What exactly do you mean by this?

Your best bet right now is to take @marconi up on their generous offer of help

I was told that many a time, this person has found an appliance tripping, so they take off the earth and run it for a while to dry the moisture out. I was dubious as they were not an electrical expert by any means. Hence the reason why I asked around first. Hopefully drying out the motor fully will be enough to save it exactly as marconi said.

Do not do this, you will be putting yourself at significant risk of electric shock which could kill you or someone else.

The earth connection is there to ensure your safety in the event of a fault. You know that there is a fault in the appliance because the earth and the protective devices are doing their job and preventing you from being injured.

If you remove the earth connection and energise the machine then you are removing the thing that is keeping you safe from harm.

This is the sort of thing that you would see someone do on TV and think to yourself "I can't believe anyone would be that stupid"

Well drying it out in the oven plate warmer did the trick. Powered up nicely with no load, now to spend the day renovating it seeing as I've pulled tge garage apart, honestly be easier to buy a cheap clarke comoressor and chuck it every 10 years.

An update on my compressor; I think my motor is trashed now, started up the weekend and it made a racket and started smoking. I think the water ingress took it's toll on my cheap machine mart motor. But then, no motor should have that much water in it. Should have fixed the roof first eh!
So I'm picking up a replacement motor..
Meanwhile, it did a good job spraying my old Singer and now a Land rover.

Picture of my latest rebuild, complete with thatcham approved security dogs. Again, not the best paint job but suits the vehicle perfectly, easier to paint as I didn't want it as shiny. This is a classic next year 1985. So the compressor motor has done a good job so far.
I'll be painting the inside of my house next using the compressor. Have 60m line and separate small receiver. So asking dumb questions on another forum about that now.
Meanwhile, I must visit machinemart and empty my wallet. first name terms there. Maybe when I swap out the motor, I'll strip it and find out why it smokes, could be something simple, but I've convinced myself the water damage trashed it.
