Blinking blinking warning lights

[chrisevans]

I hope you guys can suggest something - both the oil and temp lights are doing there own thing(flashing constantly) . I have had the oil pressure checked out using a gauge and its within tolerance for both tickover and 2000 plus rpm.

The water light is also on indicating low level , despite having changed the expansion tank sensor and obviously having enough liquid in it

I 'suspect' an earth,wiring or dash problem as both are on at the same time. Any suggestions as to where I might save some time.

I have seen a repair on the clocks to do with the water light which involve replacing a capacitor?

Its a 2.1 DJ with rev counter dash in an 87 Westy.

Pull the relay which triggers the coolant level warning (42/43?), if the coolant warning light still flashes suspect a dash problem. Do the panel illumination lights work correctly and stay on when headlights on main beam? If not dash earth is suspect, I would be suspicious of the 14way dash connector.
