How to replace battery - help please
My car wasn't starting up as easily as usual and the fuel gauge needle was dropping when attempting to start. My 2.2 EX currently has some RAC battery in it so I decided to order a Bosch S5 to replace it.
Despite being pleased with myself for being so organised, the day after placing my order the car wouldn't start! Assuming it's nothing more serious than a flat battery, it's a few years old and it has an inspection feature, and the green ball is sat at the bottom of the chamber.
What I'd like some help with is the correct procedure for changing the battery. Strangely, the car's manual doesn't have a section for this and there's nothing in the Wiki.
Reading some of the threads on here there's mention of leaving an hour before reconnecting and having the car locked throughout, but could anyone point me in the direction of a step guide for the end-to-end process please?
I know it's a straightforward job, but I'm most worried about messing up the ECU or setting the alarm off.
Thanks in advance.
