So in preparing to sort out all of the remaining niggles, a new one reared it's head last week.

The near side headlight and sidelight both wouldn't come on at all. A 30second drive seemed to jolt the dipped beam enough to shake it into action but the sidelight was still out.

Presuming that this is an earth fault somewhere, does anyone know which earth point it's likely to be.

The near side rear brake bulb also keeps blowing, so I'm hoping it might also be on a shared earth?

Having recently got married, and paid a hefty bill for a throttle/lambda problem to be resolved, I'm trying to avoid booking it in again as I know electrical issues can eat into the labour time!
Anyone had anything similar?

Dave - the earths for "the front" of the car are just in front of the dry sump tank...maybe toward the drivers side. Best seen by removing O/S/F wheel and looking at base of tank area. The earths are on a 15mm (?) stud on the chassis...you'll see all the black wires going to it.

The main starter/engine earth is on the O/S engine mount bolt - can do that at same time!

Can't help with brake light...maybe lamp holder is a bit corroded - drawing bigger current?
