Hello.

Mk2 2.8 V6 granada 1982.

Has been fine, started a few days ago and started fine, then starter motor engaged and stayed engaged whilst the engine was running, turned off and removed key and engine stopped then restarted a few seconds later with starter continually running (key fully removed). I have disconnected the battery to stop it. There are 2 wires connected to the positive terminal, a thick red one which I assume is for the spark and a thinner black one which seems to operate the lights etc... Including the starter motor. I have eliminated the ignition barrel by disconnecting the wiring; the the engine starts and runs normally once the thinner black wire is a disconnect from the battery.

Any ideas?

This is my first time on a forum so apologies if this in the wrong section.

Thanks in advance
Adam
