In an attempt to work out why our Henry wasn't working, I unplugged one of the two white motor wires to buzz things out with a meter. Stupidly I didn't plug the wire back immediately and now returning to the Henry a few days later I can't be 100% sure where it went!
I'm fairly confident it comes from the one remaining terminal on the speed-control PCB as shown in the attached photo, but there are also two compatible terminals on the speed-control ("hi/low") switch as well.
The Henry is an HVR-200 from 2005 - does anyone have any ideas?
Unless a person has the same model/year as you have, and are willing to take it apart how do you expect to get the correct answer?
(Yes, a wiring diagram would help, but I don't have one, yes, if you are sneaky, and look carefully you MAY get the right answer) But you still haven't found out what is wrong, as it's 16+ years old, I would say, sorry Henry, it's time to go to that vacuum cleaner world in the sky. And next time label stuff and take a picture of it.

Would you hit a nail with a shoe because you don't have a hammer? of course not, then why work on anything electrical without a means of testing Click Here to buy a "tester" just because it works, does NOT mean it is safe.
Actually, I have found out what's wrong. I just need to be sure about this one wire.
So wondered if someone with the same model had experience of it. Replacing the speed PCB & switch is a really common "mod" when Henrys break - it isn't as bizarre a question as it may seem.

So for future reference, what was wrong?

One of the contacts in the "head unit" which takes power from the mains lead and applies it to two brass rings and then on to the switches/motor had snapped. Obviously until I can get the motor hooked up again I can't be 100% sure but it definitely won't work without live & neutral going to the motor, and as there was zero signs of life (no power to anything) it feels like the broken contact could be the culprit.
Again, turns out to be a fairly common fault over time according to the internet and at only £2.49 for replacement parts is around £138 less than a replacement Henry,
I haven't bothered to look, but if it's a common fault, repair is simple and it's a popular machine, you could try searching youtube videos. One is bound to show the connection you require, even if it's not about the specific fault.
I'd say it comes from the PCB and the spare connection with the blue wire attached (J1?).
The switch is a double-pole single-throw type. It has two sets of contacts in it. One set seems to be shown as shorting the blue and brown/white. The terminals on the other side would need two wires on them to actually do anything so the odds on them being part of the existing wiring are zero since there aren't two wires to fit!
If gloom had a voice, it would be me.
