Looking for a schmetic for a 5x157a - Cars & Trucks

http://www.bbbind.com/free_tsb.html free wiring diagrams !

oid is there way of saying hot at times,(others use)
IOD, is correct name
ignition OFF, drain
these fuses are pulled when car leaves factory , keeping battery fresh, then put back , at dealer
the are are just keep alive features, (electroncs)
1: PCM ,memory (errors, and fuel trim learning values)
2: radio stations,
3: NAV settings;
4: all the various brains, in system, pcm bcm , tcm , an others)
Allen Turning called it a brain, so he wins, (lol)
all feature on car with LEARN in the descriptions, is this.
IOD fuse.
but you can read the schmetic right> and see what loads connect to your fuse , right? and then pull it and see if current falls to ok.
my guess, (i fix ECUs for years, and lots of controllers) at component level for 50 years. ) the electolytic caps some will go bad at too cold a temperature, good ones go to -40F or -40C (crossover) some china clones of these parts are pure rotten junk.
not even tested, there, they just clone the words, .....

finding which cap is shorting is not easy. (too intermittant, even hard for me with my fancy gear, (i have current logger, i designed)

post the real location of the fuse , a photo is best.
then we look it up
or you do it at alldata.com
(google finds it in 1/10sec)
im hoping its some cheap radio doing this
so unplug it and see.
unpluggin pCM or BCM etc is not going to work, as car will not run.


i think normal current is about 0.020 amps max
ase/sae , averages. 20 mA.
blowing fuse is gross short.
i hope it says shorted,so is 1000x easier to find.

sure you, can a schmetic of what.
freon loop
mech, parts
elect. schematics??? electronics controls. , air controls
this is called a FSM. ever heard of that>?
here it is , read the HVAC pages then the wiring chapter same topic
why not post symptoms and let me tell you how to diagnose AC.

bingo. the whole 100 pages. on one topic, or more.

if you dont know HVAC, why not just post the symptoms..
the FSM is for savvy mechs. with HVAC training.
im good on the electric side, and can also tell you if the loop is failing.
but im not a Freon LOOP guy, i do electronic controls of all kinds.
retired, now.

look on the sides and front of the radiator banks it should be there.it will have a big nut on it with a 2 or 3 wire plug on it.go to ur parts store and have a look at what it looks like,this will help to know what u looking for.if its not there then look on the thermostate housing it will be there.

Can you take the van to a local family owned shop near by that could hook them up for you reasonably? Google the manufacture and contact them or take it too a dodge garage? The wiring from the motor should be very basic, like 1-3 wires and not costly or time consuming to hook back up. What brand lift do you have? The more info you give us, the more help we can be!

Unless you buy a complete factory wiring manual,
the only other choice, is to get part of the wiring you need
off the ALLDATA or similar data base ,at a local repair shop

I have no idea how you let that happen
Where you not there & watching him?
You got about the worst possible vehicle
problem a person could have

You need to look under the rear of the vehicle and look for bent trailing arms or anything else that could look bent.If you not sure what to look for just look at the other side that is straight.Hope this helps.Good luck.

A new circuit board , circuit board voltage regulator
look at the schmetics and see if there is a common ground or source of B+ that they all share, see what hind of shape its in.

chiltom manule will show the hole sys sold at chapters
