there is one wire coming off the ignition coil meter fuse (15amp) it is black with a white line, it keeps blowing fuses is there supposed to be another wire coming off of the ignition coil fuse?
thanks
thanks

The wire feeds many components through splices such as ignition coil, generator, fuel pump relay, etc. You have an 8v or 16v?
95 geo tracker 2 door, 4wd, automatic trans, 16v 1.6l. realized theres a common ground for the block, still blowing fusres, is it the fuel pump relay? corosion on the fuel pump ground? pulled the dash and have access to most of the wires but have not found anything burnt or shorted yet, also have random wire and random clip near carb that i do not know what it does, but it looks as if it has been cut or ripped somehow.
my sig has my web site. it's all there.
all things make motor go are there. see schematic section.....
same wire as you told me black with white stripe in post 1.
see it, see it the O2 heater , left side just below pin A23
click this link, just below this line.... bingo, the whole EFI wiring .

100% percent BINGO on that.
if air enters ( yes exh goes negative in pressure) the 02 WILL RAIL LEAN and freeze there.
or worse.
all cars all o2 sensor from now to future.
AIR has oxygen, if it enters , the sensor cant tell what you did, it only reports fact.
its just a sensor.
no exh. leaks from the exh. valve ports all the why to the CAT honeycomb block.
none.

ok, forget obd1, (yes yours is)
you need to
1:look at the wires on the O2 sensor. are the burned frayed or damaged?
yes, correct that.
no , then unplug it .
if unplugging it , corrects the fuse blowing then that is the problem.
if unplugging it does not correct the fuse blowing then you need to unplugg all things on the black-white feed line.
see that schematic, see the black -white feed,
any place on it can short to ground,
finding it takes testing and not guessing.
one unplugs things to find a short.
you dont have a guided directional amp meter like me, so you can do that.
you must have do it the old school way, "isolation"

no , the exhaust leak will not make the sensor short , unless the exh. gasses are blasting directly on to these tender wires.
the O2 heater draws 1 amp.
the fuse is reated for 15amps
you have hard short and is easy for any tech to find it.
get help.
the O2 can actup for lots of reasons.
but do not replace it unit you find who is shorted.
the ignition coil primary could be grounded out , see it? there?
but 1000 times more likely is the 02 shorted in side or its wire set.
there may be other places it can short but that gets real complicated.
just unplug it and test.

whohaahhh progress.
lots. since yours is the rare fail , so can be ANYTHING on that feed.
too many drawings , many are blk-white , all can short.
so will list them.
DRL lamps controller ( if you have it)
A/T tranny brake switch. with foot off brake THE TCC relay shorted or tranny tcc solenoid shorted, ( everytime over 45mph , boom goes the fuse)
audio alarm module. the thing that chimes when seat belts arent fastened.
Main relay (runs ECU) only of the coil is shorted to body.
fuel pump relay , only if coil is shorted . fuel pump cant blow this fuse unless this relay is belted blob of slag.
oxygen sensor heater ckt ( top fail)
Ignition coil.
Noise suppressor ( not likely, near impossible and hard to find )
Generator ( alternator regulator inside it , is shorted , unpug the rear plug on alt))
last: instrument cluster shorted. it has a blk-white feed on pin 5 that runs all the lamps and meters in I/P cluster.
