pull the connector down and use a piece of wire in place of the switch

I about asked a dumb question, but it just clicked in my head on what you meant. so anyway, I'll try it monday and see what I find. have you got any other ideas where to look?

leolkfrm · 02-28-2009, 03:00 PM

looks like crab gave you a pretty good checklist already! have you been through it yet?

batty1214 · 02-28-2009, 03:04 PM

no, I started on it at 1:00 friday afternoon and the work day ended at 2:30, and I replaced a cracked splitter board at the back end hopping it was the deal.... they asked me to come in and finish it, but the mine operations ticked me off so I am gonna let them pile into extended cab pickups until monday, cause me and the wife just closed on a house and uh........I have alot of excuses that I have, not to help the guys that know nothing, but tell me how to do my job.

I just am looking for a good place to start on monday, so I don't waste too much time on it

Don't screw with the brake switch - it's gold. See "A".
Hot at high stop means you don't even have to check "B" or "C"
You say you have hot at both sides "D" so that leaves "E" "F" & "G"
( Not an excuse to say E F n G )
This pic is the same as the list I gave above.
Note trailer and hi-stop are on "B" fuse not "D" fuse, so are seperate.
Just track wire from "D" fuse.
(of course you checked the common bulb ground right?)

batty1214 · 02-28-2009, 07:49 PM

the only grounds I could find is the one coming out of the main harness a little ways up the line..... is there another one in there somewhere?

Tail/stops etc share a ground so easiest is pull the bulb
and check the socket connects to ground.
Unneeded check if other half of bulbs there are working.
See how they all share that ground at very bottom of pic ?

Should be one good is all good, unless by an incredible freak occurence,
both stops lost their grounds at the same time seperate places.

You should also check that the right bulbs are installed.
Not likely problem, but you will kick yourself if that's it.

well, backup,marker,turn signal all work. just not the brakes

Good then check for hot at "E" as it goes through that underhood fuse block thing. Most likely a pulled wire. Ground seems to be ok.
