How do i tace the cuuse

Trace the cause of a lamp fail 97 wrangler.
fuse blow for shorts, (preventing the fire)
so, there are only 3 ways to find shorts,

1. visual inspection ever inch of shorted wire, (luck happens)
2. pull all loads off the wire feed, is short not gone (BINGO?>)
3. use an AMMETER, this is what we use, to get them all.

one nice way to find shorts,(not wanting to blow 100 fuses)
is to remove the blown fuse ATC and put in a Circuit breaker ATC fuse in that place, not it trips , cools off and repeat the trip
this allows for fast testing (meter) and pulling loads, checks.

your car is jeep TJ
and the wiring is free here.
the schematic tells you all things that can short to this node.
click wiring,

Tail/park shorts, (lots of loads, the highest of all wires it is)
answers USA only not export and no DRL light option.
we are tracing the complex path called PARK (tails)
see chapter 8W that be IT.
and page. pdf page # 8w-40-7 (pdf #93)
turn the dash dimmer to lowest, still blow fuse.
no, then the short is not in cab (easy huh?)
so parks are shorted, see 8W-50 (pdf 134)
see park there/ see those fues # which one blew, that is a big CLUE.
my guess is fuse 1, (others are head lights)
F1 blows
main HL switch park pin 9 ,black yellow wire feed.
see that?
see 8w-50-4 then page 5 , see all rear parks.
then see page 8w 70-20 for fogs.

there you go... i cant teach you how to use and ammeter.
so google that.
see all those junction C connectors, all can be pulled to isolate that short.

see connector C110 , pulling that isolates front parks
conn C322 , pulling that isolates tail parks.

as you see park feed is hug (simple) but huge, lots of places to short
and big time short if trailer wiring hacks are on car. look first.
