I'm rewiring the electrical system on my Allis-Chalmers FP40 fork lift, and while I've got everything torn apart I thought I'd also replace the gauges on the console. The gauges are: fuel level, water temperature, oil temperature, oil pressure, and amps. They're all the standard small 2 & 1/16 inch diameter units.
Problem is, this lift has to live outside in the weather. The existing gauges are rusty & mostly broken (lift is 40+ years old). If I replace them, I'd like to have them stay working and looking good.
Can anyone suggest either a method of sealing ordinary automotive gauges, or a manufacturer of "hardened" gauges, designed to get wet and not care, possibly specific to construction equipment? Any other solutions will be gratefully received!
All the best, Dave
