Battery Change

Just did this on my 550. Threw the kill switch. Disconnected the battery and swapped in the new one. Reconnected, and turned the kill switch back on. Started car and let idle for about 10 minutes or more so the computers could "relearn." All is fine.

fc- See if this helps after you reconnect. This should be done every time the battery is disconnected to let the ECUs relearn and zero out extraneous codes.

Is there a similar procedure for a 550?

I regularly turn off the switch when leaving the car for several days and usually just let it idle for 10 minutes after reconnection.

 

JAB- Not that I have seen. My 550 tech data is limited to owner's and workshop manuals, plus a parts catalog courtesy of Ricambi. I have very few 550 tech bulletins.

The 550 WSM only mentions the idling speed adjuster reset procedure following battery reconnection. This is where the "10 Minute Rule" comes from, I suspect.

fc- Some guy named Ferrari, not Enzo, but Piero, I guess. First time I looked in my engine compartment with a Corvette mechanic friend of mine, he said "Have to move that reservoir to get that out." Pros think that way, us amateurs want to move as little as possible because it is just one more thing we can get wrong.

The latest MTP-6 comes without a carrying handle

You have to move the reservoir, but that's all. Its not necessary to drain it, just leave the hoses connected and move it out of the way.

 

You must be kidding. That is one of the easier batteries to replace. On the Benz you have to take the interior apart. On a 348 or 355 you jack up the car remove a wheel and the inner fender panel. Now you can see it. A Citroen SM requires removal of the right front fender. I am really sorry if you think 3 6mm nuts is a bump in the road. Have a good look at the car, a really good look and package it better. They did a damn good job. its easier to work on than my Ford.

 

I agree.I just put in an Optima in my 550. After I got the job done, someone suggested that the Optima is a poor application for the 550. It is tall and had very little room up top, and I had to install a longer bolt in the bottom holdown, but a fairly straightforward swap.

I turn off the batter switch to the remaining electronics after every drive....to preserve battery charge. I seem to have enough stray voltage requirements that I will find a flat battery in 14 days if I have not driven it in that period. Any reason to have concerns with what I have posted here? Well, other than I can go 14 days with out driving her.

 

Brian- Proves my point perfectly.

Axecent- On my 575M with an Interstate, the car can be left three weeks with everything connected and there is no difference in starting it compared to startign after one day. Do not do that as a matter of course, but forgot it once before a fishing trip. You should probably get a battery tender.

The Schumacher SE-1-12S Battery Charger and Maintainer can be mounted conveniently in front of the coolant reservoir. (In this case, both the reservoir and charger have to be tilted out of the way to change the battery )

Alterternatively you can just attach the pigtail connector to the shield, you have to plug something in anyway, it might as well be the lead from the Battery Tender instead of an extension cord.
