Hi Chaps! Thanks for caring..... :thumbup: Andy. Thanks for the guide.... Lots of self help info there. Dave. "Your" Warco brushes are 8mm wide, the same as the Arc Euro ones I have fitted. Stuart. If anyone can make it worse, I'm sure I can! John. I've got a 60watt test bulb, somewhere...... Can't help you over the speed control pcb. All I know, it's Chester's original. (American?). Kenneth. Thanks for the part no. and agreement with the consensus of opinion. Can't do anything until tomorrow afternoon. Then I'll give it a try, as instructed. Household/ workshop wiring, I can manage..... But when I come across pretty little coloured bits inside smoking boxes..... I'm completely smockravelled.... ::) David D |

Dave SD Somewhere in my shitpile stock of spares, I have a fair number of motor brushes. Will have a shufti tomorrow. Are they just black carbon things, or are they copper impregnated. ?? Usually obvious, they look coppery :lol: I may have some larger ones, easy to reduce them with some open coat garnet paper or similar. Mucky job ... :( but done it before ... Dave BC EDIT Mine is similar to this ... http://kbelectronics.com/manuals/kbic.pdf Have a look elsewhere on their site. You may well have a KB controller if it's US origin, see if you can spot the one you have. Just remembered, I have a KBLC240D .. see attached Off to ZZZZZZZZ's |

Hi Dave , I think you have had a short circuit from earth to the filter or the wiring to the speed control but just incase , I've just had a look through my collection of manuals and circuit diagrams and found a low res copy of the KBIC circuit and manuals inc .circuit of the KBPB and KBET controllers they may help if your controller is faulty ? it looks like they should take little current so with the series connected lamp and no motor connected , the lamp should be dim at most ,if not out John |

Wow, there sure are a lot of people here to help you, David. All I can see is the smoke got out and black stuff got in. That's it for my diagnostic genius. Good luck getting it fixed up! Sneaky stuff, that 'tricity. |
