Volvo 940 radio suppression relay. Replace or rewire?

They don't fatigue or get too hot those relays, unlike the fuel pump relayThey only ground the fuel injectors but if you need a spare I could get a new...

Also make sure the wiring bullet connectors are tight and secure, I've had to re-do mine before

BarelyRunning

A valuable source of information as usual. I thought maybe they had the same issue as the fuel pump relay. Inbox me with the price of a new one, definitely worth having a spare.

If reflowed with 2% silver solder, I've never seen them fail a second time

Yeah in my experience the issue is usually the connector rather than the relay itself.

Will have to investigate this. Fired up since reflowing the solder anyway.

A new relay will cost you $192 but will come from Sweden so unfortunately this could take 3-4 weeks

I think I'll try and find a used one, thank you though.

IPD has them for 75 USD.

Don't forget to add in the currency conversion and the shipping.

can order some other things to make the shipping worth while, or organise a group buy… I was just part of one and it cuts the shipping costs down by going in with a few others. skandix will also send small one off items with fed ex for 35 euros from my recent experience with them. Of course, if you’re happy to pay $200 oz dollars for a relay, have at it… just my 2 cents

BarelyRunning this maybe a long shot as this is from 2022 but I need to know what colour wires go-to what pin on this relay

You caught me at a good time.

Green/red to 87

Blue/yellow to 85

Red to 30

Black to 86

Narva part 68000, super common in other brands too. Fixes the problem permanently.

BarelyRunning thank you !! Worked out it works but the fuel pump relay is the issue
