Ok, so I think I mucked up a jump start looking at utube videos.
Had a few instances over a period were it seemed starting the car was a bit laboured. Did some some bits and bobs with doors and tail lift opens internal lights on for a few hours.Recently only done a few short journeys.
Anyway had a complete failure to start at the worst time as I needed to get my dog to the vet, no crank whatsoever. (Still need to get there but stuffed now until I have my car)
Suspecting battery and in haste I jump started with the wife's car, but I did it with the her engine running to What I suspected was a complete dead battery.
Great stuff mine sparked into life, sadly though with an error message to drive to the workshop without changing gear for the first time ever. I couldn't drive it for 15mins as I couldn't get it out of Park. But after a decent idle and a few turns off and on managed to get it into Drive.
Anyway my local Indy let me bring it down straight away after I explained the warning. (A big thanks to them) The battery is confirmed as caput, but until replaced won't be be sure if the error message which is related to the intelligent servo module is an actual fault or related to such a low battery condition.
Searching utube I did find an video when someone jump started there ml and afterward they needed the ISM replacing.
My question is really and the bumf above is to give context;
What is the correct procedure for jump starting, should I have done it when the other car was turned off and not up but not running? Reading comments about leaving the key out, should I have left out in my car, before I tuenwd on the wife's car.
I did check manual but it wasn't specific. Normally I'd take my time in doing such things, but was rushing to try and make an appointment time.
Cheers
