I own a 1990 Dodge 250 with a 5.9L desiel some thing shorted on me lastnight and can't find where. It shut the hole truck down except the radio. Does any one have a wireing diogram for this truck as I have looked every place that I can think of and no luck. This is a Canadain model please help so that I don't feel like this !!!!!

 

Did You Check All The Fuses/relays????

 

Do you have lights? anything electrical? If not, check the connections coming off the battery including the fusible links. If you have power to everything but the engine wont start, check the connection at teh Fuel Shut Off Soliniod, and teh wiring between teh starter and starter relay...

 

Checked The Relay In The Fuse Box And Ok I Think????? Switched It Out With Another And Still Nonething?

 

Relay in the fuse box is fine higher up on the colomn.

 

Check the fusible links. They are located in the main wiring harness under the hood, between the battery and the driver side hood hinge. They are actually tie-strapped to the outside of the harness. Give each one a little tug to see if it stretches, because the wiring can melt and sever, but leave the insulation intact.

 

Tried that and all good there it is under the dash I do beleive because I herd it fry then truck Quit no power to the gauges or the starter just headlights and heater motor in the dash and interior light nothing else has power????

 

Any body got any other good ideas and thanx for the other tip guys but still no go

 

well it sounds like ( if you heard somethign fry under the hood) that it is time to start tracing wires. Start a the fuse panel and just follow each wire to the ignition system looking for burnt insulation or breaks.
Be sure to check the fuse block itself and make sure you dont have a short across there.
Anything like that tho should have blown a fuse.......
IF it fryed enoug for you to hear it, you may be able to smell a burnt smell from teh area wher you have a problem.

Good luck!, its not a fun job

 

BTW, is this an auto or manual? if manual, you may have a bad clutch interlock switch. This prevents the engine from starting unless the clutch is depressed., an dwill lkill all power to the ignition is it goes bad. The switch is located on teh clutch pedal mount against the firewall. You can try jumping this and see if that solves the problem.

Fill out your signature so folks can see what you have, it makes it easier to help you

 

Found wire diograms that I needed guys thanx to all!!!!!

 

Hope you've found success by now. Another area to inspect is the connector to the ignition switch. Sometimes you can even see a melted spot on the lower steering column shroud. Remove the shroud, disconnect the ign. switch connector and inspect for discolored terminals or an obviously overheated wire. Usually it's the blower that causes a meltdown in this area, but you say yours is still working, so it may be a different circuit overheated in the same area. Tilt steering can cause a problem here too, the wires may fatigue and break, or a terminal may become pulled out of the connector.

 

No tilt plan jane found that I had 2 fuseable links under the hood near the firewall that had fried and a burned out colomn ignition switch that was fried all is well now thanx for asking and thanx to all for the help could not ask for a better group of people to ask for help

 

Be sure to find out why the fusible links melted before you drive off down the road into the sunset!
