What is the question again? This images very clearly specifies how the switches are mapped to the various power points. Yes the roof has 4 power locations but three of them are controlled by a single switch, Ext 2, and the fourth (right front) is switched separately by Ext 3. If you are thinking each roof power point has a separate switch that is not how the Grenadier is wired.
Thanks for you reply. I clearly stated my question twice. It was not complex. From the picture you are referring to, I thought the owner collectively bundled three wires to be controlled by one switch. Why would three plugs be wired to one switch from the factory? Makes no sense, since there are four external labeled switches on the ceiling panel and four plugs on the roof. This is crazy. How would anyone know that? Frankly, it's a stupid idea!
The three power points are indeed bundled to a single switch from the factory. I agree it is an odd configuration. One of several strange choices by Ineos regarding the electrical system. Most owners question how the dual battery system is structured as well with everything powered by the starting battery and the second battery only serving as a backup.
OK, so which top power plug is connected to the single switch and which switch controls the other three? Is it as shown in the user labeled photo?I don't find the roof switch/power outlet configuration strange at all. One switch controls a single forward roof plug intended for roof-mounted off-highway lighting controlled from the driver's seat (or front seat in general). The other three roof outlets are intended to be used once parked up at the end of the day. A single switch sends power to whatever you have installed at the rear and (for RHD vehicles) on the off side. One click turns them on as you exit the driver's seat then you control each appliance individually through their dedicated on/off controls. I wouldn't want to have to return to the driver's seat to control my camp lights at the end of the day. On top of that the roof outlets aren't intended to be used for tactical purposes. If you need a different configuration start cutting.
The right front roof power point is controlled by switch Ext 2. The other three roof power points are all controlled by switch Ext 3, just as is shown in the image posted by Michell300. Horses for courses as to whether this works for any particular owner. Using Ext 2 to switch a front light bar is intuitive. Some people might like having the single switch Ext 3 control camp lights for both sides and the rear of the vehicle. Others might have preferred more control. Say one switch for a front light bar, one switch for camp side lights and a third switch to power a roof top tent. Of course the factory configuration can modified by the owner to better meet their needs. Personally I am likely to install an aftermarket switching system from sPod or Switch Pros in the blank section of the overhead panel which will add a much more flexible switching setup.
Yes, I have two sPods controlling the Bantam control unit on my Sprinter. Fully flexible and dimmable. Probable too much of a task to re-wire the Grenny overhead to my liking. How would you modify it? How to find where the wires from the four plugs join? If it were to be under the ceiling panel, then it's doable, but there's probably one wire going to the roof innards and then goes from plug to plug. Even installing an sPod requires a re-wire.
I don't plan to change the factory switch setup. It will be used to power some items but left as designed by Ineos. The sPod will be added as a separate system. The switch pad will simply be surface mounted to the blank section of the factory overhead panel (see image). The wire from the sPod panel will be routed behind the overhead panel, down the A-pillar and back to the electrical box under the rear seat to where the sPod Bantam will be attached to the 2nd battery. I will also be replacing the Ctek unit with a DC/DC dual battery system from Redarc.
That is the best way to do it since, I believe some have been found to be connected differently inside the overhead panel
I had indeed inverted connectors in the overhead panel. I diagnosed the problem thanks to a picture of the dismounted panel of another early user (perhaps @bemax ), but my dealer solved the problem.
Hi @Jeffrey
The image I posted above I took and annotated. The diagram was supplied to me by a forum member, who has asked me to keep their identity confidential.
Well, that was unresolved last time that you and @DCPU disagreed over originality and attribution of this same image.
I'm interested in that. If anyone knows them, please direct them to me. Cheers.
That is not the image I posted above in this thread. Yes that image is in the other thread I linked. However, any image than any member posts can be used by other forum members - it is part of the Forum Rules and this has been confirmed to me by Admins. Stop trying to create controversy, when all I did was try and help a member in this thread using my own image and a diagram that I was sent by another member and they were happy for me to use.
Appreciate your attempts to assist other members. Not aware of past politics and not looking to go there.
So attribution is important if you claim an image is yours, or you wouldn't bother correcting me at post 232, but you're happy to lean on the forum rules to use an image contributed by someone else? Attribution is about acknowledgement of the work done by others which makes this forum such a valuable resource.
