Re:Gen 4 Battery swap

Lambert, it can be done by the Suzuki Method, as above, then you re-program all the things that drop out. Or, you can do what the battery suppliers do and provide a back up.

However, there are different local solutions in different places. Some remove and bench charge once a month. I top-up with solar once a week. Others have a Lithium Battery under the passenger seat and a DC/DC Converter to keep the starting battery up. All this because someone in Brussels decided Australia can't use the hi-output Alternator cause it makes too much CO2 for Europe! The Alternator produces 80Amp max and 60A+ at 1050rpm! But little of that current makes it to the battery.

If you read the Forum Topic "Tonka's poorly", you can see just how mean the computer can be if it thinks you have had enough Amps for that drive!

The Battery bloke also said the new Ford Ranger is just the same as the new Suzukis!

I think the need for a supplementary feed is only if you want to keep any logged fault codes in the system, the manual mentions disconnecting the battery if you're not using the car for a while - unlikely they'd say that if you had to take it to the dealer to get everyting working again (I hope!)

All done!
Battery swapped, Car Serviced, new 0W-20 Oil.
Codes scanned, one Fault Code found, in hand with the Service Manager.
Today's Battery Resting Voltage is 12.73V, that is with just the Alternator re-changing the battery.
Now it just gets better!

My Joy was short lived, the Alternator was 'switched off' on the next drive! Suzuki sent the RAC Man on Saturday to switch the Alternator back on.

I am now looking for a lo-voltage alarm. I want to use in the 12V Accessory Socket to power it and set to 12.6Volts and to go off when the alternator is switched off. I can then stop and re-boot the car and the charging system and continue my drive.

Something simple please, a piezzo buzzer with a small switching circuit. I don't need any more computers or visual devices. I only have one eye and limited vision so an audible alarm is much better for me. I have asked on two Facebook Forums, no success. 40 years back I sold these things for boats and trucks.

thank you, George

How do you turn the alternator off and on?

Hey that's my question! I've PM'd the latest 'fix'. Four hours after shopping, the battery resting voltage is 12.73V! :woohoo:

Thank you for the help with the search, this one looks to be the goods! There is a video in the link.
