has anyone found a suitable replacement clock?

I managed to get the instrument cluster out.  With the instrument fuse out, the cab lighting harness disconnected, and  the lights off, my power lead to the lighting shows continuity with ground.  As I read it, that is definitely a short in the supply wiring somewhere between the fuse block and the instrument lights.

Add 1)Radio, 2)Clock and 3)Radio/LCD Clock Illumination Relay to your disconnect list, then take your measurement to ground. STG could be in one of those components.

radio and clock are out.  As far as  can tell there is no separate clock relay in the 86.  If there is, I can't find it.  And I have looked hard.

And I’m not home so I can not provide assistance at this time.

My plan is to either  identify and cut the supply wire nearish to  the fuse box, and try to determine which side of the cut the short is on.  and re-wire accordingly.

There’s no relays behind the drivers side kick panel or nothin? I know there’s a few relays there on my 88. 

[ruralandalone]

only 1 relay, and not for the lighting.  That is where is SHOULD be....

....oops. I was using the 88 Electrical Manual. No Radio/LCD Clock Illumination Relay. Somehow now I think I've already answered this once. ...oops again. I should know better.

[ruralandalone]

No, it was useful.  W/o your input I would not have figured that there was no relay.

I do wish I could figure out where point "F" was in the diagram that shows where the wires from the clock, instruments, radio and cab wiring join up.

I have an 86 wiring book for the MJ that I keep meaning to get scanned.

Taken from the 87 Electrical Manual. Circle with F in it.

 

[ruralandalone]

Thanks.  This means that the splice is in the harness, where I cannot easily get at it.

I have a workaround that I like.  I have run a new wire from the lights and am going to use a piggyback fuse to hook it in to the instrument light fuse location.  with no fuse in the original socket, I bypass the problem entirely.  My clock light can stay on and bright.
