I have Just watched a episode of the garage and felt compelled to do this,it was the episode where they try to get their mini started and end up changing the whole ignition system unneccesarily, they got close to the fault but bodged the repair, obviously never heard of a ballast resistor, are they really trained mechanics? this is basic stuff, or is this what really goes on in garages and the poor punter ends up forking out for a complete ignition system where it was probably a wire not put back where it should be on the solenoid.
In pre electronic ignition days, when you crank the starter there is only about 9 volts available for the ignition system, so the coil is actually a 9 volt coil and in normal running there is a ballast resistor in circuit with the coil to drop the voltage down to around 9 volts, when the solenoid is engaged this resistor is bypassed to give full spark during the cranking period as the 9 volt coil has about 9 volts supplied to it, the reason the voltage disappeared while cranking the motor was either the contacts on the solenoid burnt out or a wiring fault around the solenoid, by bypassing the system there is a risk of burning out the coil, I know I did it many years ago when I had the same problem with one of my old bangers, I am not a mechanic but know electrics.

That's all very interesting. However, the feed on cranking wasn't there, because the electrics were shot. Of course they know how an ingition system works. The dissy was worn out, the coil was burnt from a previous electrical repair, the balast resistor had snapped in half, and the solenoid only worked when it felt like it. Hence the re-wire and replacements... |
