Hi Bricuda - does the needle move quickly - if so its most likely the voltage regulator - but I would get the alternator output checked before digging underneath - faulty earths tend to give either erratic readings on the guage or no read at all. Remember its called a guage - not a meter. The purpose of a guage is to estimate or judge levels whereas meters are designed to give a measurement. Fuel guages on cars are notoriously inaccurate. It's as simple as this - the tank guage float goes up and down according to the amount of fuel in the tank and considering tanks are neither uniform in shape or profile at best it can only be an estimate. That's why most modern cars have a a warning light or buzzer.
