Install a new Battery

[Tyson64]

Hey Everyone, I just need some help with a new battery installation. Is it a straight forward disconnect Positive + then the Negative - or is it a put a connection on the Alternator Positive + and a Negative - Earth to keep the Electronics all up to date, as in there is a small backup battery for the Electronics... Cheers

If you disconnect your battery you will loose all your cars memory like radio station and phone numbers in the MMCS.

If this does not bother you like most:
1. remove 2 battery clamps. This requires 10mm spanner. Once they are loose the hooks pull out.
2.Remove earth connector
3. remove the positive connector
4 remove battery. be careful as it may have acid on it . Wear gloves if you are worried.
5. fit new battery in.
6. connect positive battery connector
7 connect negative connector
8. connect battery clamps
9 spray connectors with a moisture guard spray
10. wash hands and any clothing that touched the battery.

I forgot to add if you want to keep all your memories then you need to do all the above with having jumper leads connected to a 12v battery source and the terminals. You can do this but you just have to make sure they dont slip off. I did this and connected them to the new battery. The hard part is slipping the terminals back on with the leads on the battery. It is best to use a third battery if you have one available.

Apparently you can buy a 9V battery tether off eBay which plugs into your ciggarette lighter socket and it will ensure your memory settings are kept. I have no concept of how this works but I've seen it at my local auto electrician.

Great thanks for that, I did do a search and checked every page of 'Maintenance' and 'How To's & DIY' but either missed it or I looked in the wrong section as usual, dopey me... Thanks again
