Hi, have had a George Neumatic Hoover for years (GVE-270-2).
Was mainly used as a house hoover with the occasional DIY Clean-Up. Recently started using it as a dust extractor on my sander (a couple of times) and was working OK. Used it today to clear a section of the gutter (dry waste), all going fine and suddenly stopped working just like that.
Have used an electric tester screwdriver, and tested the cables going into the machine (lights up). The switch, which lights up when switched on and off when switched off. I tested up to the motor, which lights up when switched on and off when switched off.
My thinking, therefore, is that the motor has gone, and need to get a new (replica) motor . Does this sound right or could be something else.
Thanks

an electric tester screwdriver is not suitable and dangerous to use on a vac if you have the motor exposed in case it suddenly starts up
you need a multimeter
you say it lights up but for it to work you need one to light and one to not. Sounds like a neutal fault. Does yours have the speed control board ?
Dave
The lid was off and there was no one around me. Also, I don’t go poking around in there and merely touched the exposed terminals.
It doesn’t have the speed control, only two switches, one for the vac and one for the (wash) pump.
switches go as some of them are double pole you will get all lives
cables can go. if you have a break on the neutral you will get all lives
you need a multi meter to check for continuity. you can do it with a neon but it can be hit and miss. start with the flex. make sure the brown lights but the blue does not

———————————————————————————————————
Multi Meter results.
• Both Vacuum and Wash switches set to OFF.Test 1 Continuity (moulded plug).
Live terminal on plug to live (brown) terminal on George = BeepTest 2 Continuity (moulded plug).
Neutral terminal on plug to neutral (blue) terminal on George = No Beep• Vacuum switch set to ON, wash switch set to OFF.
Test 3 Continuity (moulded plug).
Live terminal on plug to live (brown) terminal on George = BeepTest 4
Neutral terminal on plug to neutral (blue) terminal on George = No BeepTest 5
Neutral terminal on plug to live (brown) terminal on George = No BeepTest 6
Live terminal on plug to live (brown) terminal on George = BeepTest 7
Live terminal on plug to neutral (blue) terminal on George = Beep
————————————————————————————————————–Also tested various other point to point connections and they appeared to be OK.
Will cut away a section of cable, just to rule that out.

Out of interest, what was it in the readings that made you think (or know) this?
two things pointed to it
look at this simple diagram with a neutral break
plug on the left cleaner on the rightwhen you first posted you told us you were getting lives everywhere. This is a big give away. You were measuring at point B and D and got live. under normal situations without the break at E point D cannot be live
the next thing was your meter readings. you got a buzz from A to B but you did not get a buzz from C to D. Which meant you must have a break from C to Ddoes that make sense ?

Hi Dave,
Apologies for the delay in responding. The image would not show on my phone and so had to review on desktop.
Unfortunately, it doesn’t make sense as feels back to front. A break in the neutral gives a live (connectivity) response, whereby if there was no break in the cable, then it would not give a live (connectivity) response!
you are reading the live because its coming through the motor.
if you take the diagram above. the live flows from point A to point B. It then flows inside the appliance from point B to D. So D becomes live
it fools a lot of people
