Won't start! - Page 2

Yes, good call

The nice repair man checked the battery with a multimeter whilst the engine was running and explained that the reading could suggest what was wrong:

Less than 13.something volts means the alternator has gone (not enough charge getting into the battery).
Fluctuating between 13.something and 14.2v (I think), the alternator is ok but the battery is not holding the charge (as in my case).
Over 14.2v both ok.
He explained that the engine needed at least 14.2v to start, any less and nothing would happen.

I'm sure someone in the know will correct me if this is a load of bollocks but it might help someone with a similar problem!

He is not very clever then, as a car sat there will not have 14.2v in the battery. Either you misheard him or typo.
