Testing gauges in the junk yard

[thistle3585]

There are about a dozen Jeeps at my local junkyard. I need a new clock, tachometer, volt meter and oil pressure gauge. What is a quick and easy way to test them to see if they are functional? They are installed but there isn't any power running to any of them.

If your buget allows you, i would get new guages. By the time you spend your time and effort trying to test them and remove them, you could replace with new ones. Remember these junkyard guages have already lots of hours of use, and accuracy may be off. Just my 2 cents, in the end its your choice.

Good luck!!
