Ravelco.com works for me:rock::rock::rock:
You need to search thr forum and look for the Service Manual. I have posted it in the past. I have no idea what year truck you have so I am going to give you the page number from the 2005 Manual. Goto page 1505, section 8j Instrument Cluster.
The service manual gives you all the wiring schematics to start looking where they F'd up your wiring. You need the A-hole who installed it to answer questions about what he F'd with so you can undo the cluster they have created. It may be something simple like taping of the power used by the instrument cluster and putting too much load on it and taking power away from the gauges.
Just search for the manual. It will help you. You are going to need the wiring schematics to properly figure this out. Not guess and splice your way through it. That is how it got F'd up in the first place.
I've taken a bunch of those out of cars. You would be surprised how easy it would be to bypass those. Also seen those caps melted because to much voltage running between pins.
melted caps????:dontknow:
don't see the too much voltage part, amps yep.:rock:
sounds like piss poor install. its rated 10 amp MAX:toilet:
they are set up for the quicky guys that try to steal your ride
said voltage because most people don't know what an amp is
And yes, very poor installs on the ones I have removed.
