Alternator Help

[Darren]

Hi guys - looking for a bit of help/advice.

I've been given a newly refurbed series 2 alternator, which has a little bit of a problem with it. When it was rebuilt - someone forgot to actually attach the main power connector block and after a short while it moved about, arced everywhere and the results can be seen here

Now with my credit crunch economically minded head on - can I clean up the damage and re-attach this part properly, or is it likely that it's done far more damage to the rest of the unit? Is it better to try and source a new part, or indeed, chuck the whole lot out and get a new one?

Thanks all!

If it's just the alloy damaged you could try building it up with alloy welding rods or even try that plastic metal and file it to shape.not like you to be stuck.

Hi John, that was my thinking, but I guess I just wanted some confirmation. The unit doesn't look particularly complicated and I'm sure that's all thats needed.

Thanks!

Do you realize there is no pic in your post Darren? At least, I don't get one.

I was running some software that was keeping me from getting the pics. I didn't figure it out until I realized I also couldn't access my FTP space. So, the problem was on my end.

I can't see any pics either...

Sounds like you have the same sort of probs that Will had - pics are still there mate

Any joy now?

Darren,

I have seen that same scenario on GM alternators. There is a double ended stud with a longer leg to the inside to go through the rectifier. On the outer side is a short stud with a washer type section. The inner nut gets tightened by someone with a nut driver by hand. The outer gets tightened by something that torques it down a lot more. When someone tries to loosen the outer nut the stud spins and the inner nut on the rectifier comes loose. They run the car and the poor connection creates resistance and then gets hot.

Nearly any of the rebuild shops would carry these. WAI is a huge company here that makes a ton of electrical rebuild parts:

Hi Scott,

Thanks for that - found it here

How do I go about ordering one?

Thanks mate

I would try a local rebuilder or electrical shop first. If you can't find one over there let me know and I can probably find one over here. There are really not that many mfrs out there. WAI only sells to mfrs and rebuilders.

I would call/email their Europe office and ask who they sell to in the UK.

That is how I found these guys.

They are not too far from me and they have darn near everything. They had the parts for the Bosch that died on me a couple years ago.

On a side note, WAI is known for being a leader in extremely high ethical standards. I have dealt with them a few times and they have always been great. Read these links for more:

Thanks Scott - much appreciated - I've dropped thme a line and will see how it goes. Would be really handy to have a Wai supplier in the UK!

Cheers

[Darren]

Update after doing a bit of digging about - done and dusted. For UK sources, I recommend www.alternatormart.co.uk - very friendly servce for components or replacement parts.

Should have my new rectifier tomorrow! Thanks again for the Wai pointer Scott to get the part number.

Cheers!:)

Darren,

While you are in there take a look at the prices to replace the bearings and brushes. Even the rectifier may not be too expensive.

I did the regulator and bearings on mine for $35 IIRC.

Glad you found someone close by. it seems such a waste to buy a new/rebuilt when repairing the one you have is so easy and cheap.

Hi Scott,

The unit I have was rebuilt but the rectifier wasn't attached properly. The rest of it is as now with new painted case and new bearings. I'm with you mate, I'd rather do something meself than pay someone to do what I can do! ;o) A skinflint in other words!!!:)
