scorpion component ID

[wilo76]

My black and decker scorpion has packed up and is out of warranty and iv just disassembled and tested it with the multimeter and there is power right through the brushes to the motor but stops right where the black capacitor type thing is (see pics).this component is connected to the left side brush only . Can any one ID this component ?and is it possible to fix/bypass it .

Hi Looks like an RF Choke to help stop radio interference surprised that you are not getting a circuit past it as usually they are just a coil of enamelled copper wire wound around a piece of ferrite rod.
Try shorting it out and see if you have got a circuit. B&D don't make the best or most reliable of power tools check out the trigger as well especially if it's the variable speed type.

I went there 2 days ago for some heat shrink and a deans connector ........their reply was "what are them":ack2:

ok just retested with an electrical screwdriver. there is power from the trigger to the lower half of the motor and to the right side brush , but the top half of the motor including the left brush with the choke attached is dead

Short it out it will work fine it will just make a big more electrical noise

It can be repaired. Just find the wire gauge and wind some wire round the core. Its only an electromagnet. Or you can count the turns and so long as we know the rating of your drill we can find a replacement.

Can you give the full part number of your scorpion. Black and Decker do an exploded parts list. Haven't found your component yet.

Its the gel tech scorpion - model KS890GT type 1 - 400w - 50Hz . Does this component stop the brush working ? as there is no currant detected before this on the motor . the way it is set out is .......the right brush is connected to the lower half of the motor and all this is live once i depress the trigger . the left brush is connected to the upper half of the motor and all this is dead even if i depress the trigger . hth:cheers2:

If it is a coil and in series with the motor then it will stop it working as the current can't get through it. I'll try and find the replacement. If it is in series then you can short it out with some fuse wire. If it was in series it will work, if not the fusewire will blow. Don't be too close when you tru this and use an RCB.

Looks like it might be one of these.

BDE-573185-00.3

That's a brushbox and choke. I'm not sure from a distance, but it looks as though it will work without it. Not sure why it would fail though, unless it also acts as a safety fuse. Might be an idea to get another or repair the existing one. It's a cheap part. You could certainly short it out to see if it gets the saw going. But there's probably a reason why it failed, and that same fault could happen again.
