Gauge earthing issues with the RV8
Paul Atkinson experienced a puzzling issue when driving his
RV8. When he switched on the dipped headlights the needle on the temperature
gauge climbed and went off the scale! In a post on the V8 Bulletin
Board he sought fellow members' views on how to solve the problem.
Julian Drew responded saying "you may well be correct
with an earthing issue. As a quick first easy check, have a look at
earth point 3 and earth point 4. Both are located under the bonnet
where they are exterior parts and prone to corrosion. Both points
earth the head lamps left and right".
