ignition back feed - zx_volcane - 30-04-2012 Don't you just love electrical fault tracing? So this morning met with flat battery on the black 3 door zx Jumped it and turned the ignition off - engine still going Interesting pulled the stop solenoid plug and it cut out so not the solenoid ignition lights still on with key removed pulled shroud round ignition barrel and disconnected all plugs ignition still on so ruled out the barrel discounted feeds to starter and alternator, ignition still on - so not back feeding through these damn, only leaves the loom wiggled everything i could see, no joy cue lots of loom nonsense, tracing under wiper scuttle, under nearside arch, blah blah blah all looks ok, no shorting ..etc bit more hunting with the multimeter to see if an components are live, found the radiator was showing a about half a volt and found down the offisde side of the radiator the alarm feed cable was shorting itself out. nice > Re: ignition back feed - cully - 30-04-2012 good find! could easly been on fire when you went to it Re: ignition back feed - Joe - 30-04-2012 right, so that little short was causing it to carry on running? so in theory if you link those 2 wires you could bump it? Re: ignition back feed - zx_volcane - 01-05-2012 It was shorting against the radiator / chasis and putting 12v back through the earth and through the whole system. You can bump a diesel by just putting a live feed from the battery to the stop solenoid.
