What makes my voltage gauge read low when battery is good?
When the vehicle speed is above approximately 24 km/h (15 mph), the engine/generator RPM is high enough and the generator current (amperage) output is sufficient to supply the current (amperage) requirements of the vehicle as originally equipped and recharge the battery. 1.
What happens if you have an incorrect ignition code?
The chip in the key transmits a specific code, of which there are millions. If this code matches the ones programmed into the vehicle, engine starting is enabled. An incorrect key code, such as from an unprogrammed key or damaged key, would prevent engine starting. Code “confusion,” such as having multiple keys can also occur, preventing ignition.
Can a unworn key turn an ignition cylinder?
Or, an unworn key may not turn a worn ignition cylinder, as they haven’t “worn together.” How To Fix It: The best way to do this is to get a new lockset, with new keys and a new cylinder. You might consider getting a matched lockset that includes the door and trunk cylinders.
Why is my mobility scooter not reading the battery gauge correctly?
But vast majority of the time, it is because they are not reading the battery gauge correctly. The first problem is that they read the battery gauge while the scooter is moving. This is wrong, because the battery needle or light drops when the scooter is using power.
Why does the battery Guage drop to zero?
Once it drop it stays there until the truck is shut off and restarted. There’s a code P1682 battery charging voltage low. I’m assuming it’s either a bad connection on a problem in the PCM. Disconnected and re-connected the plugs on the PCM.
What should the battery gauge read when the engine is not running?
A fully charged battery should read about 12.5 volts when the key is in the ignition and turned partially, but the car’s engine is not running. Step 2 Look at the voltmeter while the engine is running. Readings of 14 to 14.5 volts on the gauge when as a good sign.
What does a negative battery reading mean on a car?
This means that the battery is fully charged and the charging system is providing the current. A negative reading (below zero) means the battery is providing current, and unless the problem is corrected, the battery will go dead.
When do dash lights come on and gauges drop to zero?
Dash lights came on and gauges dropped to zero gasoline w… When driving, occasionally all the dash lights will come on, but the gauges like gas, battery, and mileage, will all drop down to zero. Then my radio shuts off. Fortunately, the car keeps driving. All of this happened today, at a busy intersection, right before a stop light.
What would make my voltage drop from 14 to 11?
First I had the battery light flash in message center and voltage was at 14.7 and took to AutoZone and replaced battery. Light was off for one day then back on. Then next day voltage was at 14.7 and stopped and started back up and I noticed the volt meter went to 11 and stayed there.
Why is the voltage reading on my alternator going up?
While watching the voltmeter display, start wiggling wires at the back of the alternator, the battery, and the remote voltage regulator (if there is one). If the voltage reading on the meter display goes up while wiggling one of the wires, you’ve found a bad electrical wire or connection.
What causes the battery light to go out?
Click to expand… Many charging systems put the alternator energizer wire through the light bulb. When the alternator starts charging positive voltage is equal on both sides of the bulb filament and the light goes out.
Why does the battery gauge go back to 12 volts?
When your gauge read ~12volts and a new battery it went back to 15 volts, the old battery was overloading the alternator with an internal short. At one time I had a battery short bring it down to 9 volts and the computer went nuts. The engine back fired I just made it to a battery shop.
First I had the battery light flash in message center and voltage was at 14.7 and took to AutoZone and replaced battery. Light was off for one day then back on. Then next day voltage was at 14.7 and stopped and started back up and I noticed the volt meter went to 11 and stayed there.
What makes my car voltage gauge read low?
As a vehicle slows, engine/generator RPM slows and the current (amperage) output of the generator may not be sufficient to supply the loads, the vehicle system voltage will drop and the lights will dim. Dimming of the lights is an indication that current is being pulled from the battery.
What should the voltage be on my truck battery?
Mine does this with nothing additional running on the truck other than the radio and a/c. This morning the needle was about 1 volt below (13 volts) the middle mark (14 volts) on the gauge. I noticed it, turned the truck off, restarted the truck and the needle went about 1 volt above (15 volts) the middle mark of 14 volts.
How to test the battery and voltage regulator on a Harley?
Step 1. Check the voltage of the battery while it is disconnected from the bike using the multimeter. The volts should be no less than 12 volts.
When does the fuel gauge read full on a Harley?
Mine drops down to about a quarter almost immediately after filling it up. Spoke to the dealer (Mackie H-D in Oshawa ON) and he said he’s seen a few and as stated here already, it’s normally a sticky float. I’m bringing it in Friday for its first service and they’ll look at then.
How old is the battery on a Harley Davidson?
The lights came off and on again for maybe 10 miles and then went off the rest of the way home. Plenty of cranking power. Battery is two years old and always on the battery tender when not riding.
