SOMETIMES IT'S JUST A MATTER OF GETTING IN THERE, AND GIVING IT SOME "TOUGH LOVE"

TRY THIS STUFF, BE DETERMINED WITH THE CONNECTIONS!

THIS IS SORTA GENERIC

YOU COULD HAVE OTHER PROBLEMS

INSURE YOUR BATTERY IS GOOD. AND ONCE YOU ARE RUNNING, YOUR ALTERNATOR IS CHARGING (CAN BE CHECKED FOR FREE AT MOST AUTO PARTS STORES)

USUALLY ITS SOMETHING EZ TO DO--IF YOU DO IT RIGHT

YOU COULD HAVE FAULTY RELAYS OR FUSES. SAVE RELAYS FOR LAST! (IF ANY)

CHECK YOUR FUSES!---YOUR OWNERS MANUAL MAY SHOW YOU LOCATIONS THAT YOU KNEW NOTHING ABOUT!

REMOVE AND REPLACE "SUSPECT" FUSES SEVERAL TIMES--THIS MAY SCRAPE OFF CORROSION AND GIVE THEM BETTER CONTACT!

THIS WILL WORK FOR YOU, PROVIDED THAT YOUR BATTERY IS GOOD---OR YOU CAN BE JUMPED OFF!

REMEMBER "NEW STUFF" CAN BE BAD TOO!

YOUR STARTER MAY BE BAD!

YOUR SOLENOID MAY BE BAD!

RELAY PROBLEM

EVEN IGNITION SWITCH

BATTERY COULD BE BAD!

BEFORE YOU START BUYIN STUFF

Try the stuff below (actions),

IN MOST CASES THIS IS THE PROBLEM!

PEOPLE GET LAZY!----THEY DO NOT ACTUALLY DO THIS STUFF

IT BITES 'EM IN THE BUTT. THEY COULDA BEEN RIDING LONG AGO!

TAKE STUFF LOOSE (REALLY! YOU ARE NO EXCEPTION!--EVERY ONE OF 'EM!) CLEAN"SCOOCH" THE CONNECTORS AROUND----TIGHTEN THE NUTS OR BOLTS WELL!

DO NOT JUST PASS OFF ANY BIG CABLE CONNECTION AS, "IT LOOKS GOOD".

PAY SPECIAL ATTENTION TO THE BATTERY POSTS---CLAMPS---CABLE CONNECTIONS TO THE CLAMP (I'M TALKING ABOUT THE OLD STYLE "SQUEEZER" DEALEES, CLAMP TO CABLE)

IF YOU HAVE SIDE POST TERMINALS---TURN THE RUBBER INSIDE OUT/ REMOVE THE BOLT/ SCRUB THE FLAT CONNECTOR WITH A WIRE BRUSH OR SCRAPE IT WITH A KNIFE, TILL IT'S CLEAN---SAME FOR ITS MATING SURFACE ON THE BATTERY!

MANY TIMES THERE AIN'T MUCH SLACK IN THE CABLE----NO WHINING!---YOU GOTTA GET IT CLEAN, ESPECIALLY IF YOU CAN SEE "GREEN CRAP" CAKED ON 'EM!

YEAH, IT'S NOT EZ TO GET IN THERE, BUT LOOK AT WHAT YOU WILL GO THRU IF YOU DON'T!

THIS IS WAR--YOU GOTTA CHECK IT ALL--ANY CONNECTION---POSITIVE OR NEGATIVE THAT A BIG CABLE BOLTS TO. GET YOUR HANDS DIRTY!

IF A CABLE GOES TO A BOX--IT GOES ON THRU IT---CLEAN CONNECTIONS COMING AND GOING---TO WHERE EVER THEY GO!

EVENTUALLY YOU WILL REACH THE STARTER CONNECTION (POS)AND THE ENGINE/ BODY (NEG)

DON'T TELL THE SHOP, AS YOU GIVE 'EM YOUR $$$---WHILE WHINING---"I WAS TOLD TO CLEAN THAT CONNECTION, AND I DIDN'T!"

AS YOU PROGRESS, TRY TO CRANK HIM UP---YOU MAY FIND EXACTLY WHICH CONNECTION WAS THE PROBLEM!

I'VE SEEN THIS SAME CATASTROPHE, MANY MANY TIMES (I SAW IT NOT LONG AGO), AS I WAS ABOUT TO "CAR DOLLY" A FRIEND, WHO SAID HE HAD A MAJOR PROBLEM. I FOUND OUT EXACTLY WHAT WAS GOING ON, SO I DID THE INITIAL DIAGNOSTIC CHECKS. ALMOST IMMEDIATELY I FOUND IT WAS THE SIDE POSTS ON THE BATTERY CONNECTIONS)

. AND IT'S SO SIMPLE TO FIX. SAD THING, WHEN I GOT THERE, NOTHING HAD BEEN DONE 'CEPT AN ATTEMPTED JUMP START.I WAS GONNA HAVE TO PULL HIM 40 MILES, HE WASTED 3 HOURS OF MY TIME. LAZY, LAZY, LAZY

YOU COULD BE RUNNING BEFORE YOUR "CALVARY" ARRIVES!

IF I HAD A QUARTER FOR EVERY TIME I HAVE ENCOUNTERED A BAD STARTER SYSTEM CONNECTION---FIXED EZily WITHIN 10 SECONDS TO 3 MINUTES TIME.I'D BE SO WELL OFF!

RETURN WITH GOOD NEWS!

OR YOUR NEW FINDINGS AND WE WILL CONTINUE
