A68B Microswitch, roof shell 2 closed, left - Updated!

[True-Blue]

I really hate to post this video, here it is...

Nice video, but his wire repair was ass.

Yes I’d watched that a couple of times already. Does he simply bridge the ‘signal’ wire for the good switch and the one throwing the error code?
Watched it a couple of times and want to be 100% certain

I see a useful wiring diagram has been added to another new thread…. Right hand side starting to fail more frequently now then.

 

[javis20]

He was shorting the brown wires. Pin 7 and pin 10.

 

[True-Blue]

I just want to say a big thank you to everyone who’s helped here. I managed to bridge the required pins and no surprise really, the roof completed its closing cycle and the windows have closed.

I’m drained, for other reasons, and I don’t know if I’ve got the energy to sort the wiring myself or just take it somewhere now it’s drivable again.

If I close the boot and don’t try and operate the roof will the windows operate as normal if I remove the cable bridging pins 7 and 10 can anyone confirm?

 

[True-Blue]

Just to add, I’ve removed the jump wire, closed the boot and…. The windows work and the boot still opens and closes.

Going to take a breather, have a little jaunt out in the Alpina in the morning for a breakfast meet… then consider what to do next

Quick update as now resolved.

As I suspected from the symptoms, broken wires in loom which it seems is nearly always the case.

However, the Indy was physically unable to identify where the break in the loom was, so replaced the whole thing.

I had looked at the wiring myself, before deciding to get an expert involved, and I couldn’t see any physical breaks either… not even a hint of a problem.

Now working beautifully again, and good to know the car now has new looms on both sides.

Happy days

Are you going to take the old loom apart to find where the break(s) are? :tumbleweed:

For what purpose?

It will be an internal break that was causing the circuit to break and complete… I could see the effect and all the sensors tested appropriately.

I could carefully remove the insulation and find it, but why?

 

[Reamesy]

It might help others in the future if it’s a common failure point. It usually occurs where the wires are moved during operation.

So others can quickly check these locations before replacing the lot.

 

[True-Blue]

Ok. I get that, but having seen the wire removed, and having seen most of it in place before it was removed there are no clearly ‘visible’ breaks.

I’d literally have to strip all the insulation (plastic coating) off of both wires to find the internal break… and then work backwards to work out where that was with the wires in place.

I’d like to think I’ve contributed positively to the forum over the years, but I don’t have the time or patience to do that on this occasion

EDIT - probably worth adding that after testing the microswitches, they ran a wire directly from the microswitch to the CTM and hey-presto.

For anyone sorting this themselves, the above point is probably the most useful test you can do once you have this fault code

 

[Reamesy]

Totally get that and your last point is probably the most helpful to others having similar issues. Thank you for your contributions. Time is precious

Didn’t realise it was so difficult and time consuming to undertaken…I’ll not ask again..

I have replaced both pairs on the right.
Just waiting now for the left to break at some point.
Think one lazy day i preempt and just replace.
