The price of new ones makes it a pointless task repairing

Does it have a detachable cartridge with brushes and rectifier? Could be less than twenty quid if it does

Post a picture of it. Someone will be able to identify it. Don't make the mistake of searching for a specific siromer part

Anything will do. Just buy a cheapo from motor factors or ag parts merchant and cobble it on
many from a basic machine will fit in its place.
as an example, i reckon this would fit

My experience, happily limited, is that Chinese kit like this is so cheap, it just isn't worth repairing.
Usually a few quid off eBay...

Thanks Dave. The tag says it's 14 volt 350 watts. There are four connections at the back. Any help appreciated.
2JF350 is the part number but nothing much comes up on a google search, Aliexpress sell a 2JF200 though which looks the same? might have to wait a long time to get it though.

seems a lot of connections? what do they all do?Thanks Dave. The tag says it's 14 volt 350 watts. There are four connections at the back. Any help appreciated.
Many thanks all. The Aliexpress looks a very likely source of something suitable.
From the Siromer wiring diagram, (alternator is 31); one wire goes to the ammeter (14) and the other three to (what I presume is) the voltage regulator. There must be an external one, as Siromer supply one for this and other models.

Thanks W - that's a clearer diagram than Siromer's. Definitely a volt reg separate from alternator.
Hi L - looks like one to ammeter and other three to voltage regulator.

Unless you want to figure out the voltage regulator and alternator and order both, I'd buy an internal voltage regulator alternator and get rid of the external voltage regulator. Wire #4 goes to the big B+ output terminal. Wire #41 goes to the excite terminal to make the battery warning light function, unless that's an LED, then it might not supply enough amps to excite the alternator, and you'd have to use the "reg 10A" wire to excite the alternator) Wire #9 off the alternator appears to be Earth since the other side of the flasher is B. The voltage sense terminal on the new alternator can be run to the "reg 10A" if it's not needed for excite, or hook it directly to the B+ output terminal along with wire #4.
