Re: Dnepr mt11 alternator woes

Yeah I get what you're saying. No worries! This is a hobby vehicle for me, and even though I like tinkering on it, I'd rather do "fun" stuff than replace the same bad part all over. Example, all wheel bearings and stearing head bearing are SKF. I could replace with russian parts, but would have to c...

Re: Dnepr mt11 alternator woes

The bike will most definitely stay stock or close as for any foreseeable future. No extra lights, heated grips etc. I do however wish to replace broken or bad parts with higher quality replacements. If I where to buy that alternator you linked, can/should I use my original alternator sprocket? I do ...

Re: Dnepr mt11 alternator woes

Thx Claus. I will do some tests on the diodes before ordering a new rotor, to make sure I don't need to order a new rectifier unit as well. Ural-zentrale has a new rotor in stock for 55 euro. I might try one and hope it holds better quality than my stock one. I don't really want to rewire the bike a...

Re: Dnepr mt11 alternator woes

If you want to check the alternator rotor: it should have 10 Ohm resistance between the two copper sliding rings (carbon brush holder taken out ) and no continuity to ground. I get no reading at all when measuring between the two slip rings. No continuity to ground. The three phases of the stator s...

Re: Dnepr mt11 alternator woes

Hi Claus. No, I unfortunately did not do those tests. I shall have to remove the alternator again.

I have solid 12v power on the exciter circuit. My wiring loom is new and checks out ok.

Thx. I'll get back asap.

Re: Dnepr mt11 alternator woes

Hi fellas. I got my alternator back together with new carbon brushes today. Everything mounted up and a healthy battery. I still don't have any charge going to my battery and the charge light is on permanently when I turn on the key. What else can be measured on the alternator? Diode pack? Alternato...

Re: Dnepr mt11 alternator woes

Got My alternator separated today. One of the carbon brushes was split in half and floating around in there. That should be the culprit. I will order a new set and give it a try. I'll let you know the end results.


Thx for helping out!

Re: Dnepr mt11 alternator woes

Yes, there is a slot in the drive gear and a key on the shaft. Not sure if the key is press fitted or how it's attached. I can take a picture if you like.

Re: Dnepr mt11 alternator woes

Yes, I'm referring to the fold-over washer. Luckily, I have a castle nut and a box of cotter springs. Will rebuild it with one of those as well.

Re: Dnepr mt11 alternator woes

Thx Propwash, I will try that tomorrow. Concerning the generator. I found out that the gear was not solid to the axle, it could spin a bit from side to side. Lockwasher was applied, but perhaps poorly. The gear should move I unison with the fan right? Without any play? I tried to split the generator...

Re: Dnepr mt11 alternator woes

Hi. I have now conducted the test described by propwash. It gave positive results according to the guide. This would then indicate that my generator is bad after all. I shall remove it from the bike to check for wear and do some more tests on it. Will probably ask more questions later. One quicky th...

Dnepr mt11 alternator woes

Hello fellas Me and my dad have been rebuilding a 1989 dnepr mt11 during the winter. We got it working and driving beautifully about 2 months ago and have been enjoying some nice rides in our local area, longest ride around 200km. The bike has only 8700 km on it, and it runs great. However, yesterda...
