    Not charging - Kubota B7000

    The ones I found in amazon and aliexpress says its rectifier and regulator of 12v, so that should be the best option, do you agree? Then I also need to re-do wiring from positive output from rectifier to main switch and all should be ok to deliver 13.5 volts constant to Battery, I hope. Thanks...

    Not charging - Kubota B7000

    "The ones for sale online are $20 item, so can't be complicated( more parts inside )." You mean the ones for sale online have more parts inside and regulates voltage? I firstly understood you say they don't regulate, just rectifier.

    I'm getting confused :) sorry. Understood from you that the online rectifiers saying also regulators are not regulating at all, isn't it? If you tell me, those also regulate and are not only a bridge diode rectifier, i would be happy to buy it for 20€ and move ahead keeping it to work and...

    Please check what I've shared. Mate gets 13,5 volts DC after replacing the Rectifier-Regulator. Couldn't be the actual ones makes regulation of voltage?

    Check this post. Some friend who had issues with low voltage, changed the rectifier and outputs good values and seems constant. Thanks mate https://www.orangetractortalks.com/forums/threads/dynamo-b7001-low-voltage-what-to-do.8564/page-2

    Never understood well AC and around it :) What I'm afraid even with low current (amps) is to deliver 25volts to battery. Wouldn't that kill it?

    I will go thru diode testing ASAP to confirm that, thanks. But then you mean, all is working fine then? Is it normal that Rectifier will give around 25v DC then? Or with a NEW and FINE Rectifier I should get a more stable DC voltage and around max 14,5? And if I buy one of those online...

    Not sure inside Dynamo but there are some connections not as you say, and also not according to wiring diagram. Actually White goes to G2 in Light Switch and Yellow goes to S, which is also connected to AC input to R-R. The brown yes goes to other AC input in R-R. Light Switch: Off : I believe...

    Thanks for the replies :) 1) The checking out of AC outputs from dynamo/alternator I gave above were taken with the 3 wires disconnected. Brown with Yellow and Brown with White gives AC around 5v in idle to 20v full throttle, in each. So I imagine, if I measure both AC inputs of R-R those...

    Not sure if someone can confirm it's normal to have such AC values coming out from dynamo and at the end I should have to replace a faulty Rectifier...

    Not charging - Kubota B7000

    Hi all, thanks for your replies. Already helped even I've red those now. Not sure I wrote this before. This is very used and bought it some weeks ago. No experience with trators :) Well, it's B7000, and I've found wiring diagram. It's B6000 but similar the same 100%. Yes, I believe the...

    I believe its original wiring. Lamps are not working but not important unless causes issues with battery not charging. And found one fuse box (I can see 2) without fuse. Could it be related? Thanks

    Yes, sure, have done it. Battery was taken out and directly to maintenance charger ;) Thanks

    Not charging - Kubota B7000

    Hi. Just bought an old Kubota B7000. Had to buy a new battery has came without it. Just checked there's no voltage above 12,5 with engine running, meaning there's no dynamo/alternator working. Or cabling or regulator, I guess. I have multimeter and can see 3 wires, white, brown and yellow coming...
