A couple of days ago i post a thread about me removing my battery and found a sensor at bottom of tray. The reason i pulled my battery was to clean terminals and get it tested, a maintenance free battery. The truck has been dragging a little on the old starter.

I went to start it an click click click click real fast. Ok starter first to mine. I check my batt with multimeter 12.45V tap starter samething. Remove, replaced starter samething. Clean battery term it started.

Today clicking again. I've checked for loose connections and no busted fuses. I dont have a code reader but turned the key 3X's eng light flashes 10X's any idea? What is this code? Or what's going on?

 

Sounds to me like its the battery? Maybe reads 12.5 volts sitting there but when a load is applied it drops big time. maybe a bad Cell or something? Take it to auto Zone or Advanced and have them put a load on it and check it... its free? They also read codes for free if there is any.

 

Bat took a load test and came back fine no drop

 

The clicking is what a starter does when it doesn't get enough amperage. You need to have the batt load tested..while the voltage will read fine you need an amp meter to check it out. replace the batt and you should be golden as long as your cables are ok...I'd check those first for any corrosion or breaking

Edit: Just saw your post...

Run a helper cable from your pos term on your batt to the positive post on your starter...a jumper cable should work fine...also run a helper cable for your ground to the engine block and see if she fire...

 

Look for voltage drop when cranking.

Using a multimeter pace one end on the batt POS and the other end on the starter POS then crank if you see more than 0.5 volts then you have a cable problem on the Positive side.

Do the same thing again but on the batt NEG and starter body then crank if you see more than 0.5 volts then you have a cable problem on the Negative side to the engine block (or Block to starter mounting).

Also check from the centre of the Battery termanal to the battery clamp (when cranking)
Batt term POS to POS Batt Clamp you should not have any voltage drop at all
Batt term NEG to NEG Batt Clamp you should not have any voltage drop at all

 

I replaced the battery. There was no voltage lost from posi to posi nor neg to neg. All cables were tight. The batt must had a bad cell because it took a load test a couple of days ago, "freaking maintenance-free batteries" is what came with the truck. Advance did the free load, starter draw, charging test all good.

Thanks all

 

Sounds like a bad alternator, batt checks out okay, starts good then doesnt start, use the meter on your alt, if its lower than 13.5ish at idle then you prob wanna replace it

 

Well I guess I jinks myself. I went to start my truck this morning and "Click" I was pissed and now going to be late. Checked the voltage drop and got 11.59 volts on the Batt POS to the POS starter terminal. Took the cable off the starter and could see that the toothed nut had been arcing out to the cable and was totally ionized and carbon tracked. Cleaned the nut, cable and terminal all up with some sand paper and was good to go.

 

Click click click is better than click click boom

Glad you got it fixed.
