Irish Mini Owners Club

for the last couple of mornings ive had to jump start my mini,she goes no probs then, the minute i switch her of her battery is dead again, it seems the battery isnt holding a charge, but can go for miles if i dont switch her of, any ideas

I had the very same problem myself last month. Even though the battery is only three years old, it needed a good recharge. Took a trip to halfords and laid out for a half decent battery charger, put the battery on charge (it took 21 hours on trickle charge) and it has been like a new battery ever since:-)
Before forking out, you might check the battery terminal clamps and alternator connector and belt tension but I'd say its just a tired battery in need of a good charge!

Give paul kelly a call in minifix on 087 2597085 he will point you in the right direction

I had the same problem with mine months back and it was the battery earth cable and it wasnt letting the battery charge so id cheack both your earths

winters are tough on batteries... more current needed to start engine, more lights, heaters and fan running...

check that your fan-belt is set to the correct tension so that the alternator charges the battery fully... the belt wears with time and it slips under load.

check the electrical connection on the battery, alternator and starter motor.. clean the battery terminals and smear vaseline on them when re-attaching.

when the engine is running, the voltage at the battery should be at or over 12.5 volts.
