Volt meter reading low on 93 jeep wrangler


... 1993 Jeep Wrangler

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 reads 13 volts rather than 14 volts?


Generally the standard voltage should be 13.5 to 15.5 depending on the load that is being put on the vehicle and age of the battery an older battery may require more voltage to charge. Unless the voltage drops below 13 you are probably ok. ... 1996 Jeep Grand Cherokee

I have a 2000 jeep grand cherokee limited and just the other day I noticed that the volt meter is reading lower than it had been. The meter for as long as I can remember was reading 14 volts with the engine running. I've noticed that when I first start the car it reads 14volts but after driving about 10 minutes the reading drops to about 12 volts. Is this something that I should worry about? My owners manual says the normal range should be between 11 to 15 volts.

Voltage irregularity I have a 2000 wrangler 4L. Yesterday my volt gauge would peg all the way past 19 and then the whole cluster would intermittently go out (every gauge to zero) and then come back on again with the volt meter again pegged. I changed the alternator about a year ago. I hooked a meter up to the alternator output and it is reading about 18. Someone told me the voltage regulator is in the ECM however. Any ideas?


You posted car as 1998 and 2000. so you will get wrong answers.yah think?18v is illegal, bad meter or bad reg. (or reg inputs wrong)where the reg is located, we need hard facts.engine size. 4l>year car. (neb ... 1998 Jeep Wrangler

About 3 weeks ago we took a trip of around 300 miles with my 2000 Jeep Cherokee Sport 4.0. After about 100 miles, the check guages light came on and the volt(battery level) guage went to zero like it shut off. I stopped and shut off the car and restarted it and the volt meter started working again, but only reading about 12 volts instead of 14 or so where it usually is. We kept going and every time i shut the car off and restarted it, the guage would shut off at about 30 or 40 mph. The batte


Hi this sounds like the voltage regulator on the alternator, maybe you should get the alternator changed out as this really would be the logical thing to do, i am surprised the garage did not suggest this as that would be the normal course of action ... 1999 Jeep Grand Cherokee

I have a 98 Jeep Cherokee Classic. The volt meter is not reading anything, but the dash board and everything is working.(radio,wipers,etc) It stalled out and now won't start back. Sense then the meter's not worked. What would this be?

1997 jeep grand cherokee limited only stays crunk if foot is on the gas, and if the rpm meter gets low enough it acts like it wants to cut off. Once it cuts off, it won't crank back unless it is jumped an da gas is being pushd at da same time. But the battery meter reads just like normal.


I can give you something to try. Since the Jeep is a chrysler product, chrysler vehicle computers run off of the battery and in most cases at idle the alternater is not pushing a ramped charge. Try cleaning the battery terminals and see how it goes. ... 1993 Jeep Grand Cherokee
