Normally alternator output goes straight to the battery, only the warning light is wired to the switch

Are you sure it isn't "dieseling" ?

Sounds like alternator is wired onto the switched side of the circuit - powering the ECU/coils. If this is the case the cure will be to wire the alternator feed via a fuse to unswitched side...

We had this when we first got out MS up and running.

The Charging light was keeping the ignition circuit energised with just enough to run the MS.. if you flashed the lights after you'd turend the ignition off that would stop the car.

We just put a Diode in the wire to the charging light, a nice cheep fix
