The Haynes wiring diagrams are not perfect but are fairly consistent and they generally build on the previous one as more features were added. Find the one that has the date range closest to your car and study it carefully. Use the earlier diagrams to help decipher circuits. As for added or replaced wires, nothing else to do but trace them. The hardest part for me is finding the factory in-line fuses and correlating them to the wiring diagram. It helps to work with photocopies and mark down what you discover.

Also, I do have the hard cover version of the Haynes Manual, but the wiring diagrams seem universal and maybe not complete. My 1993 Mini has had several wires replaced, so colors aren't always dependable.

On my 1993 stock Mini I completely lost all electrical after I got it. When you turned the key, no starter, no dash lights, nothing. I could get the exterior lights when I power probed the wire connectors. In frustration, I brought it to an electrical shop. I am aware no one knows how to work on classic Minis here, but I was out of ideas. After 8 hours and $1450 they've replaced the relay box. Vehicle now cranks over but still no spark or fuel injector pulse. All fuses are good and all fusible links are intact, even in front of the starter. Wiring from relay box to starter, fuel pump and ignition coil are all intact. No injector pulse signal or spark when cranking. Ignition coil voltage is low - should be 9-11.5 volts but is only getting .5 volts when cranking. Electric tech suggests this could be caused by a bad trigger, short to ground, or bad ECU. I'm completely frustrated, looking at sending the ECU to Mini Spares to be refurbished. The other Mini I purchased doesn't run either. Started out just getting spark on 2 cylinders. I installed a new Lucas ignition coil, distributor cap, rotor cap and good spark plug wires. For 20 minutes it idled great on all cylinders and then it died and it now has no spark on any cylinder. It has voltage going to coil but nothing to the spark plugs. It has an electronic ignition but I've purchased a new electronic ignition to install. Then I guess it's a new ignition control module after that. It was always the same 2 cylinders that didn't spark throughout the beginning of this ordeal until there was no spark at all. It's been a long, frustrating month since I got these Minis, especially when nearly everything has to come from the UK.. I've purchased some items from DJs in Florida. Any help would be great. Thanks in advance, Steve

Join or ask Minnesota United Minis. They hosted the 2009 East Meets West Mini Meet so they're not all about BMW MINIs.

This board is very smart and helpful. Remember everyone will have a different opinion or solution; you will have to decide who is right and who doesn't know what they are talking about. You will find that auto parts stores won't even know what you are talking about because the mini is not in their computer. Get your self a Haynes manual. Become an expert.

I live in Northern Minnesota and need some repair advice from other classic mini owners in the state. I recently purchased 2 classic Minis from the UK and I need help sorting out problems with both of them. Especially in this area of the country, these vehicles are unique and difficult to find advice or repair experts for them. The questions are mainly electrical. Any help would be appreciated. Thanks in advance.
