Discussions board for the classic MG MGA.
Ive started a new topic to so Davids wiring question is not lost.

This allowed for a mechanical rather than an electrical starter switch - cheaper, more reliable, but at the same time a little crude. The only way to make the key control it is through a relay or electric solenoid switch that is hefty enough to handle the starter amps.
The key is just on/off to the electrical system. The starter is hooked directly to the battery. Remember that MGAs came with a manual cranlk that you inserted through the front bumper in case the starter failed. So the electrical system would still work even if the starter were missing or disconnected :-)

It does seem to be a crude answer, it just is a little concerning when people play with the knobs when the car is parked....eg children between the ages of 2-21.
Oh, by the way has anybody actually used their crank handle to start the car in the last 50 years.

Yes, I have used the crank, had a loose battery connection and drained the batteries. It's surprisingly easy if someone helps by blipping the throttle.
