Engine Mechanical problem
1979 Jeep CJ5 V8 Four Wheel Drive Manual

New battery, new starter, new solenoid, new alternator and belt... she still won't crank, just sits there and grinds. If you boost the battery she fires right up.. I'm at a loss.

OK drtygirl79,

Dagnabbit...........I'm waiting for the smoke on the LZ, and you establish a new LZ, I hovered around and luckily spotted the new one.

I want you to check out the stuff I give you below, then TEST what I tell you at the end

THEN GIVE RESULTS---HERE!---AT THIS LZ!

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!!!

TAKE STUFF LOOSECLEANTIGHTEN WELLDO NOT JUST PASS ANYTHING 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".

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

IF THIS IS A CJ---HOOK UP EXACTLY AS IN THE PIC ABOVE......NO WHINING!.....JUST DO IT!

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 SOLENOID IS ACTIVATED, IT THROWS 12V TO STARTER USING THE LARGE GAUGE CABLES (1) POS FROM BATT--THRU SOLENOID 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

Whaddu mean "GRINDS" Starter not engaging?.....or rotates engine and just will not BUST OFF?

REMOVE "6" and TEST "D", tell me voltage while turning the engine over.

DO IT!

Your Turn

Oh, and just so you know. I most likely will whine a little. Probably curse some too. The Solenois is new, changed it when I changed the starter.
