The earth bolt near the rear light unit was loose making a poor connection. You will need to remove some of the boot trim to get to it though. The earth point is just below the light unit slightly towards the centre of the car. Check both the rear earth points while you are in there. -- David C 156 Selespeed sp3 + Brembo conversion |

Unfortunately, it's not earthing. I should have checked my post more carefully. The rear off side tail light glows dimly when the side lights are switched off but comes on at full intensity when the side lights are turned on. I've got to find the bulb failure unit. -- Best regards Rick |

If there is a poor earth strange things can start happening. On mine the brake lights were permanently on! Even if they were off when I got out of the car, when the indicators flashed when the car was locked it set off a strange back-feeding via the brake lights which would then come on slowly (like turning a dimmer switch!) and stay on. -- David C 156 Selespeed sp3 + Brembo conversion |
Rick,
The bulb failure unit is actually in the rev counter itself. I have the wiring diagrams on CD. I could e-mail sections if you like.

I got the answer to that from my local garage - "Yes!" However they did say that it was easy to remove the rev counter - 3 screws. It comes apart easily too. The fault is a VND810 transistor which switches the lamp on and also does the failure detection. It's easily repaired, if you can find a component distributor with a less then 1000 piece minimum order quantity. -- Best regards Rick |
