What condition is you're battery in as if that's on its way out you could experience the problem you're having. Just a thought.

SOURCE: Basslink keeps cutting off into protection!!

From what i have heard, If you have a speaker level input connection. this sympton does occur. You buy a scosche LOC and try giving the input to Basslink, it should work fine

SOURCE: alternator light on

The alternator is not producing any power . If it were the engine would run without the battery. Check the wiring on the alternator. It must ave an exciter wire to make it work.

SOURCE: replaced alternator and battery still showing low/varying voltage

It soundls like you have a high powered sound system and you might have to step up to a higher amp alternator, that will give you enough power. Your battery should be fine too. Try to find out if the voltage regulator is built into the alternator and if not ask to find out where it is on the car and replace that to.

SOURCE: alternator putting out 16.5volts

or and more likely... the voltage regulator either mounted on the alternator or on the wheel well is defective.

Why does the voltage drop to battry volts when i put the gear lever in drive?


the voltage should remain at 14.5 volts at all engine speeds above idle 13.9 volts at idle indicates that the alternator is charging but not at set voltage
head lights are the biggest drain that affects charge rate rate and it it maintains and from you description that is not a problem
when you select a gear it indicates a heavy drain which is a high resistance or a dead short in that circuit that is taking out more power than the alternator is charging
There there is nothing in the gear selection that draws such power
the other thing is that when selection a gear the engine rpm is tool low and the alternator stops charging
for auto vehicles , the idle rpm should be at 800-900 rpm dropping to 750-800 in drive

WHY IS MY VOLTAGE FLUCUATING CONSTANTLY FROM 9 VOLTS UP TO 15 VOLTS????


It sounds like a loose cable that is vibration sensitive. I am not exactly following you but if it stops when the car is turned off then get the alternator and or regulator tested. Your battery should hold about 13.8v when running.

89 Yamaha virago 750 while riding lights go dim and engine cuts out unless bike is revved up then engine runs and light come back (sometimes) what's the problem?


You have a charging fault, it sounds like 1 phase of your alternator is down , so giving a low charge rate check in this order.
alternator winding resistance at the plug/ skt into the regulator and,or reg/ rectifier unit
the plugs clean and connections good.
next the out put voltage which should be about 13-14 volts just above idle, lights off, rev engine up to 2-3 thousand revs voltage should be 14.5volts,turn on the lights voltage should not drop to under 13 volts with the engine above 2k rpm.
low charging rates are normally down to alternator and wiring issues not the regulator which if faulty wil give no out put , so no chage at all

How do i set the clock on pioneer deh2950mp receiver


I couldn't find your model. You can try the following procedure. It is common for most Pioneer decks:

  1. Press and hold the SOURCE button until the unit shuts off.
  2. Press and hold SOURCE again until the clock appears.
    *With some models you will press and hold the FUNCTION or AUDIO button instead of the SOURCE button.
  3. Press the left or right arrow to select the segment of time you wish to adjust.
  4. Press the up or down arrows to increase or decrease the numbers in the blinking segment.
  5. Once the clock is set correctly, press the SOURCE button to exit.

I have a Pioneer GM X862 car amp, with a constant red light on it. Also, it is supplying the subs with power, they are lightly vibrating but its not pushing like it should. No bass.


Make sure your power line comes directly from the battery and that iyt has no abrasions or cuts in it. Check your ground and make sure that it has a good connection to the vehicle chasis. Ensure that the remote line is connected properly to the remote lead from your head unit/receiver.

Common mistakes in this area are using the remote turn on lead as a power lead. It does not have near enough power to drive the amp so you will only get a slight trickle of power.

Good luck!

Hi , I just brought a KD-G646 head unit and it wont play cd's at all. The radio works fine, but the usb only works if the unit is turned down. Could i have something wired wrong or is the unit faulty. It...


well, the USB problem i cant help you with, but if the cd isnt loading, theres probably something wrong with the loading mechanism, which usually means that the unit is faulty. it would be more cost efficient to buy a new head unit than to pay someone for the parts and labor to repair the one you have.

SOUND CUTS OFF AT HIGH VOLUME AND POWER LIGHT FLASHED RED


You need to check the DC voltage across the power and ground terminals of the amp. If the voltage drops below ~11v when the amp shuts off, you need to check the power/ground wiring and fuses.

If the voltage remains above 11 volts, you may have a problem with the load on the amp (incorrect ohm load, shorted speaker, shorted speaker wires...).

Amp protection light comes on when raising volume...


It sounds like you either have too low of an ohm load or the voltage is dropping at the amplifier's power terminal.

With your multimeter set to DC volts, the black meter lead on the ground terminal of the amp and the head unit on (so the amp will have remote voltage applied), touch the red lead alternately to the B+ and remote terminals of the amp. If the voltage is below ~11 volts, you need to check the wiring feeding whichever line is too low.


If the voltage remains near or above 12v, disconnect one speaker and see if it shuts down. If it doesn't, disconnect that speaker and connect the other speaker. If it only shuts down with both speakers connected and the voltage is staying above 12v, the ohm load is probably too low and you'll need to rewire the speakers.

No sound from the amp


With your multimeter set to DC volts and the black meter lead on the ground terminal of the amp, touch the red lead alternately to the B+ and remote terminals. If the voltage drops below ~11 volts, you need to check the wiring feeding whichever line is dropping too low.


If the voltage remains near or above 12v, disconnect all speaker wires and signal cables from the amp. If it powers up and the light stays on, the wiring needs to be checked. If it still shuts down, the amp likely has at least 1 blown output IC.
