| Post subject: | No control box/voltage regulator?!??!! |
Does anybody else have a mini with no control box/voltage regulator? I have just replaced the loom in my mini with a uk one but when I connect the battery terminals the motor starts, even without a key in the ignition! okay, I'm guessing that is not good..... I pulled the white/red wire from the solenoid - ok now it doesn't crank the starter motor so I went looking at the ignition switch and rechecked the wiring diagram. It all looks wired up right but I don't seem to have a control box or voltage regulator..... I remember when I pulled the old wiring out there was a big tangled mess of brown wires all soldered and twisted together that were just wrapped in electrical tape in the engine bay. I thought it was dodgy at the time but now i wonder if they were supposed to be going to the missing control box. the car still ran so I thought it was just more evidence of the PO's dodgyness. So, do I just take most of the brown wires off the solenoid a la the old wiring, or should I try source and put the voltage regulator in there? |

Since 1972 or so, every Mini had had no voltage regulator. it is built into all the lternators now. The tangled wiring you have is obviously where they have done a `regulatorectomy' to convert (from generator) to fit a current alternator. With these there is a thick brown wire (or 2) from the solenoid's battery terminal to the alternator, and a thin brown/yellow wire from the alternator to the ignition light in the speedo. That is it... |

Regulatorectomy.... Love it! So my eager starting wiring problem is probably due to something else. Unless anyone has any ideas i guess i might have to concede defeat and call the auto electricians. |

There's obviously a mismatch somewhere. The solenoid COM wire (i.e. the wire you momentarily send power through to trip the solenoid) is obviously connected to an always-on power source or it is shorting on one enough to switch the solenoid over which in turn sends power to the starter motor. |

You were right Tom, I searched through the forum and found a post '72 wiring diagram and made the necessary alterations and I think I may have sorted it. I'm just waiting fir the battery to recharge. |
