Starter motor knackered??

[dazza]

Have you tried arcing across the solenoid terminals with a screwdriver? I had a similar problem last year,  drove me mad,  replaced the solenoid, Still nothing on the button but would engage when arc'ed across the solenoid terminals. Think my starter was on the way out because eventually it made a terrible noise and bellowed out a load of smoke. Replaced the starter and still wouldn't start so I disconnected the meta alarm system and was back in business.
