Thanks that is just what I wanted to know.

At Least it gives me some thing to check to see that i am not being taken for a ride!

Motor 7 is frozen effectively on my top although its refusal to move could be caused by others not in sync. Bloody annoying that it just decided not to work one day without warning. it's not like it has been abused or stopped mid flow i have been careful with it at all times.

I have found the manual closing procedure but the i could not find the detail in the manual on the manual opening procedure.

Thank you so much that was a really big help in assisting me to understand what is going on. i have been really worried about it and the potential size of the bill.

@Ulrich @DJS @Unhingd

Fault code B1442-13

The tech has stated he can't get the roof open to change the latch motor and he needs to do a full interior strip!!!!

I am sure this is wrong and the bulkhead will still block access to the the primary drive motor on the left hand side?

Help please guys.

This is above my paygrade.

 

lol no worries mate please keep me in mind if you chatting to peps that may be able to help.

thanks

Hi John ,

B1442-13 = Front latch motor circuit open
so your problem seems to be the unlatch mechanism motor.
This mechanism can easily be unlocked manually with the tool
stored in the passenger footwell. When released the tech should
be able to open the roof with the electrical motors to get access
to the top headliner and the front latch motor.
To replace one of the primary drive motors the folding top has to
be removed from the car which needs prior disassembly of some
interior parts .

Ulrich

 

 

That's what I expect when using Jaguar's SDD .

Did you already check the connectors to the drive motor ?
I don't know whether they are accessible easily but I remember
that those "smarttop"-moduls loop into the wire harness at
that position and no user ever complained about a difficult
setup. So worth to make an attempt .

Ulrich

 

Realy that is interesting the dealer is telling me that they can not get the roof down without a strip.

Problem is the connector is an easy reach through the flap when the roof is down! with the bloody thing stuck up it's impossible (I did try to get to it to give it a wiggle)

Honestly I am not impressed with a fail close design that requires a day of strip to get to the motors! no other convertible i can name has no manual open operation as far as i am awear.

I see ss23 had a similar issue a few years ago, but didn't post what the resolution was. Might try PM'ing him too.

My motor was replaced by the dealer and I've not had an issue since. Coincidentally, I will be dropping my car off for servicing tomorrow and will check with my advisor regarding your issue.

I've got a good relationship with him so I'm sure he'll tell me as much as he can (and be honest). My guess is that your dealer is trying to exploit you now that you're out of warranty. Not sure how it works in the UK, can you find an alternate dealer or perhaps another workshop? I'm sure you'll have plenty of Jaguar experts in the vicinity.

 

Thank you I am finding it very difficult to believe there is no way of getting the roof down to get to the motors without resorting to stripping the interior out wholesale. (estimated at 8 hrs work out and back in)

That coupled with the possibility that the motor may be ok and it may be something else entirely!

Does not fill me with confidence with the bill lurching towards £2000+ GBP ($3000 us) a complete new top is around the £5k mark!

Any and all feedback is very welcome as it will help me tackle the Dealer and the cost.

Regards

John

 

 

There was a TSB for early convertibles to move one of the roof harnesses, but I believe this was to avoid wearing the fabric, rather than damaging the harness (loom).

 

 

@Ulrich

Do you have any detail on how to get the roof down if it is stuck (primary motor wont move) but is allegedly ok?

So far they have stripped the interior
and are now taking to roof apart!

 

As stated earlier, the problem is likely to be a battery issue - low voltage can cause a variety of apparent problems (meaning that the real cause of the problem is not in the component, but in the power source). And new batteries are rarely fully charged...

 

Hi John,
due to the outer shape of the drive units the motors must
have a worm gear drive to the output side. It depends on the
design of those worm gear drives whether they are self-locking when driven
from the output side or not. Since the roof can be closed manually
I assume that they weren't self-locking therefore closing the roof
should basically be possible. To move the motors backwards (which is always
difficult with a worm gear drive with high gear ratio) I think its
extremly important where you try to push them back . As you can see in the
picture the motor drives the primary linkage by a gear drive rotating around
the main bearing (label #4) . The rest of the roof mechanism can be considered
a multi bar linkage driven by the primary linkage . For example if you try to move
back the top by pulling on part #13 a dead center positon of the "multibar linkage"
might prevent you to move the mechanism respectivly the motor, however if you try
to push on the primary linkage ( arrow drawn ) it might be possible to move it back
because you directly create torque around the main bearing.
The workshop manual gives a warning that opening the roof manually
might cause damage (note:if you push at the wrong position) to the mechanism
but it didn't say it isn't possible. Unfortunatly all information given in the
workshop manual isn't detailed enough to fully understand this complex mechanism,
that's why all this is just pure theory.
I don't have any practical experience working on this folding top so unfortunatly I
only can give you some thoughts but no proved procedures to get this problem solved.
Regards
Ulrich

 

John,
I hadn't bothered to look in OzXFR's posted repair manual, since he has a coupe. But there's a large section on the folding top in it. no idea if it's helpful or not, but check out section 501-18B.
