Pretty simple really, 12V+ from ignition switch or the switched fuse (easier), 12V- from an earth wire to the body, signal pulse wire from the dizzy side of the coil. Easy peasy... |

They should just be thrown in the bin. |

Keep it clean, neat and secure. Follow existing cable runs where possible. If your just starting with electricals and you have a mini then you have much to do. One of the biggest problems and hardest to find intermittent problems with cars period is poor (or good for a live wire) earth. Electricity doesn't flow where you want without good earth. Buy a can of battery terminal paint/sealer make sure it's the DRYing sort (like OE) as the other is messy and painful, next buy something to clean back metal - steel wool,S/S pot scower, wire brush, wet and dry 120. Start with your battery, remove the post clamps, clean clamps and posts, then place your battery on charge (using a modern charger to avoid cooking the battery) leave battery disconnected. The battery strap to the body needs inspection. I cleaned away the mastic, rubbed all surfaces back to shinny metal, then re clamped and painted. Move to the front of the car and identify the power cable mount coming from the battery, remove and clean, reassemble and paint. Follow this process all the way through your system till you come to the point where you want to add in your tac power then follow the supplier instructions, they should say to connect to the ignition circuit which is only live when the car4 is ON, never attach to your charge circuit and always use a fuse (existing or new). To earth the Tac use an existing OE point, undo, clean, assemble, paint. Once finished you then reconnect the battery and paint the terminals. Now go clean and reseal all the earth points you can find. Other - Electricians tape/pvc tape is no good in a hot zone as the glue fails. if it not in the engine bay or against the bulkhead/firewall it should be ok Use heat shrink on joins. NEVER use a screw/self-tapper as an earth or anything, you'd just guarantee problems for you and the poor sod who runs over them as they fall out. Any electrical lead that you find where the cable is sloppy as it enters its end connector is most likely a sign of deterioration by vibration. You'll find a few of these as you go through your car, make sure you secure the cable to an element close by or heat shrink the cable/terminal or both. Clean the distributor rotor button back to shiny and remove the white crusty stuff from the distributor cap terminals. Doing an electrical clean and secure on a mini is as important as changing the oil. Youll have a higher and smoother reving engine, a radio that doesnt crackle as much, a taco that doesnt jump, lights that work well etc. |

Thankyou to all who have replied, l will have a crack at it on the weekend, l might try and sit down with a workshop manual prior to try and get a understanding as any electrical work to me is foreign, one question how do l establish what is 12v+ at a switched fuse/ ignition switch? |

One of the fuses is live only when ignition is turned on. This is the bottom one. Connect to this. The top one is live at all times. [edit] this assumes fusebox is wired as original, unlike a member's Mini Deluxe I played with yesterday. They were reversed. |

You need a test light. A small multimeter is better but a test lamp is simpler and cheaper. I think I paid less than $5 for one at Autopro earlier in the year. This looks like a small screwdriver with a bulb in the handle and a tail with a an alligator clip. You attach the clip to earth (basically any nearby metal bit of the car) and touch the point of the test unit to the bit you want to test. If its live the bulb lights up... simple. So in Doc's example above if you touch the ends of the top fuse , the light will come on. The bottom on will only light the light if the ignition is switched on. While advice like Doc's is good ...and so is the wiring diagram in the manual... they only describe what "should" be. The test lamp will tell you if what should be happening actually is... if that makes sense?? Cheers, Ian |

Here's a simple one - http://www.jaycar.com.au/Test-%26-Measu ... s/p/TD2049 I lashed out and bought this one that has voltage measurement and other functions - http://www.jaycar.com.au/Test-%26-Measu ...

Well I managed to not stuff it up, had a multimeter, but no idea how to use it so a few YouTube videos and l was away, even soldered and heat shrinked my work. I still have to sit down to learn how to program it, hopefully it's not to hard. Thanks again to all that has given me advice.
