I’ve had a very wet day today, can’t get on with much else so cut out a mounting plate for myself incase I decide to get a Ctek D250SE for myself. A piece of sheet galvanised steel tidied up with some zinc spray.
Yes, zinc spray is it.
I use it all the time.
I am about to install my D250SE in a week. Can i ask what guage the negative wire is from the D250SE and did you connect it to the Aux battery negative post or the chassis? Also, did you utilise the smart alternator red wire to an ignition source?
I used 16mm² cable with an M8 ring connector at each end. Length in photo is 250mm (measured to cable ends) - you could go a lot shorter. It's connected to the M8 stud on the negative terminal of the auxiliary battery.
Curious, did you connect the Smart alternator cable on the D250? What of the 120 smart alternator cable?
I'm going to leave the smart alternator cables unattached for the time being, taking the lead from what Ineos have done with the Smartpass, at least until they come back with answers to the outstanding questions on this topic. I am minded to attach them if I get no sense.
Hi DCPU, I have my D250SE mechanically installed but after some advice regards the black wire from the D250SE. Did you connect it to the negative battery terminal?
No *, I understand this to be the linked to the charge voltage for various battery types; and as standard we have a wet battery, then it is correct to leave it unconnected:
Thank you so much DCPU if you had not replied I would have connected that black wire.
Have you checked your battery type?
Mine is an "EFB" also.
They are all EFB
Yes, until they aren't ~ exhibit A being they were all retail Smartpass until they weren't.
Not yet.
See @Jean Mercier's post with regard to what is now being fitted to vehicles arriving at agents (I'd link the post in but can't seem to locate it!)
CTEK seem very positive in comments to several owners, myself included, that it's OK to attach the red wires. I'm also trying to recall who posted some comments on the functionality that made a lot of sense...Given the fact the 120 red cable does not connect to anything, the comment is understandable. However I have asked Ctek if the wire can be connected and why not if the alternator is a modern smart one (unless Ineos have removed that functionality, but would think it’s tied into the bmw end of things. I am not a sparks, but now have 2 dangly red cables looking for a home and hate loose ends…..
