Lost all electrical power while driving?

Speakers get power from the amp if your system has one or from the radio , if the tweeters work it's not a fuse problem . You like listen to your stereo loud . Blew a channel in the radio or amp ?
Take it and have it checked for DTC'S - diagnostic trouble codes
DTC B1025 01: Audio Output 1 Left Front Circuit Short to Battery
DTC B1025 02: Audio Output 1 Left Front Circuit Short to Ground
DTC B1035 01: Audio Output 2 Right Front Circuit Short to Battery
DTC B1035 02: Audio Output 2 Right Front Circuit Short to Ground
DTC B1045 01: Audio Output 3 Left Rear Circuit Short to Battery
DTC B1045 02: Audio Output 3 Left Rear Circuit Short to Ground
DTC B1055 01: Audio Output 4 Right Rear Circuit Short to Battery
DTC B1055 02: Audio Output 4 Right Rear Circuit Short to Ground

Each of the audio output channel circuits (+) and (-), at the radio and audio amplifier (if equipped) have a DC bias voltage that is one half of the battery voltage. When using a DMM, each of the audio output channel circuits will measure approximately 6.5 V DC. The audio being played on the system is produced by a varying AC voltage that is centered around the DC bias voltage on the same circuit. The AC voltage is what causes the speaker cone to move and produce sound. This voltage will vary depending on what type of audio is being listened to, talk or music, and type of music, as well as the volume setting of the system. Low volume and talk settings will measure around 1V AC and less, where constant music may measure 3 V AC and slightly higher.
Do you know how to do DC voltage testing ?
Without Amplifier without UK6
Ignition OFF, disconnect the harness connector at the appropriate speaker.
Radio ON, test for 5.0-7.5 V between the signal circuit terminal A and ground.
? If less than the specified range, test the signal circuit for a short to ground or an open/high resistance. If the circuit tests normal, replace the radio.
? If greater than the specified range, test the signal circuit for a short to voltage. If the circuit tests normal, replace the radio.
Test for 5.0-7.5 V between the signal circuit terminal B and ground.
? If less than the specified range, test the signal circuit for a short to ground or an open/high resistance. If the circuit tests normal, replace the radio.
? If greater than the specified range, test the signal circuit for a short to voltage. If the circuit tests normal, replace the radio.
If all circuits test normal, replace the speaker.

IMO TWO DIFFERENT ISSUES
WITH FUSE OUT OF RADIO, IT SHOULD NOT BE THE PROBLEM

Ck your alternator output, should be between 13.8 and 14.2 volts, A bad alt will cause the battery to discharge when driving, Once voltage drops to a certain level (9.8 I think ) the ecm starts to shut down causing all kinds of strange problems, like running bad ,trans not shifting right, even the radio ! It happened to me in my 95 chev p/u

The battery may only be 3 1/2 years old, but the factory
batteries seem to fail early in life

Check to see if has at least 12.5 volts across the terminals

I think you lost the battery & then the computer module went down,
as you turned into the driveway

If you only have 12.2 volts, don't try and charge it,replace it

If it does start ,check voltage again with engine running
The alternator has to output over 14 volts to charge a 12 volt
battery.

Battery terminal ,on the positive part of the terminal you had partial power.Mainly a bad connection

Your alternator is out. Those are classic symptoms of alternating going out. The alternator recharges your electrical system and when it goes out a list of strange things go on inside the dash, and you won't be able to go very far on just a battery. I'm glad you at least made it home. But yes you will need a new alternator for sure. Please rate this response so I can get my ratings back up to 90% at least.

sound like faulty alternator voltage regulator. check alternator out put at battery with engine idling should be 13.5 - 14.5 volts at 2000 rpm if not lower you have faulty voltage regulator.also check alternator drive belt and check alternator for loose wires.besure turn off radio before disconnecting negative battery cable to keep from locking out radio losing code.

sounds like an electrical problem, check your alternator an battery tru a shop, if the gages go crazy is a sign of the computer trying to shut down componets because the lack of power or voltage

good luck!

While driving my 2006 pt c. All the warning lights come on, the dashboard needle gauges go down, and the car looses power. I pump the gas peddle and it goes back to normal.

is the altinator putting out voltage ?
