Electrical problem
1989 Ford F150 V8 Four Wheel Drive Automatic

My question involves trouble shooting. This morning I parked my truck at the farm. Returned to start it a half an hour later, and it was completely dead. Nothing was happening. The battery is less than a month old. Thought it possibily be in the ignition switch, replaced it no luck. Decided to check my fuses, all good. Tried to turn on radio, headlights, ect. Nothing. Can you help me. Thanks Brad

To keep me from hunting and pecking all night, I grabbed an answer, I gave to somebody else. See my profile.

All may not apply, pick through and use generalized part of my answer to Jill.

Let me know if it helped you.

I know your Solenoid looks different, they do the same function! Pasting----

Jill, see my profile, I believe if it were a fuse, It wouldn't work at all. I do not know your rig very well, however, I saw your question, unanswered, and thought MAYBE this might help you, get your Baby back on the road.

If the "CRAP" on down doesn't help, It could be the "cable" to the starter (clean/tighten) or the solenoid itself----even the starter......Try this stuff below 1st!!!

See my profile. Yours may not look like this, but TAKE STUFF LOOSECLEANTIGHTEN WELLDO NOT JUST PASS IT OFF AS, "IT LOOKS GOOD".

Do not leave off where the Battery cables connect to the Battery clamps! (not the posts) Do them too!

While you are at it, Both ends of Pos cable, Both ends of NEG cable.

If you still have the problem, you're probably looking at $20 to replace the SOLENOID. Follow Battery Positive cable to find it.

My stuff may be OVERKILL, but at least you will know what everything is and does.

Like my newly made "NELSOMATIC" stuff? I am cyber stupid, and did that! Keeps me from hunt and pecking so much!

Please Reply, Good or Bad.

I will continue to try to help you through your whole ordeal, even if this didn't help you. Just continue to Reply at "reply to question".

Love, Turddog

Follow POS BATT CABLE, It will end up here, at the SOLENOID, looks vary, function is the same.

"FORD TYPE" SOLINOID SYSTEM, YOUR ACCES., MAY VARY

1) POSITIVE CABLE FROM BATTERY

2) OUT TO STARTER MOTOR

3) ON MY JEEP, THIS GOES TO THE ALTERNATOR

4) THIS FEEDS MY FUSEBOX (ALL OF MY ACCESSORIES)

5) "S" WIRE IS FROM KEY, 12V ONLY WHILE YOU ARE "CRANKING"

THIS WIRE ACTIVATES THE SOLINOID'S ELECTROMAGNET, WHICH IN TURN, CONNECTS---A & B INTERNALLY (ONLY THE 2 LARGE GAUGE CABLES CAN HANDLE THE AMPERAGE THE STARTER "PULLS").

WHEN THE SOLINOID IS ACTIVATED, IT THROWS 12V TO STARTER USING THE LARGE GAUGE CABLES (1) POS FROM BATT--THRU SOLINOID INTERNAL CONNECTION--(2) TO THE STARTER, WHILE KEY IS IN "CRANKING" MODE.

THIS IS THE TOTAL REASON FOR A SOLINOID, BECAUSE IT WOULD NOT BE PRACTICAL, TO RUN THE HEAVY CABLES TO AND FROM YOUR KEY SWITCH.

6) "I" WIRE (OPTIONAL), FEEDS COIL "FULL 12V", ONLY WHILE "CRANKING", AFTER YOU RELEASE THE KEY, THE COIL REVERTS BACK TO REDUCED VOLTAGE, SUPPLIED BY YOUR KEY IN THE "RUN" POSITION.

7) "MOUNT" GROUND, UNIT MUST HAVE A GOOD GROUND (BATT. TO ENGINE, ENGINE TO FRAME, FRAME TO BODY [ALL MUST CONNECT, SOMEHOW] )

(3 & 4, ON MY JEEP) ARE FUSABLE LINKS, ALL ARE NOT MARKED, MY #3 IS, #4 IS NOT....ITS SORT OF A "WIRE" FUSE.

IF THEY ARE GOOD, TUGGING ON THEM WILL BE JUST LIKE A WIRE, WHEN THEY ARE "BURNED UP", THEY WILL STRETCH OUT LKE A RUBBER BAND.

TURDDOG DOES IT AGAIN!

He is INCREDIBLE!

Thank you for the outcome response!

I bet I have sent that "NELSOMATIC" Solenoid explanation to 20 peopleNOT ONE RESPONSE!

BACK TO YOUWHAT CAUSED THAT PUPPY TO FRY?

If you just "BYPASS" it, Is your harness gonna start "smokin", FLAMES?.....NO MORE....MR. TRUCK?

See if you can find the source that burned it up, or at the soonest time, REPLACE THE LINK....just to protect that circuit!

Thank you so very much for the reply, I thought I was Losing my touch!

Love, Turddog
