volvo 960 91/92

[solder]

Hello to all,well i'll be honest joined forum to try and get hold of(and please dont laugh) a 960 2.9 auto estate year 1991/1992 speedometer or the complete cluster. My car has only done 80 odd thousand miles and is our only (well was) runner at the moment.I have replaced virtually everything on the car with new and cleaned up all electrical contacts,waxoyled and mechanicals blah blah and is meant to be a keeper .If i cant find a speedo the car is destined for scrap and to be replaced with a chrysler 300c(wifes idea, shes sick of time i've spent on the volvo).So with that are there any speedos about so i dont have to scrap my beloved volvo.PS the speedo is beyond the capacitor repair stage.

Solder, its not that simple. Whats wrong with the speedo? You need to establish if its a VDO or Yazaki instrument and the Electrical Instruments FAQ on Volvo Maintenance FAQ for Volvo 700 900 S90 V90 Series Cars will help you. There are 3 or 4 different types of speedo used on the 960 between 1990-1995 and you need to check the securing and connections (very carefully) on the back before buying. Generally, remaking the connections, both soldered and very important, the screws holding the gauges to the frame as the latter make the connections to the circuits, may resolve your problem. I have been looking for a replacement Yazaki speedo for my 1993 960 for about a year now....so good luck. I have two spare consoles, both of which were no good for my application. If you can get a photo of the back of yours I might be able to help.
Cheers.

Thanks for reply its a 92 yazaki and im quite familiar with these speedos its not just the capacitors that have blown the corrosive innards have also eaten through some transistor legs and several of the pin terminals on one side of chip.Its the earlier speedo with the 4 brass raised screw contact terminals, twin male spade connector and 4 plastic mounting bosses(not the 6 pin female ribbon connector type).Alas my spare backup 25000 mile unit was lost during a house move.So unless anyone is prepared to repair it or a good replacement becomes available then by the sounds of it thats it............MJK164 it just so happens i have a spare 93 960 6 pin ribbon speedo that was working prior to scrapping our previous 93 volvo 960 lol.poor pic enclosed and no! the needle stop pins are not damaged there was a nice comfy sock under each speedo

Here are some pics of a full cluster that I have here. The circuit sheet indicates that it is a YAZAKI. The down side is that it would appear to be from a 1995 model. Have a look at the pics and if it seems suitable drop me a PM. In the event of multiple interests, solder has first refusal.

Apologies for the picture quality - they are taken with my old style phone. If they are edited any larger they do get a bit grainy.

I can put you in touch with a person who is in the process of scrapping a late 1991 'H' 745 (Oops! meant a 760) 230FT that has a similar Yazaki fitted ... if that helps anyone. PM me if you want. Bob.

Cheers for the offer migrator but its the wrong one could just about make out the pics when enlarged by one pixel lol(no offence)nearly as bad as my photo.Bob i must admit i dont know about the 760 speedo so any helpful contributions from anyone as regards that interchange im all ears.In the mean time ive just found some time to search through a friends electronics bin for any spare components beyond capacitors.

[bob12]

As very late 760's and early 960's of this time were in the cross-over period between the 700/900 range, I have a funny feeling that you may well find the Yazaki clusters (and guages therein), together with fitted looms etc, are one and the same animal, but of course as usual, the proof is in the physical examination or detailed photos, unless you have the Volvo Pt No. Bob.

Lol,well out of desperation and allocating more time on it, i managed to get most of the replacement components and now bypassing the heavily oxidised and disintegrated pcb traces with wires and straining my eyes and mind.Just waiting for a couple of resistors at moment then see if the surgery has been in vain lol nothing ventured nothing gained.

[solder]

Sorry for blurred photos.The two original knackered resistors(the leads on one side of both had been eaten away)were 3 band 20% tolerance the one furthest from camera WAS orange,orange and red and the closest was brown, blue and yellow now replaced with (in previous same order)brown,blue,black, black and brown 160 resistance............orange,orange,black,black and brown 330 resistance.Blue wire bypassing eaten away trace.The large blob soldering is due to bridging disintegrated trace at mounting holes and there is still a capacitor to replace behind the resistors.The reverse side is spaghetti junction and the out of shot far left disintegrated chip pins have been rebuilt lol.The next post will be if it worked or created a smoke effect dash,not hopeful but oh well.Ps the capacitor that was behind the big black transistor was the main culprit for dumping its corrosive innards.The pcb doesnt look that bad after cleaning but with a 40mag lens wellllllllllllllllll.

Pic just for reference might be useful for someone.Top 1992 volvo 960 2.9 auto estate and bottom same car but 1993.The red circled area would normally have the twin male spade connectors sticking through that are affixed to the 92 speedo(speedo was not in casing when photo taken).And bottom speedo shows the 6 pin male ribbon connector that goes to female connector on 93 speedo body.Should also have added to original first post the auto gearbox relies on the correct signal from the speedo to work properly on this car and usually gives 232 code SPEEDOMETER SIGNAL MISSING on this obd1.
