144 dl auto wont start

[scooters]

Hello all. After selling my orange 144 to a mate of torstens I bought her back last week. Today I drove 200 miles trouble free except fot the left turn indicator giving up the ghost and an old and obsolete exhaust clamp rattling along the m25 for 10 miles before disintegrating and giving the 60k merc following me a fright.
Anyway I pull up at home turn the engine off then decide to restart it to move the car and nothing not a sausage

There is charge the brake lights ampights all come on all the componentds work and all the ancilliaries work as well but the starter won't crank. No whirring noises or ominous clicks just nothing.

I have taken the dash to bits and checked connectionsm I suspect a loose earth or connection. I don't know these cars but they are pretty simle any ideas?
