Jeep battery voltage
So after my battery testing good and
alternator good also i talked to some
people who think the terminals are bad
which makes sense from the sypthoms.
But i also noticed that the battery gauge
flucuates? Can this be caused by the
terminal ends not charging right ?
any electrical connection should be clean and tight , you need a multitester too see if it matches the gauge , batt, should have 12.5 v at rest and 14+ when it's running for a good alt. if you get good at fixing those jeeps there's plenty of work
We came to the conclusion that the terminal ends need replaced can this be causing the volt gauge to flucuate up and down slowly i assume it can because if the terminal ends are not providing enough conection then they may not be charging correctly
Be aware that your alternator may be putting out the voltage, but not the amperage. This happens a lot. Just because it shows 14 volts doesn't mean the amperage is there to support the system demands. Example: lights, ignition, heater, and any other systems you may be using at the time. Check the amperage output on your alternator.
Iv had it tested it autozone and the battery too both are good.i also work there and some guys there told me that there alot of problems with those lead jeep battery terminals which explains alot because sometimes i go to crank car but it dosent start it just clicks but lights and evrrything are on . So then i went to test battery and got a inaccurate reading saying it was 0% charged but it started right up . I think it may bs the starter to but why would the starter cause the volt gauge to flucuate ? So im gonna replace battery terminal ends and go from there
So after changing the terminal ends my battery tested good. Alternator passed regulator diodes but failed ouput
I believe the internal regulator of the alt. needs an initial jolt to start working , aside from the batt. + it already has
So since it failed the ouput that explains the flucuatinf of the volt gauge because alternator is not outputing enough so guess i need a new alternator correct?
if you only have the 12,5 batt, voltage when the motor is running then I'd say the alt, is bad but didn't you have it tested ? scan for codes even if the light ain"t on , How did you test the batt, to get a 0 ?
Yes i tested it again . And it shows the alternator is not putting out enough output i work at autozone so i used our tester and it shows the battery was good but was 0 percent charged , then i tested alternator and it passed voltage regulator and it passed diodes but didnt pass the output test. With the volt gauge flucuation i belive it is bad
Belt is tight tensioner pulley and stuff was replaced not to long ago
Ok so iv replaced the alternator but gauge still flucuates from 14 to alittle over could the battery be bad ??
Its normal the volr gauge to flucuate alittle evn while at idle with no electronics on no heat or anything just car running
So its still doing the no crank no start sometmes it will start right up and other times it will not crank or start just one click All elctronics work headlights are normal . But after i try it about 5 to 10 times it will start up ??
that sounds like a junk starter , some are junk out of the box , I've found a distributor of OE parts that are a little more than autozoos but not as much as the dealer , this is where I'll be going to get every part I need as I'm sick of crappy parts that last one year or can't take the heat , may be an exorcism needs to be done who knows , good luck
Any follow up I’m having the same issue with mine ???
