Default MP3 Player gets Disconnected

Friends,

My mp3 players ( Sony ) gets disconnected from power for a second and then gets back to normal, when
  • I turn of my m800 engine
  • I change from high beam to low beam and vice versa
The problem occurred for a week and vanished on its own. Now its back again. What can be the reason ?

Thanks..

Have your electricals checked immediately. there is a possibility that it is a regulator malfunction or something like that. Do you have a relay for your headlamps ??

. Check the alternator rectifier plate and regulator. Are you experiencing starting problems? Best way is to hook up a multimeter to the battery terminals when car is started and then switch headlights etc., and see for appreciable voltage drops.

I think it is more of a surge which your HU is cutting out. the battery also could get damaged if there is a surge. how long has this been happening ? how many kms have you driven after noticing this first ?

Agree with esteem lover about surge part. Get your alternator checked, or your battery too could be toast soon.

I think more than 1500 Kms. Moreover HU is working fine no matter how long you play. It happens only in the above two circumstances.

I asked the service guy about the problem. He said it can be wiring problem but did not mentioned alternator thing. Where can I locate alternator. Any physical ways to check it before visiting any other service station.

its best left to experts. electricals are very tricky. get it to a maruti authorised service centre.

Only thing you can check yourself is the alternator voltage.
connect the battery terminals to a multimeter set in "Voltage mode".
You should see something around 12V with engine off.
When engine is on you will see the voltage jumping to around 13.5 at revvs and around 12.9 at idle. If there are any wild fluctuations then the rectifier place is kaput.
If the steady voltage is below 12.5 at any time or jumps too high its your regulator.

If your service guy says wiring issue, let him tell you what wiring issue is there. You can go to a good installer to check the HU wiring.
