Three faults, all traced and fixed for next to nothing

- Russ Brown

When my 90 developed three electrical faults in quick succession my instinct was to find a common cause. But common sense ruled there couldn’t be a common earth that fed only the front left courtesy light door switch and the right rear indicator, and which would also cause the oil pressure light to flicker.

Any thoughts of a common link were removed with a flick of the door switch bringing the light on – simply a rubbish switch!
