Hi All, had a battery go bad, big hassle, but routine stuff. Nobody believes you anymore, they must recharge overnight and put is on their load tester because my $200 one is not approved by their company.
Not my surprise. I cleaned up a bit of powder, did a thin layer of grease, wiped it all down and cut out roofing felt the same size as the four places the battery sets on. Hope this will help keep things a little neater.
Now for the big reveal, behind the battery, mid car, right of the main battery hook ups are a vacuum hose going nowhere and a plug in connector going nowhere. The wire is white with a green strip which seems to be used in a few applications and is switch controlled.
I can only guess, but I didn't get some optional item or I did and it didn't work, so "they" through it away.
My question, do I plug the vacuum????

Thanks, just having a rant, WAYNE

 

The green and white wire was for a disable device used when the car was shipped accross the pond.---ignore it.

The hose is to vent the battery to the outside though a grommet in the floor of the trunk. That must be connected to the battery vent. If your replacement battery did not come with a vent adpater, you should get one from wherever you purchased it from. Should your battery ever overcharge due to a fault in the alternator, enough hydrogen gas can build up in the sealed trunk to possibly cause an explosion....that is why the vent is there.

 

WhiteXKR, That sounds like I need to get my a++ up and go take care of this right away.
Thanks very much, don't need myself and car giving a fire works display!!!

The Transit Relay is removed and discarded during the initial PDI at the dealership. The green and white wire is then tucked behind the trim and the main battery earth terminal connected.



The correct battery has a right angled outlet (arrowed in red) which connects to a vent pipe going out through the floor.



This is probably your 'vacuum hose and plug in connector'?
