Newbie here...sorry if this is totally trivial. First off, i have searched the archives on this and found a good bit of info...but still have an error. on my '96 '80 i have not been able to get the center diff light on the dash to light, and therefore, have not been able to get the front or rear lockers to engage. What i have done so far - shift into low and drive around, make turns etc. (it seems to be in low as it is pulling much harder and shifting differently) - no dash light. I have pulled the input into the t-case on the front by the drive shaft and shorted across it with a paper clip. I get a clicking in the DS kick panel, but still no light. I have checked all fuses and they seem to be good. Any suggestions on how to proceed next?
