Can a 80-86 diesel have no power?
Can a 80-86 diesel have no power?
80-86 doesn’t have a bulkhead connector like the 87-97 trucks do. Even though you just replaced the batteries, disconnect them and load test each individually. If one has a shorted cell, it will take out the whole system.
Why is there no power in my car?
No electrical power even with a new battery that I bought because of the problem. I checked the new battery and it has a strong spark, but not even the lights work…NOTHING WORKS. Is there a main fuse or something because no matter what I do I can’t get anything to work. I even jumped the 2 large connectors on the solenoid and nothing.
What to do if your truck has no power?
Start by cleaning all the battery terminals. That way you know there is power that far. Then turn on the key and then jump the starter solenoid on the passenger fender. What you need to do is pull off a small wire and jump the heavy leads to that small terminal. I just use a screwdriver to make the jump.
What are the symptoms of a bad ECM power relay?
A bad relay may cause the vehicle to crank, but not start, or sometimes not even crank at all. 3. Battery drain or dead battery. A failed ECM power relay can also cause a battery drain or dead battery. If the relay shorts it can leave power on to the computer, even when the vehicle is turned off.

Is there any electrical power in my truck?
Truck has no electrical power, I mean nothing! Discussion in ‘ 6.9L IH & 7.3L IDI Diesels ‘ started by spencnaz, Dec 20, 2007 . Put in a new battery this week to replace an old one.
