How hard are gauges to work on?
 

Would mechanical gauges like pyro, boost, F.P.,and trans temp, be easy to work on, in the event they failed? Just curious how they actually work. I'd like to stay away from as much electronics on this rig as I can, and stick to things I may be able to fix if nessessary, just don't know the inner workings of the gauges very well ;) Could anyone point me in the right direction here?
Thanks

I have no idea I figgure if I ever had a problem I would just get another gauage

me too.. the gauage it self usually is only 20 or 30 bucks

Guages (including mechanical) are in most cases throw away items. Even if you could fix them, without special test equipment, you would not have any idea if they were reading correctly. About the only servicable part are the thermocouple probes - which you can only replace (but again, you need special test equipment to tell if the probe is good or not).

Carl, I see lots of mods on your truck - please tell em that you have a pyrometer to go with your fuelling mods. My point is, a #8 plate can get real hot in a hurry.

There is not really any servicable parts in teh gauges. Parts would cost more than the gauge itself if you could even get them, As stated above, even if you worked on them you could calibrate them.
