I'm working on a 1992 Dodge Dakota LE 3.9 V6. The speedometer and tachometer seem to be working OK. The battery gauge seems to be OK, the fuel gauge stays on empty. The temp gauge stays on normal, even with key off. I'm pretty sure if the fuel gauge isn't working it could be electrical or mechanical depending on the sending unit in the tank, how is the temp gauge controlled? Also, is there anywhere I can get a hold of the owners manual in pdf format, I've done a lot of looking and haven't found one yet.

Thanks
