs/v-deo.html When I checked green wire connected to black cable in multimetr and red cable is checking yellow wires I saw one of 3 yellow pin have got signal which shows connection. Which is probably bad? What You think?
Can i use a different rectifire with same wire patter black and white and three yellows for differnt bike
Help me out please:

Red probe to white wire, black probe to yellows: no readings 0.00.
Black probe to white, red probe to yellows: identical .6 readings.
Black probe to b/y wire (ground) and red probe to yellows: equal resistance reading of .6

There's a brown wire I ignored.

sounds like a regulator does it work with a fully chargged battery? it shoud even with a bad reg

As easy as it gets. Thanks

+Hugg uai How old is the reg/rec on the bike? What’s it off of?
The difference between 0.1 ohm and 0.09 ohm is insignificant.
So I just checked mine, it’s reading consistent 1.0 ohms. But is 1.0 ohms okay?
Thanks. Very helpful!
Awesome video, thanks
You like back probing

thanks finally got it :)

Maybe. Depends on the control wiring.
Yes you can
"I like back-probing a little bit more", I bet you do :P
😂
mine was reading over 700 is that normal ?

Its "OPEN LINE" not 'out of limit'
