Starting problem

[keno]

When you say you cleaned the contacts, did you open up the solenoid and clean it internally. Common for the internal contacts to have green corrosion which intermittently stops the solenoid doing its job. Next time it happens short the big connections in the solenoid. If that turns the starter, change the solenoid. I don't know of anyone who had to strip a starter on the 600 to replace brushes. Heard of a few who had to because the starter was seized

I took out the electric connector block cleaned all contacts and soaked it in gt85, put back in done the same with the starter motor connection tapped the starter motor with the back of a screw driver and hit button,starts every time now.
