4 core appliance Wireing dilema

[elexier909]

Hello all

My first time posting on here so be gentle lol.

I have attached a picture of a bit of wire from a appliance I am trying to wire a plug back onto.

Now normaly It's just 3 wires.

Live, nuteral and earth.

This wire has Red, Yellow, Blue and Brown.

It used to have a plug <it got the snip for some reason> and I would like to re-attach a plug.

How does this thing get wierd up.

I have enclosed a picture.

If it helps this is a wire for a bed that has 2x vibrating pads, and a motor that raises and owers the head end.

Bed is worth 300 quid so getting a plug on it will be a huge help.

Thankyou in advance.

That end (in particular the rubber moulding) doesn't look like it's just had a plug snipped off it, it looks more to me like it's been ripped out of some kind of controller or power adaptor.

It doesn't work like that - all posts are taken on merit.

It used to have a plug <it got the snip for some reason> and I would like to re-attach a plug.

Before, or immediately after cutting it off and before throwing it away did you make a note of which wire went where?

Was it a regular 3-pin mains plug, not an unusual one which plugged into a controller which did up/down/massage etc?

What would help would be a photo of the connections at the other end of that cable.

Have you tried contacting the manufacturer?

If it's like the last one I looked at, it was not a standard plug on the end of the lead, it was actually part of the control system, and included one or two relays and a resettable cutout packaged in an oversized plug body.
The relay(s) were driven by the batteries in the control pad, switching the power when a button was pressed. Once the batteries in the control pad ran flat, or, as in the one I looked at, the lead to the control pad got damaged, the relay(s) didn't operate, giving the impression the 'plug' was faulty, as no voltage appeared on the mains lead.

With that part of the control system removed, it's anybody guess what will happen next. Smoke? Fire? Electrocution? Take your pick.

I was not trying to go into details but here goes.

The bed used to belong to an elderly gentalman who has scince moved/passed on. <I do not know witch>

The lady that has moved in there now discoverd TWO of thease beds <one had all the leads ect>

This was before I met her, She sold the one with all the leads ect.

apparently <from what she has said> The plug got chopped off as her son spent 25 min trying to discover the scourse of a vibrating noise <apparently he never thought to check a vibrating bed>.

When he discoverd it he was so wound up he chopped it off.


Now if what you say is true and it should have some sort of controller that might explain a few things, I am over her house again today helping out so I will ask and see if this controller exists.

I will report back with what I find out.

Thankyou for the heads up <could have ended up nasty :S>

Some beds and chairs also have a 'backup' power supply (sometimes a plastic box full of PP3 batteries, of all things - just enough to return the bed to the 'normal' position in the event of a power failure). Maybe that would explain a fit of frustration, ripping the lead out of the battery box when unplugging the mains supply doesn't shut the thing off.

this is a wire for a bed that has 2x vibrating pads, and a motor that raises and owers the head end.

It is my guess is that the wire was not ripped out of a plug, but out of a control box.

It would not make sense for the motor and pads to be constantly supplied from the plug.

My guess is that there is a common neutral, and the other three go one each to the two pads and the motor, and the controller would have sent supply to one or more of these subject to the position of the switches. It would be unsafe to try to guess how to wire it up and fit a home-made controller without knowing how it is supposed to work.

My recommendation would be to contact the manufacturer and ask them.
