What's the difference? Isn't it as simple as connecting the motor wire to the other lead of the capacitor - the one that goes off to the field coil?
It's a little hard to tell from the pictures, and I'm not familiar with how suppressor capacitors are normally wired, but it looks to me like it is in series with the motor. This is my guess: LINE -> capacitor -> field -> armature -> field -> NEUTRAL |

Well you only need to keep the one capacitor contact that is attached to the field coil wire. Scrape that capacitor gunk off, leaving only the one contact, put it back where it normally is, and fill the capacitor's hole with silicone. That will keep the remaining contact from moving. Then simply connect the line wire to the remaining capacitor post. No need to cut wires or anything. In fact, it looks like they designed this machine to have the capacitor bypassed whenever it was necessary. Otherwise, they would not have had a blade connector on the capacitor terminal that goes to the field coil. I think the designers intended for you to leave the capacitor in place and just pull the line wire off of the first capacitor connector, and put it on the second.
Also, soldering is very easy. The trick is to get yourself a can of flux and use it. I can't tell you how many professionals I've talked to that dismiss the idea of flux, despite the fact that they use flux-core solder. |

Why do British/European vacuums have suppressors in their motors? What do they do? |

MadMan is correct. It might be because of the fact there is a lot of town houses and rowhouses in England and Britain and everyone lived close together. So if someone was vacuuming in one house, it might disrupt the television signal in another person's house, if someone was vacuuming in one room, it might interrupt the radio in another room of the same house, and so on and so forth. Like most electronics they rot as they age and then the suppressor turns into an insulator, traps current and heat, then it explodes.
American (and I also believe Australian) vacuums never had suppressors fitted - so this was something to do solely with UK government. Obviously with different types of non-analog electronics now and more electrical isolation within appliances, this issue has long since been obsolete and the suppressors are no longer necessary. In situations where they can not be removed or cut off, I would just put a new capacitor back in there to replace the blown one and call it a job done. |

Well, in the world of small engines, some spark plugs have an R in the number. (Ex. RJ19LM vs. J19LM) The plug with the R would prevent radio interference if someone was cutting their grass near a TV with the bunny ear antenna. |
