Hi there guys, i have posted this in another thread but realised now you have a dedicated place for electrical.
My guage when i am driving reads at 18 volts, so i bought a multi meter and tested it thinking that perhaps it was a faulty reading. but NO.. it is actually reading at 17.63 volts. What could be causing this and how should i go about fixing this?

Cheers Barney Rubble.
