Recently, our tail lights, number-plate light, side-lights & dashboard would not illuminate.
That situation triggered a search in these forums; the threads I found relevant are listed below for reference.
I checked fuses (no 10 under dash & no 8 under bonnet), which were both fine.
I then started to look for & identify the relays.
A helpful post from MikeWalsall in the Lights???? thread described & illustrated the sequence and location of several relays.
First issue
There should have been 4 x H270 relays there, but the 2nd from left was actually a Volvo 9441160 (multi-use) 5 pin relay, with the connectors in a different formation.
Second issue
I found our relays are not in the same sequence (Tail, side etc are first & headlights are second).
By listening to (and feeling for) the relay click for headlights = ON, I established that the Volvo relay was the headlight one.
By disconnecting the other relays individually & trying the air-con and then the fog-lights, I confirmed the air-con & fog-light relays were in the expected sequence & were working.
So, this left the faulty tail, number, side & dashboard lights relay. I put the fog-light relay there for now, and will order a new replacement one - hopefully with some guidance ...
Where I need assistance is with
- I've seen lots of H270 relays for sale, but they seem to have different codes and different prices. Is there a specific one for the Bongo's tail, number-plate, side & dash lights, please?
- The headlight connectors on the Volvo relay; these aren't in a block like they are on the H270 relays, they are in a pattern as shown below - with only 4 of the 5 terminals connected. I've tried to make sense of the image printed on the relay, but I can't fathom it. I want to change it to also be a H270 relay, but I need help in understanding which connector should go where. There are wires connected to terminals 1,2,3 & 5 (no 4 in centre is not connected). Can someone guide me on which pin goes where onto the H270 ?
The 4th & 5th image are the connector pin-outs on the Volvo and H270 relays respectively.
Many thanks for any assistance / guidance offered.
