Question about JVC KD-SX840 CD Player

1 Answer

I have wired all the cables, and I checked for 12v , but when i turn the truck on , the lights of the stereo come on for a few seconds and it shuts down, if u press the display button, the stereo turns on again and u can see the time for also a few seconds and then it turns off again. If u press eject u get the cd out, it turns on and displays the eject message and then shuts down, same thing when laoding, it loads a cd , give u the message of loading, and after a few seconds it shuts down. I'm looking for anyhelp, wiring diagrams to the trucks wires, install manuals, etc, I'm fresh out of ideas. the stereo is a jvc kd-sx840, and te truck is a ford ranger 96, 4 cyl, please contact me @ jgonzalez0511@gmail.com

I hooked up my pioneer dehx8600bh car stereo everything works perfectly except when I turn my head lights on the stereo loses power and factory reset every thing


Not sure what kind of car you have but,,, just for the heck of it, when you turn on your lights , try turning your interior dimmer all the way up. If the radio works again, then you have it powered from the wrong wire in the dash. It needs to go to a constant hot (12V) and Accy/ignition (12V) and not to a lighting wire which would power the back lighting of a factory radio.

That's because the memory wire has not been connected to a permanent live supply.

There will be an ignition switched 12v supply and a memory wire. The first is yellow on many brands and the second is red, but you need to refer to your fitting manual to check or look directly at the wiring harness as the wires are often individually labelled.

Since they both take 12v some folks mistakenly think that they can just be piggy-backed to each other and feed from the same supply. They can, but only if it's to a permanent live feed but that then leaves the risk of the unit being left switched on when the car is parked and draining the battery.

TAKE IT OUT AND TRY IT ON A 12V BATERRY AND IF IT TURNS ON ITS GOOD AND IF IT DOESNT IS NOT GOOD. IF IT TURNS ON FOLLOW UR CONSTAN AND UR POWER WIRES AND SEE IF IT HAS A FUSE BOX IN THE BOAT/ CHECK THOSE FUSES. AND CHECK UR BOAT BATTERY TOO CAUSE IT COULD HAVE DIED WHEN TESTING THE STEREO TOO IT HAPPENS ALOT ON BOATS

Citroen Saxo CD Player will not play when engine running


The car stereo has 2 +12V inputs: the constant batt input and the key in one.
So actually the stereo is always connected to +12V, even in standby.
When you turn your key, the key in input also starts, thus starting your stereo instantly.
When you turn the ignition on, the key in input is switched off for a couple of seconds, so that all the power goes to starting your engine.
After that key in input should be back on - this is your problem here.

One possible solution would be to cut this wire out, and split the RED battery +12V cable so that it enters in the key in input as well. Check wiring diagrams!.

Test this with cables out (without reinstalling the whole thing back in) and if it works.......leave it and put everything back in.

Only downside is, you have to turn off the radio by hand when you exit your car - or you could lose all battery power !

Car stereo


Sounds like the remote wire on the stereo is either disconnected or connected to the battery +12V instead of the switched 12V (which is switched on/off by the ignition key). If the stereo turned off before and just recently it doesn't turn off with the key, I'd vote for a broken/disconnected wire.

Doesn't keep memory


DIKA, first step - check your stereo batt backup wire , you must connect that direct or continues voltage from accu. Don't switch this wire, you can check if your car in off position , this  wire must still have voltage +12v - +14v if no voltage check your fuse near batt backup wire. Why that wire must have voltage,that's because the voltage used for backup your stereo memori. OK good Try , Fixya and Don't forget to vote me, thank's
