Re: Is this dead or can be repaired ?

I've tested everything today.
The alternator is still alive !!!!!

It is charging batteries at 14,4 in absorption mode.
Hope it will do his work for few years now :-)

Changed the 6 diodes.
It seems the alternator is still alive.
Tomorrow I'll put it on again and will test it.
Hope it works fine !!!

Will let you know ...

So you can try to find one diode from an electronics house, or you can try to find a complete diode frame set from a wholesaler. Either way will take some time and sleuthing unless a local alternator shop can hook you up. If you can find a tv or electronics repair shop, they may be able to locate the one diode for you as well.

If the diodes have any numbering or marking on them, that can be looked up to find out what they are.
Many thanks.
There are no numbers on the diodes.
There is only "USA" and a letter "R". That's it.
I'd like to buy the complete set of 6 diodes (3 positive + 3 negative).

Re: Is this dead or can be repaired ?

Now, I can post the picture of the dead diode.
Anybody can help to find what kind of specs it has ??

I only know that it should be 200 V.

Thanks a lot

Re: Is this dead or can be repaired ?

Thanks.
This is what I'll try to do !!!
I really do not accept to pay a simple electronics item ten times its real price.
The marine market is very often without rules !!!
Hope will find the diode and change it without damage the board.
Will let you know ...

P.S. - anybody can help me to know which diodes I've to look for, and where is possible to buy them (not at AmplePower) ? Thanks.

Unbelivable !!!

Is it possible to find compatible diodes and change them on the board ?

Thanks.
That is what I would do, diodes are cheap, even top quality ones. I would get the numbers off them and start checking electrical supply houses and electronics repair shops. Last time I swapped out a diode, I stopped by an electronics repair shop and chatted with the owner, he gave me the diodes, they are not hard to solder in either. Just use a low wattage soldering iron. This is where a cheap soldering iron is often good, as they tend to not be very powerful.

Check to see if you have continuity on the rotor and all stater windings.

Also check for blown diodes. Usually just one goes.

The slip rings look OK.

Check to see if the bearings run smoothly, cheap replacement item.
If you were in Grenada I would tell you to take it to Al Bernadine who would soon have it working again.
I took it today to an electrical shop.
It looks like the continuity is ok.
The diods look ok.
The bearing needs to be changed.
There is on cable that connect the diods that looks broken (fired).
I hope it can work again !!!

It would be nice to be in Grenada instead of in Rome ... and working

Thanks
