Alternator advice

[Dave O]

Can anyone advise me what size solder iron  I need to desolder the stator loom wires from the rectifier on this spitfire 1500 alternator? (See photos)

I’ve tried my 40w draper iron and nothing happens after about 30 seconds, it doesn’t seem to want to melt even though it’s at full power setting!

Im hoping to replace the rectifier and regulator but need to remove the old ones (which look pretty corroded) first.

thanks for any advice

it is probably silver solder has a higher melt  but that all looks like its had a lot of diy work done in the past life 

 

you dont need to desolder the diodes

You have too big a heat sink. If you do need to remove those soldered joints, you need to get the whole pack warmed up or you need a small gas torch which can put enough heat in very quickly without it being conducted away.

As the rectifiers had it you can just cut its connections which should make it easier to desolder. Of course then youve still got to connect the new rectifier but at least you can tin that with solder first...

on recon alternators we had some good experience of when a diode had failed they just cut the wire to that diode 

reduced the output ability but the warning lamps stayed off ...nice box, crap inside it 

wonderful !!!!!!
