Engine bay wiring fault most likely...
Is that common on the F11, or are you casting nasturtiums on the plod wiring?
Any installation of kit into a blue light vehicle has to conform to strict rules dictated by a cross Govt dept body. They are supposed to ensure that things are done properly with each installation "type" being logged for audit purposes. Many are fitted with a "run/stop" system which means the driver can jump out & leave it running but it can't be driven away by a passing opportunistic scumbag. These systems interface with the ignition system - but do so with manufacturers approval if correctly installed.
Do you believe in Father Christmas? Owners of ex-plod cars might beg to differ.
Things have changed dramatically in the last ten or so years. I know for a fact that when the last plod Omegas went into service that things were done locally on an ad-hoc basis by many forces/brigades/trusts, almost as an after-thought. The significant increase & complexity of installed kit in recent years has driven increased installation standards - which were poor. I oversaw an installation only a few years ago in over 700 ambulances - there have been zero defects. So it can be done properly.
Of course this could be a poor install - but it's no longer an automatic conclusion to jump to.
