btw, the reason the relay under the hood that powers the injectors (and on some cars, the ignition coil), is called the "radio suppression relay" is as follows...

on 240's, the main fuel injection/pump relay was over behind the glovebox, the fuel injection half of this relay powered the whole FI system, including the injectors. on the early 740, they consolidated all the relays in the central panel (on 240s, they were shotgunned all over the place). When they moved the fuel injection relay directly under the radio .... the high current pulses that power the fuel injectors made static, especially over the AM band.

so, they added a relay under the hood to move the fuel injector power away from the radio, hence the name, 'radio suppression' ...

 

Interesting.. and somewhat of a trap for new players. I couldn't help wondering what radio suppression had to do with fuelling when you first used the term.

 

Are you still without a start? After all this time?

 

Yes lev. I have just ordered the relay and new radiator reservoir from Pelican Parts. They will be with a friend in LA awaiting trans-shipping along with some other American goodies. Avery Dennison stone chip film, boot stretcher hopefully for unwearable Eyetalian m/cycle boots, Dremel maybe, pex pipe crimper hopefully. As the TV ad here for Mainland Cheese goes, "Good things take time you know."

 

OK, so long term project then... I'd have loved to swap you some relays for that cheese!

 

I have given up on the extras. Infernal girl at the footwear place a total **** and completely curbed my enthusiasm for American shopping sprees. Happy to do a relay for cheese deal any time.. but I think I might be on the winning end of that one. On the other hand you might too.. we don't dose our cows with recombinant bovine growth hormone :-) http://www.mainland.co.nz/

 

Pierce I have finally summoned up courage to look at this. What I see above my ashtray is a little felt floored partition to the left hand side of which is housed the cigar lighter. I can't see that anything unsnaps but on either side of the partition seems to be a solitary screw. Are these the Phillips srcews to which you refer?

 

the square bezel around the lighter itself should unsnap and expose a screw.

 

pierce thanks for this. I have attached a photo. I take it the little "square" bezel is the one I have indicated. When you say unsnap should I coax it forward or put a knife beside it to prise it out?

 

yeah. stick your finger in the lighter hole, there's a gap between the plastic bezel and the metal socket, grab it, wiggle it a little, the bezel should pop right out.

 

Just pull that little "lighter" plate straight out, be brave--it just unsnaps. There should be two Phillips screws behind it. Take them out and this will release the left side of the utility tray/lighter base. The right side has a couple of small tabs that hold the tray attached to the side, so the left side has to come out first. Unplug the wires to the lighter and the courtesy mini bulb which is probably burned out, and take out the whole assembly. The Relay Tray will then be accessible.

 

Thanks pierce.. I'll give it a go.

 

Just a note to say thanks to all and pierce especially. My new relay eventually arrived and the installation was a snap. Indeed I am cautiously hopeful I have diagnosed the problem correctly. The old relay had burned contacts and so far there have been no more problems.. wipes brow.

I may have to start another thread on this but while the parts were removed awaiting reassembly my cigarette lighter went walkabout. In case I go secondhand for a replacement can anyone tell me what other Volvos share this part? In case I go new does it have a part number? My searches have drawn a blank. With thanks again.

 

JUST the lighter, not its socket? you could use the lighter out of most any car, but another Volvo lighter from anywhere +/- 5 years of yours will have the right look and feel.

 

Hey pierce.. I somehow thought you might have a little wisdom on the subject. Yes it is just the lighter. I have noticed some generic ones on ebay which explains your "any car or Volvo +/- 5 years" comment. I will hold out for OEM.. probably new being that my philosophy is always to go one better never worse.. that is a slippy slope I prefer to avoid. Many thanks for your help.

 

well, according to my parts catalog, a 1994 940T lighter has two pieces, '****' 1258269 and 'glow filament' 662108. at www.volvopartswebstore, the glow thing is $14 (and fits 93-97 850s' as well as 92+ 960s), and the **** *was* $3.42 but is NLA (no longer available... this **** seems to be any 940 or early 960 specific)...

so, I suggest you scrounge a lighter from from any 940, its exactly the same as what you lost.
