Title: MC 9 Tell Tale Lights and Circuit #'s
Post by: BC Bus on November 23, 2009, 07:56:52 PM
I am working on the Tell tale lights on the left hand side of the MC9 dash.  I am putting the tell tale lights back in the dash and am wondering if someone has a list of the circuit numbers and which socket each light goes back in.  I other words "what tell tale light is it." All of the lights are unplugged and
All of the wires have numbers on them marked with the little aluminum tags.

I can find few in Da Book, by searching each schematic but not close to finding all of them

My MC-5 manual has the tell-tale circuits mostly listed in the front junction box connections list.  On the off chance that they are the same as MC-9, here is what I find at a glance:

stud       code     function
11           5         24v discharge tell-tale       
13           38        low air tell-tale
26           39p      emergency brake tell-tale and fast idle load
27           35        High beam tell tale
36           11        stop lamp tell-tale
39           32        11 lb oil pressure tell-tale
41           46        back up lamp tell-tale return
47           39T      Emergency brake tell tale and fast idle return
50           60        3 lb oil pressure tell tale
52           52        fog lamp tell tale


"code" is the number on the metal tag on the wire.

Thanks for the replies guys. Brian listed exactly what a lazy person was looking for.  His list will sure get me started and maybe the rest will be trial and error.

Great board.  I don't post much but I read it religiously.

I just checked my MC-9 Manual (January, 1980 version) and it lists all of the same stud/code/function that Brian listed in his post.  The only difference is the Emergency Brake Tell-tale shows as code 39 (without the "T").
