Battery problems with Mr. Darcy

Posting from my phone So I won't go into much detail, but anyone have any ideas on what to do? I've been jumping for the past two days to get started. But randomly he'll start fine.

how old is the battery?

 

[ridenby]

Replace battery. Stock is 525 amps,get one with more amps,you and Mr.Darcy will be very happy.

I wouldn't be so certain about the battery fixing this. Just from looking at the graph where it shows a voltage draw when the starter is engaged. You can never have 0 amps with over 11V. You may have a corroded main power wire to the starter or a failed starter solenoid/relay. The reason I say this is a battery that has 11V will have more then 0 amps. Most batteries even discharged to 9V can still produce lots of current (not enough to start a vehicle but more then 0) Its never a bad idea to replace a stock battery to a higher output battery.


EDIT

Also that slip you have is DRAW test so if the power wire is corroded or broken there will be little to no draw on the battery.

I know it defies logic but I'm betting on bad battery. You did get hit. That causes batteries to go bad sometimes.

Its the battery. I had the same problem last week before I bought a new battery, and also when I had my 02 kj. I even had autozone test my first kjs battery and they said it was my alternator going bad, but after I replaced the battery I never had another issue

Get a new battery and go from there

Find a group 34-78 with 800 CCA. Interstate Megatron plus is one that should drop in.
If you have removable caps to add water, a hydrometer will give you a state of charge reading. Also take a voltage reading in the am after it sits all night. If the reading in the am is weak like 12.25 volts or less...manually charge it.
My Stock battery is 630CCA and is ok, but I manually charge my batteries often.
A load test should only be done with a battery after manually charging for 24 hrs @ 2amps.
Then you know best case scenario re your load test.
Generally batteries (lead acid) are toast after 4-5 years. (especially if they sit for periods, dont get charged much, or never get manually charges a couple time a month)
Nothing beats a 3 hour highway boogie to really charge a battery well.
This can also be accomplished by manually charging batteries and saves gas!

Alright, I don't completely understand everything said but I can answer a few things.

It's a pretty new battery, as in less than 2 months old and it's the 'gold' and the one that was there was a bronze or silver. I don't really know what that means but they convinced me it was better for a jeep when I bought it.
Also, I took more pics of my diagnostics slip. It's out of order but I tried to overlap so it all makes sense. Not to ke, but hopefully you guys will get it.

Could be bad connections between the battery terminals and battery posts,actually pretty common if any type of "anti-corrosion" spary was used on the terminals after the battery was installed.

But I have seen batteries test perfectly good but still be bad.

I would start by taking the battery terminals off and cleaning them very well with a wire brush(or battery brush) and a mixture of coke(the soda kind) and baking powder,rinse with distilled water,dry,and put terminals back on the battery and make sure they are tight.



Oh and the reason why you are seeing no amps on those readouts is the shop who did the test did not use the amp-clamp so it will read "0" amps.

 

[LibertyTC]

Agreed based on the latest shown printout, clearly shows a good battery voltage and available Cold cranking amps.
Get those terminals spotless, without any gunk as TJ mentioned with brush etc...
Also then make sure the terminals are tight/clean, and that the cables themselves have no cracks or corrosion of any kind.

 

[rockymountain]

Also, as said just because you have good voltage doesn't mean its a good battery. If the battery is a cheap one your accident could have damaged it. Just something to think about.

 

[Minimike]

it doesn't just have good voltage is also has a higher then stated CA rating even at 108F. Its not your battery as I stated earlier. like others have said inspect the battery connectors and main power wire to the starter.

I looked at the terminals (assuming those are the nubs I attach the jumper cables to) and they look nice and clean. I'm going to see if someone can check the wires for me. Mr. Darcy is starting sporadically. It seems to help if I tell him that I love him and he is the only man in my life, just ignore the boyfriend... I only had to get a jump once today, which is awesome. But I'm still going to get the wires checked so I can slow down on the sweet talking.

Eney luck yet ? I have seen bad spots in the starter do this. Some might rember the old tap the starter with a hamer trick. Maybe safety switch try playing with the shifter a little. Just some ideas with out looking at it.

 

[badkittystt]

It's been really random! He'll start, no problem at all, for a while, but once or twice a day I get nothing, just clicks.

The boy said he would look at it but he hasn't had time yet so we'll see if he finds anything. I'll have him read this thread for ideas.

 

[ridenby]

Change the battery, bet a dollar to a doughnut.

 

[Porkchop]

Im thinking starter if battery is new and tested and you run a jumper cable from the battery hot to the starter hot (by pass cable) and just clicks bet its the starter.
Hope this helps Mr Darcy

 

[badkittystt]

Alright, all bets are off! I've been spending way too much time with my jumper cables, and I've been having to drive Mr. Creep (the echo I used to drive) around when I don't have time to charge the batter, talk about embarrassing! I considered taking a picture of that for the JPOTM! But I digress... I've had the boy and some mechanics I know look at it and it's been an argument between the batter, connections, the starter, and voodoo. Finally somebody brought a batter tester when the car hadn't been running for hours and the needle pointed to WEAK! Which is pretty weak, so I took it to the place where I bought the batter and sat in the parking lot turning the car on and off to drain the battery and then had them test it. You know what it said?! SUPER WEAK! Well not really, but the tester said it had gone bad, so they gave me a new one for the price of on the house! That was early this afternoon and I've been running errands all afternoon, turning him on and off (giggity) and no hesitation at all! So hopefully this ends the drama of the battery, thanks for all the input!

I win!
