Electronics is my business -- so that's good. I've seen some web
instructions on getting it out but just looking at it it seems awful
cramped in there (and the bolts are hard to see -- facing downwards?).
I'll get it out....any tips?
I'd buy a rebuilt one off Ebay but apparently I have an odd part
number that isn't stocked.
I have the T5.
Hi,
I've just finished repairing the module from my '96 850, and electronics is
also my business. Have a look at
http://www.matthewsvolvosite.com/chat/phpBB2/viewtopic.php?p=46827#46827 if
you already haven't.
Removing the module on my car (right hand drive non-turbo) took less than
15minutes. Access was good. I also had a set of Torx sockets. Removing
the 4 "one-way" spring clips on the module case was not too difficult, but
opening the case took me at least an hour. I was trying to not damage it.
I used a piece of flat spring steel about 2mm wide, bent at 90degrees to
scrape as much silicone as I could from the groove, then some brute force
and leverage.
Inside the PCB is coated with a thick silicone-like conformal coating. I
had to peel it off the socket pins to get a good look at them. The pins for
the two pin connector were obviously fractured (after the coating was
removed). I cleaned the coating from all of the connector pins desoldered
and then resoldered them, although I think only the two big ones needed it.
I used clear nail polish to reseal the PCB, and a neutral cure silicone
sealant (made by Selleys) to reseal the casing, used sparingly. Then after
the case was back together I ran a bead around the gap, and smeared with my
finger and wiped the excess with a rag dipped in mineral turpentine, to
neaten it up. I put it back on the car almost straight away, but left it
overnigh before starting. Although the tube says 72 hours to completely
cure, a big blob I had left over seemed "solid" overnight.
Unit has worked fine ever since (about 5 days so far).
regards
Barry
