Can I remedy this stator assembly?

[sutor623]

Just wondering, resistance-wise she tests out good, but looks fried on two poles. Can I just recoat the two poles to prevent a short to block? All the wires are intact, I just dont see spending $200 if everything is working fine. Only reason I saw it was a routine timing belt job.

Sorry guys, didn't realize that I didn't post a photo. Wires are intact and look okay, resistance is in spec, just want to prevent it sending surge into the block.

Where did you check the resistance? The windings may be within spec for resistance to grounded metal, but could be shorted between turns on the same winding. I don't know what the spec is though for the resistance of the winding itself. Recoating the winding serves little purpose if the winding is shorted between turns. - Grandad

Hard to believe that it is charging as it looks toasted.

If it ain't broke........ cause you touch it and it will be.

Start checking on a new stator, CDI shouldn't be that expensive, that is a very simple stator.

Charlie it seems like it is charging. And yeah unfortunately they are around $200. '67 is the only year they used this stator as far as I could find.

1967 Merc 650 by the way. Well, there are only 2 wires coming off of this thing, and I checked resistance between the two. Spec is .35-.45 and I was reading .4ohms on my tester. Are these wires supposed to be insulated individually or all as a bundle (on each turn). Also how do you guys feel about me handwiring this guy up on my own?

Re: Can I remedy this stator assembly?

What do you have to lose if you try to re-wind and it doesn't work? Not much. The wire used is lacquer coated and is called annealed or bell wire (hazy memory). Try a starter/alternator shop that re-winds for the wire. Orientation or wire direction is very important, make sure you re-wind exactly as original. While you're checking shops ask if they can re-wind - Might be the best choice. Good luck.

Thanks buddy, I think I am going to do that. I know a guy that rebuilds starters and alternators, so I may give that a try. He'd charge more like $50. The places online charge $200 and require a core, so I have to pay shipping there, and back. And what if it ended up getting lost! Mercury only used this particular stator on one motor for one year!!

Re: Can I remedy this stator assembly?

Oh and a few other things. Do you have any idea what guage wire they used on these things? And does it need to be annealed copper? All of the annealed wire that I can find is not lacquer coated (or is it and I just cant tell?) I may see if I can find it online.

Re: Can I remedy this stator assembly?

So guys, anyone got an idea what gauge wire this is? I went to radioshack and didnt have the stator with me, but the wire is either 20Ga. or 18Ga. What do ya'll think?

Re: Can I remedy this stator assembly?

A place that rebuilds starters/alternators should have the wire of the proper gage to sell you, I tried to wind one of those and it takes a lot of skill and maybe a trick that I didn't know.

Gotcha, well thanks for the input man. And thanks again for the spec in my other thread. This stator is a simple one strand setup, so I think that I can handle it, but if I go up there and he wants an extra $20 to wind it Ima let the pro do it.
