im so sick of this dash of mine.....you guys said the volt guage wouldnt work if the fuses at the fenders were blown...so i check them and they were just completely gone....so i get some fuses and start to put them in....fight with the first one like 20 minutes and take the other one apart and it breaks in half.....so i stare at the thing for a while and try to pry it out with a freakin screwdriver some needle nosed plyers etc etc. then i get the idea to get a drillbit and drill it out...works like a champ...put the new fuse in then try to put it together and it wouldnt go...so after about 10 minutes i put a drop of PB on the rubber and it slides together instantly. so i go in to start the motor and the guage still doesnt work....my alternator is good because it charges my battery and runs everything...the printed circuit looks good....is there some kind of ground strap im missing? my guage lights dont work either...when i turn it to where it should be brightest lights if i put it just right i can get them to come on real dim. i changed the dimmer switch to one i know worked in another truck and now it does the same as the first one...my tach works because it's directly wired and this is the only other electrical guage besides fuel that i dont have hooked up yet.
