Hi, thank you in advance. Pioneer DEH-P4200UB RUNS ON 14V, NOT 12?!?! HOW?! Where was it getting 14v even just with ACC on?

Was working great for years in 95 Grand Cherokee; Pulled and tried to use in my 5th wheel to replace ancient tape deck. After quintuple checking connections, ground, constant voltage, Red/Yellow/Black all hooked up properly, reset button behind face pressed, after a full day of research and fighting I finally saw on the label it says 14v; my whole system is outputting a little over 13 constant. I can't find that anything special was installed in the Jeep to increase voltage, what am I missing?! Again, thank you!

I think you will find there is something else wrong related to the setup of the radio or a fuse. The 14 V rating refers to the nominal maximum voltage common in car charging systems which is allowed by a correctly operating regulator in the alternator, and the normal operating voltage should be around 11 to 14 VDC. I think the problem may be related to the radio recognizing the faceplate which was removed and reinstalled, which is related to security checking in the device - check the manual carefully.

SOURCE: 99 jeep cherokee sport 4.0l 6cyl voltage will go to 19v

The problem sounds intermittent, if you put volt meter on the battery while it is at that 19volt mark/reading(on the gauge cluster) you will be able to see if it is true. If your alternator is really charging over 16volts the lights should be getting brighter then usual and/or they are burning out. Find out ASAP, if the alternator has a defective voltage regulator, it needs to be replaced. Prolong use will damage components.

SOURCE: jeep grand cherokee constant grinding noise, and

As weird as it may sound, i'd check the power steering fluid. An empty power steering fluid tank will make the power steering grind and make weird noises, and having it at full lock will worsen the noise and have no fluid to build pressure it might starting jumping the steering around a bit. If the power steering is OK then you will need to take the rear drums apart to check for any broken retainer springs preventing the pads from returning into place and it will keep braking and grinding. Could also just be some rust or a broken off metal part in the drum also, but either way you will need to take the drums off and inspect the springs, clips and pads to ensure everything is OK and nothing stays jammed into braking position. Also be sure to verify the rear brake cylinders in the drums, as it may also be them that don't return to the initial position and keep the brakes on.

SOURCE: 98 Jeep Grand Cherokee - will not start - starter

I also have a 98 Jeep Cherokee with the same problem. I know I probably need to replace the starter eventually but as of now I turn it to accessory only, pop it in neutral, then start it and it works every time when it wouldn't even try to turn over with it in park. Don't know why it works, but it does. Give it a try.

Ive a VW passat 99 1.6 petrol and the battery light on the dash is appearing and i am not sure whether its the battery needs changing or if its the alternator, I got a battery tester and comes up 12volts...

It should be charging at 14 to 14.5 volts when the car is running. SInce that's what you're getting, your alternator is good, and the battery is on it's way out.

I have a 2003 gmc envoy, it runs like a kitten til you turn the heat on and it doesn't want to run, has died on me twice,,turn heat off and she runs pretty, someone help!!!! I am so tired of this truck...

check the alternator, the drain from the heater may be blowing the alternator, you will need to check the voltage on idle the voltage should be around 14v with no power use bar for engine. if under this say around 12.19v or less then there is a fault with the charging circuit. if at any point in the engine speed is changed from idle the voltage will drop a bit from 14v to just under 14v with lights on and high beam it will be around 12.85v. if this does not solve or if you are undecided have some one rev engine and use the heater and check voltage at the same time should only drop by 4v max any more than that there is a fault with the charging system. any problems with heater motor will blow the fuse also check it has the right type fuse fitted and check that it is not over heating or changed shap for other fuse this can be a sign it is making a bigher drain on the wireing.

My stabilitrak light started going on. I replaced the battery. Today while driving my battery went from 14.6 volts down to 12.5 and then back up. What is going on?

stabilitrac is from balljoints prob on tire rods of sway bar and altonator runs at 14v and batt runs 12. for it to be dropping to 12 you need to run to auto zone n they can check your alt. or while its runnind take your batt post off batt n if it keeps running your alt is good and if it dies out rite away alt has to be changed

We change battery get a new but the red light go on no battery.thank you

hi this sounds like it will be your alternator if the light is still on after you have changed your battery, to test it source a volt meter, then with the engine idling connect to battery terminals it should read, 12 to 12.5v rev vehicle to 1000 rpm, it should then read 13.5 to 14v if not then this will be your problem the alternator is u/s...hope this helps

I'm trying to figure out how the rear window defroster works electronically.I have a 2002 Chev Trailblazer and on one tab of the defrost to the grid I have 14V DC and on the other tab 0V DC.Now when I go...

Most of the time the defroster doesn't work because the frail lines that go across the window get damaged.
On my Chrysler it was painted on the window, and I bought "paint" to repair them.
If yours is the in window type, your screwed.
If there is a break, across the break you'll read battery voltage - 12-14 volts.
From one connection to the other will also read 12-14 volts.
One "tab" has to be positive, and the other has to be negative.
Reading at just some point on the grid will not tell you anything.

How does the car start and run? If Ok, I would make sure the computer housing is properly grounded. Grounds are normally the problem when getting wacky readings.

I bet the car runs fine, Correct?

Not charging after new alternator and battery

Check the simple stuff first. Battery cables and the ground wires and cable ends. Check the back of the alternator with a volt meter and make sure that the alternator is putting out around 14v. If you have good voltage there, check it again at the positive side of the battery, again you should have around 14v. If you don't have 14v then your problem is the battery feed wire from the alternator to the battery.
