SOURCE: voltage irregularity

Well that's ABSOLUTELY NOT TRUE, the voltage regulator is in the ALTERNATOR. This vehicle needs an alternator and that should take care of this problem. Good luck and thanks for using FIX YA

SOURCE: '97 jeep cherokee sport reads negative on battery

Have you checked the battery cable connections? If so, check the negative battery cable from the battery to the body and from the battery to the engine for breaks or if they are loose. If good, check the positive wire going to the starter, there is also an inline fuse in the pos. cable to the starter that might have blown. But, my guess is that the battery cables are loose. Hope that this helped, good luck. Let me know how it went. I'll be here if you still need me.

SOURCE: charging

Most likely it is the voltage regulator that's going bad which allows overcharging. this is inside the alternator, so it most likely needs replacement. you could pull it out and take it in to most auto parts stores and they would check it to make sure.

Sounds like a bad crankshaft sensor.

SOURCE: 2002 Jeep Grand Cherokee Alternator Battery Problem

Regardless of what caused the smoke it is apparent that your alternator is not charging the battery.

Check the alternator is properly grounded, and that the B+ terminal is connected to the battery supply.
Check the exciter terminal (usually labeled "IND") is connected to the "BAT" indicator dashboard lamp - check the indicator lamp lights when the ignition is on without the motor running.
Battery terminal voltage should be approx 14.5V when the motor is running, with a load such as headlights on.
Check the fusible link ( or in line Maxi fuse) and their electrical connections is in good order.

The alternator/regulator may have been 'spiked' as a result of a poor electrical connection while changing batteries. The fact that the horn sounded indicates that a voltage spike had likely occurred.
I suggest you fix the battery charging problem first, then pursue whatever other problems that may still exist.

I was just driving my 1983 el camino and now it wont start back up all I hear is a click


Starter solenoid, low battery, bad battery connection, bad ground, failed starter, failed alternator. Start with the battery. How many volts do you read there with a meter? With the meter still on it, how many volts while someone else turns the key to "Start"?

Move down to the starter solenoid. How many volts there when someone tries to start? Move to the connection between the solenoid & the motor itself. How many volts? Put one meter probe on the BODY of the starter motor and the other meter probe on the negative POST of the battery. How many volts do you read when someone tries to start? Hint - you SHOULD read zero that way unless you have a bad ground connection from the battery to the block.

Why won't my 92 jeep start? Ihave a new battery and starter


maybe earth strap to chassis from engine. put a multi meter from battery neg to engine, set it to DC volts and crank the engine. should read 0 volts if ok. will read about 12 volts if earth is knackered.

Your alternator is regulated by the PCM. It could be the PCM or the ignition switch. Might want to try swapping out the shutdown relay just for grins before getting into the ignition switch. Good luck.

I have a 97 jeep wrangler, its a 2.5 liter 4cyl 5 speed. It has a starting issue now and again, it won't turn over lights and all electrical turns on but it just wont turn. When fuses are checked the start...


First thing you should do is check the starter draw. A simple way of doing that is to put a volt meter on the battery and crank the engine over. Volts should not drop below 9.5 while cranking.Since you replaced the starter, though some can be defective, the odds of getting a defective one with the identical problem you had before are slim. Therefore, it's more likely that you may have a bad ground. Check voltage between the positive terminal of the battery and the block (should read exact battery volts or just slightly less), then check draw again, with meter connected to battery and block. Readings should be identical to first draw test, or very close. Repeat, at the starter housing. If readings are low, clean the battery terminals and the engine end of the ground lead. Repeat testing and see if readings improve.
The reason you are doing this is that the starter draws more amps than any other item in the car. A bad ground can increase that draw above what the fuse can handle.
Biggest problem is that since it's intermittent, everything may look good when you test. "Blind" cure for that is to use a longer ground wire and attach the engine end to one of the starter bolts.
I also recommend that you check the starter relay (in the power distribution center) and any wiring associated with the ignition switch and that relay for grounding and good connections. Check under the dist center as well.

When the Jeep was new the volt meter read 14 volts....now the volt meter reads 13 volts with a one year old battery. Since the battery is a 12 volt battery should there be any concern that the volt meter...


It needs to be looked at,hook a volt meter to the battery,and start the engine,turn the ac on high blower,and the head lights on,the alternator should be putting out 13.65 volts to 14.25 volts,if it is any lower than this,replace the alternator,now,if the reading is not the same as in the vehicles volt meter,then the cables,positive and negative need to be replaced,the cables get old,and corrode on the inside and break down,they do not carry the current as they should.Shuold you decide to replace them,go with a larger diameter cable,both positive,and negative.

Will not charge


you will get some funny answers from some of these "experts " The symptoms suggest to me with out much doubt that the regulator is not doing its job correctly ,consistently.Iwould take it to an AUTO ELECTRICIAN and get it tested in situ.... there is only 4 things it can be , wireing ---battery---alternator-----regulator and of those the reg. is the only one that chops and changes. it will cost little for a sparky to check the reg ,. AND I WOULD LIKE TO KNOW THE OUTCOME

Jeep wrangler will not start have changed every sensor checked and changed fuel pump and bought new computer for nothing so changed out engine with one running now it wont start must be electrical need...


I'm assuming you checked voltage through the auto shutdown relay?
If you attempt to read codes, does it read? (even if it shows nothing except that it's working) Is there a factory security system? (if so make sure there isn't a broken wire in the door harness) Also, check block, dash and computer grounds as well as power from the ignition switch. Were there any problems with anything at all before it stopped starting?.

1999 jeep wrangler guages went crazy


Put a volt meter on the battery itself and take a reading when it is doing that. If charge rate is over 14v the alternator may be working but the output is not being cut down to "useful voltage" You may have a regulator problem.

Check engine light comes on after 2 miles of driving


Possible...Check output with a good digital volt/ohm meter. Hot, running, reading should change from between .1v to 1.0v. Take readings with sensor disconnected from the harness, using connector terminal as (+) side of connection and (-) of meter to ground. On multiple wire sensors, they have an internal heating element. this part goes to the two white wires. To test heater, connect ohm meter across both terminals and read resistance. The reading should show same continuity as if you took both meter leads and held them together. Sensor produces very low voltage and therefore any dirt or water in plug connector can throw readings way off. Make sure it is clean and dry.
