Not Charging

... and reclock them to the right position.

??? What's this?

The way the mounting ears are placed on the alternator. You can take the bolts out and spin it so that it is in the position it needs to be. Like on say small blocks from back in the day. The alternators all mouth very similar. A bolt through one spot and a tab that tightens it to the adjustment. A full size truck with a 350 may have the adjuster tab at the 11 o'clock position I believe. The same truck in a 6 cyl application may be at the 2 o'clock. Everything is the same but that tab and maybe the pulley. You can swap the pulley of their bad alt onto the new one if the diameter is different and you take the bolts out and turn the case half part so that it will match up correctly. These are just made up positions. And it's been 20 years since I did one and in the year and a half I worked parts counter I may have only done it a few times. I can't remember what I did last week at some points but this is how I remember it.

Thanks. I didn't know you could do that.

I would almost bet that the larger alternator would fit. I am sure the 35 amp version would fit. ...Probably would take some research. I would look up each of those alternators or listings for the correct application...

Thanks. That was my thinking too. The YM2610 has the 35A version. I was hoping for a 50A or 65A to replace it.

So, you are RIGHT. This fits yours and mine. LOL

I pulled the regulator off the non running 186 to take to the farm this weekend to see if it's a bad regulator causing my no charge situation. I figure I have it, and I assume it's good and it's free to try so why not.

I believe they are different regulators. The 186 has a dynamo.

Agree, not similar regulators.

Ahhh, your right!! I forgot about that. I was even eyeing that tiny little thing , thinking man I wish it was an alternator. So we're sure it's different? I guess I can go to hour and look.

Edit: yep y'all are right. I looked them up on Hoye and different part numbers.

I would almost bet that the larger alternator would fit. I am sure the 35 amp version would fit. I can't say for certain. Probably would take some research. I would look up each of those alternators or listings for the correct application...cheap china eBay alternators even and get physical demensions and then compare to Rock Auto application for the 50a datsun/nissan applications. Also paying special attention to how the alternator is clocked as well. This is not as big a deal. I worked at a parts store and if we were out of one part number alternator for say a certain small block chevy application, we would look up another, as long as connector and amps were same we would pull it and swap pulleys if needed and reclock them to the right position. My point is that can be done. If connections are in a different spot on the body you may also have to lengthen it a few inches but that's not a big deal. Cut it and use marine shirk and heat shrink connectors and reattach.

I am positive there will be another application you can look up.

Ok looking back Into this. I went onto Hoye site. Pull up the 186 regulator. Look at all the part numbers it replaced. The last one is xxx-77710 . That is the same number that the VR for the YM 2000 lists as the part number that their part replaces. So saying it in a less confusing way. Both Hoye's VR listings list the same Yanmar part number as what it replaces. The listing for the 186 lists way more part numbers it replaced vs their listing on the ym2000. I believe it's the same part. There is some wording that there is a new and old style VR for the 186. One had 2 components and the main one had a 4 prong plug and there was a seperate black box beside it that is now in the new one and if you had this 2 part set up you need a conversation harness. But if you have new style 6 pin connector it's a direct replacement. That said the 186 I have had a 6 pin plug like the ym2000 so this should work on the ym 2000.

And dear Watson, It's elementary understood. :drink:
