guages.

[nipper]

I am trying to sell my 1985 Formula F-2 sunsport cuddy. The only guages which are working are the voltmeter and the tachometer. None of the other guages appears to have any power because the panel lights do not light up on the non-functioning guages, but the lights come on for the voltmeter and tach. I am not very good at electrical work. Any suggestions on where I should start first?
