My car is overcharging what could it be to caves it to overcharged,i am a disable veteran,need help?


Sounds like a faulty regulator rectifier on the alternator borrow a compatible alternator to test the charging system
It usually is cheaper to replace the whole alternator than have them repaired

Battery voltage is 14-18 V when engine is running


alternator test to see if the alternator is overcharging or wire harness problem do an easy test find the connector on the alt and while running with multimeter at battery check the voltage when unplugged and plugged sometimes by unpluging the alternator it releases the voltage meter build in the alt

I think it is overcharging 19.0v, what is correct rate?


Normal charging is 14.8v (high) and 13.1v (low) - 19v is very high. Voltage reg in alternator is bad.

My jeep is overcharging by the gauge


with a car that old its possible the gauge is off but to be sure you can go to autozone or pepboys im pretty sure they will test the charging system for free . or if you have a volt meter you can check it yourself it should be 14-14.8 with the car running anything higher than 14.8 is overcharging . if it is overcharging you will need an alternator for sure and if the battery is over 3 years old its best to replace that too so you dont break down in the near future because overcharging cooks the battery so whatever life it has left has been cut hope this helps

I replaced the battery 3 weeks ago and everything has been fine. My wife drove around everywhere on Friday. She did not drive the van yesterday. It is now Sunday night. My wife went out ot start her van...


Your alternator is going bad. It should only put out 13-14 volts and therefore is overcharging your battery. This causes your battery to get a dead cell. If you replace the alternator and battery, make sure you check the cables for any shorts.

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.

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.

Over charging


get a volt meter set it on dc scale start your engine .take meter hook it to battery it should be 13.5 to 14.5. it shouldnt go over 15. if it goes over 15 volts your alternator has a bad voltage regulator. take it back get you a new one.
