Henry lights up but no life

[lostinthelight]

I bought a Henry complete with tools at a boot sale for 2 quid.
I was told it was not working so when I got home I took it apart and one of the brushes was stuck in the holder.
Worth a look as they were still quite long

thanks for the eBay link. Can I take that my problem points to a faulty PCB?

 

[rocks1]

Yes u can.

 

[Jupiter01]

Ok...
£15 and 2 hours down but no Henry unfortunately

I replaced the PCB as per suggestions above. It wasn't obvious where the wires plug into the new PCB as it is slightly different to the existing PCB.
I initially tried the following:

After powering up, there was nothing. Not even the light that I had initially. I may have heard a trip-type sound but not certain.

I then tried the following configuration of cables:

Nothing at all again...

I then regressed back to the old PCB and wired it up as it was. I now don't get anything with that either whereas previously I had the LED lighting up as I explained initially.

Where next guys?

With the new pcb you would have got a new wiring diagram with it. You got to change two wires round. From memory I think it's black and brown. Post a pic of the wiring diagram. Sounds like you blown pcb up by doing the old wiring the same.

 

[Jupiter01]

ohhh...
but why doesn't the old pcb work insofar as the led anymore?

 

[rocks1]

The pop your heard was poss the small led light in the switch that blew.

 

[Jupiter01]

That sounds plausible. I will reassess things when I get back in tonight and report back. Thanks

Have you checked the fuse in the plug since the pop?

Can you not bypass the speed control board and run it on full power? as long as the motor is rated at 230v I can't see any problems.

(These days some vacuum cleaners come with a 110v motor and use an electronic control board to limit the power so that these motors can cater for USA and European supply voltage and only needs an electronic control and 110v motors also use less copper/aluminum windings.

 

[Jupiter01]

how do I bypass the PCB?

 

[rocks1]

I explained how to bypass the pcb back on page one of this thread. The two white wires on the motor go straight to the on off switch ignore the two speed switch and remove the pcb totally. Then the on off switch just has the input of power and straight to the motor.

Update: I opened up Henry again (4th time and still counting...)
With the aid of the diagram that came with the new PCB, I re-connected the wires. Here's the diagram:

and here is how the wires are now connected:

The plug fuse is fine. It hadn't fused. I have replaced this and verified that this is the case.

After powering it up, no light or any sign of life. Any ideas guys?
I am now proceeding to directing the motor as suggested by @rocks1 but disappointed that the PCB replacement has not fixed my issue. I welcome any thoughts.

More on the motor directing shortly...

 

[Jupiter01]

I've now directed the motor. I assume that either of the white cables coming from the motor can replace the Live and Neutral on the on/off switch. I've done this as shown below:

powered up and nothing
No sign of life.

Where next guys? Argos?

When you put the wires on the first time it was the wrong way round that's why the pcb has blown. Just wire it straight from the motor to the on off switch it will work on hi speed then not the very low speed. The pcb are very common problem it blows the little speed resistor on it and cannot be replaced.
