gauge cluster

[the big blue bus]

i got from the junk yard a cluster that has the tach that goes to 6000rpm and changed the odometer to read mmy milage and cleared the needles but now the gas and oil gauge dont seem to do anything but when i plug the orig cluster back in they work. how can i fix this? any ideas thanks

did you take off the needles from the cluster???

What year is the junk cluster from?

95 as well... and yes i did when i got the orange paint off them

I have diagrams for the '95 but they do not specify how far the tach goes but I also did find out that there were two different clusters used that model year so the only thing I can suggest it set them side by side and compare the circuit traces to find out if there are two signal circuits broken or the layout has changed and hot wire them to replicate the original by following its layout.

i hope i can fix it. i spend all that time changin the odometer to the milage i have and clearing the needls for when i get blue leds. they workd before i took the needls off im pretty sure so i musta messd something up

only thing i can think of is when you take off the needles, maybe you didnt put them back on where they were exactly in the first place.. soo say the fuel was one a 1/4 when you got it, you took off the needle and placed it to full. maybe it messed it up??? i have no idea. weird.

That is very likely too

made sure i put em back on right... the fuel gauge has like play in it now

idk i dont screw around with needles. The fuel gauges on these trucks have so many problems anyways, thats why i just swapped out for escalade gauges and called it a day. No screwing with the needles and getting them off center or what. They are temperamental tho.
