1 Answer

Check gauge/low voltage

2006 dodge 3500 5.9l diesel. Dash voltmeter is reading around 11 or 12, and check gauge light comes on. I charged batteries good and drove it and about 15 miles later check gauge light back on and low voltage. No codes coming up. I've checked batteries and all my connections. How can I tell if its the ecm? Shouldn't it throw a code?

May or may not throw a code, have you had the alternator checked, this sounds like a bad alternator and also you charged the batteries but have them tested also, this sounds like an alternator problem.

SOURCE: 2002 Dodge Ram 1500 ,4.7L V-8 Battery is not CHarging

A lot of Chrysler products have the voltage regulator in the computer. I would check the charging system wiring first for poor connections and if nothing else is found there is nothing else for you to do but change it.

SOURCE: LOW OIL LIGHT

well when oil is cold its thicker
as the vehicle heats up the oil becomes thinner in the oil pan
in which when the vehicle reaches core temp the oil pump doesnt need to work as hard

heres some other areas to look at
bad oil sending unit
in the pan the oil pick up pump filter needs replacement
oil filter clogged
bad oil sensor
vacume leak
these things need to look for and adjust or replace
the oil pick up pump in pan needs to be serviced by service tech at the dealers this is something a do it yourselfer could not do on own with out proper tools

My battery gauge goes out and my check gauges light comes on and battery doesnt charge in my 2002 dodge ram 1500 slt with 5.9 motor


with the engine running use a volt meter to check battery voltage with the head lights on, should be around 14 volts on a 12 volt system, if 12 volts or less the regulator or alternator is at fault . if around 14 volts there is a drain or short, the battery could also be faulty.

Code active, unplug coolant sensor dash gauge stops reading


What make vehicle ? some vehicles have two coolant sensors . One for temp. gauge an another one for the ECM / PCM input. Do you have a check engine light lit ?

A DTC will be set if an abnormal reading occurs, P0116 for sensor performance, P0117 low input or

P0118 for a high input. The coolant temperature sensor temperature reading should closely match the

air charge/manifold temperature reading on a scan tool if the engine has not been run for over an hour.
The sensor circuit can be checked for proper voltage using a voltmeter.

1978 chev k10 alternator output 14.4 on bench, reads 9 amps on truck gauge 12.2 on ampmeter at battery with truck running why


amps reading on the truck amp meter is the current that is being generated to run everything as well as charge a battery that will be at best around 80% charged.bench testing an alternator gives these readings as the regulator is feeding into fully charged batteries with no draw on the system. When batteries are 100% charged the charge rate will be as low as 2 amps but in a car where there is a current draw for the ECM , ignition , fuel pump and what ever the alternator feeds these first before it charges a battery. You used a amp meter to get a voltage reading which is reading the voltage drop across the current draw. If you had used a voltmeter (multimeter) then you would see a voltage increase with the rpm increase. The

Volt gauge reading low but still charging 14.2 volts


the low charge # @ gauge could be caused by bad ground or high resistence in the wireing harness. Don't think it has anything to do with your 4x shifting prob I would check 4x switch and electric motor on transfere case.

2003 mazda tribute, occasionally won't start. fuel pump replaced about 1 month ago. bad starter?


Many batteries may only last around three years. Check battery voltage at rest before starting. Any voltage in the low 12v range may be a sign of a faulty battery.If low voltage present, then perform a parasitic drain test:1) Disconnect battery POSITIVE terminal and connect ammeter in series, between battery positive terminal and positive lead.
DO NOT START THE VEHICLE!!

2) With all vehicle doors closed, alarm off, lights off, radio off, and all other accessories off, wait for around 20 minutes and then read the ammeter. A healthy system should read about 0.03 amps and little more. If reading more, then the vehicle could be suffering a parasitic amp drain, and you will need to locate this issue.


3) Reconnect battery when finished.


If no major parasitic drain present, yet low battery voltage then:


4) With vehicle started, check the voltage charge from the alternator. Connect voltmeter to battery terminals and take reading. A healthy system should be charging in the range of 14volts or down to around 13.5 volts. If reading around 12 volts only, then check and replace alternator.

Remove and clean both battery terminals, then reinstall making sure they are both tight. Also check the battery voltage with a voltmeter (it should read 12 volts minimum) or better yet take it to get it tested. The battery may need to be replaced.

Check lights


It could be from a few issues. It definitely has to do with either the generator not working properly (recharging the battery, or a faulty battery not holding a charge. If you happen to have a voltmeter, you can test the battery voltage before you start the truck (should be about 12 volts), then test it while the truck is running (should be reading around 14 volts) this will mean the generator is charging the battery. Most batteries last about 3-5 years on average. If the voltage is not above 12 volts when the truck is running, the generator is bad, and you could get stuck with a dead battery.
