Went to switch on my George today and it barely kicked over and died.
Further investigation revealed the issue, looks like the windings are just staked with the spade connectors which appear to have worked loose, arced and melted away the wire.
I was contemplating repairing, as the windings and armature test fine, but after scraping away the outer shellac, I discovered the wire appears to actually be aluminium!
Silver all the way through, doesn't tin with solder.
This is a new on for me, and very annoying as the machine hasn't seen much use at all and has been well looked after.
I can't see an easy way to repair it, and although a new motor isn't prohibitively expensive I can't see any reason why it wouldn't just fail in the same way.
The other spade connector also shows some signs of arcing so probably not far behind - no epoxy on anything, just a punch down connector on aluminium wire presumably subject to vibration - what could possibly go wrong.
To say I'm unimpressed is an understatement. I'm wondering what the failure rate is on these.
I know its only a vacuum cleaner motor, but is it just me that thinks this is a bit crap?
