how to test instrument cluster?

[lasher78]

here is my instrument cluster on my 66 stepper looks pretty good so i would like to ask how you can test to see if all the gauges work right as the truxk does not run and engine will have to be rewired as mice have eaten thru alot of the wires...and the gen light gauge will it work with reglar alternator or does something have to be changed? would like to keep rhis cluster if it works but if not will make my own with new guages... any info will help and pics of anything that needs to be done. thanks in advance.
