So got the car back on the road today after having the earth done, mechanic left the battery flat so I bumped it, started ok so I drove about ten miles and left it running for an hour. All good.

Now, turned it off, tested to start again and it didn't ... Starter won't turn...!!!! Like its locked in place.... Will bump fine!!

Grrrr!!!!!

You sure its not still the battery ?

Have you tried jump leads to fire it up? As above sounds like a dead battery to me.

+3 for the battery.

The black wire that runs from alternator to battery went on mine, fried a fuse on top of the battery and also killed the battery dead.

The +3's are correct, new Battery in and all is fine

Problems all good now and I'm happy!
