1.6L Ford Focus estate, made in 2000. It is right hand drive, although I doubt that matters.
When the ignition key is turned from "On" to "Start", there is a click (sounds like a relay behind the glovebox) and all power goes in the car. The battery is fine as the lights work perfectly up until the point of turning the key to "Start".
After some time (minutes) power returns to the car and I can attempt to start again. All power goes, as the radio is reset to factory and the clock is reset to midnight.
The MIL / Check Engine light is on, however my bluetooth scanner with various apps on my phone cannot read a code from the ECU.
Is the starter bad, or is there something else it could be, such as grounding?
