1971 E. Rear brake light repair (is this wise?)
Hi all,
The rear nearside light seems not to be working. The brake and indicators are fine. Looking at Warren Townsend's wiring diagram (Thank You!), The two rear lights (side lights?) are fused separately via 11 and 12. Would it court disaster, to splice the lights together, using the working side's supply? I checked the wire to the non working side, it is only supplying about 0.4V...which I assume is near as dead. The other side is a healthy 12+V. This is a short term repair of maybe 3 months. Regards |

EDIT: unless your car came from N.America you likely don’t have “side lights” as shown on the diagram and the pic below. So your problem is with the “rear light” as it’s described on the diagram ? |

The RHS front and side and tail lights work. The LHS front and tails do not. This is what led me to the fuse. I haven't even checked the fuse. The vehicle was taken in previously to get the rear tail working. It doesn't now...and I don't quite know how to diagnose! |

It is a UK car and yes, you are correct. It is the rear light and the front..light that carries a "side light with indicator" ? Thank you for correcting this, as they say, the quality of a question is entirely dependent on the clarity of the question!! |
Still waiting for the fuse check but would also say to confirm a good earth to complete the circuit. When the earths are made via screws into the bodywork metal they can fail due to rust. Not unusual on old Volvos.

I'm a firm believer in letting fuses do the job they were designed to do, so I would not splice the output of fuse #11 and #12 together.
Fuses #11 and #12 are the same rating. What happens if you swap the output wires ? Does the problem change sides ? Do you have a Volt Ohm meter (VOM)? If so, you should have 12V input side of both fuses. How about the output side ? At the connector where the wire to the lights slips on ? I had problems with the connections in the fuse block being internally corroded (between the riveted together parts), causing all kinds of intermittent problems with the lights on a 220. |

1971 1800E wiring diagram. Note that the number plate lights look to run via the #11 fuse so if they are working check #12.

Ok,
This is embarrassing. The fuse was blown and I poo'd myself and thought that the Norse God's had it I'm for me again. Thank you all for patiently assisting...again!! U |
