eurotec :

Hi, what can I help you with today?

Customer:

when the sign is on many consumers don't work at all. for example: the a/c doesn't work, the radio doesn't work either and many others also the power seats.

eurotec :

Hi, when you get that message it is an indication of low battery voltage.

eurotec :

The computer turns off unnecessary items to save the battery.

Customer:

no

eurotec :

You will need to have the battery and the charging system tested.

eurotec :

Are you still there?

Customer:

the problem is in the morning , after 10 min. work very well

eurotec :

That would go along with a weak battery.

eurotec :

As the car runs awhile the alternator recharges the battery.

eurotec :

It is probably losing a little charge overnight.

eurotec :

You need to have the battery tested and also have a test performed to see if anything is draining the battery overnight.

Customer:

do you think all i need to do is replace the battery ?

eurotec :

Yes, most likely a new battery will solve the problem.

eurotec :

Let me know if you need anything else.

eurotec :

Are you still there?

Customer:

okay i will test the battery. but wait the main battery or the small battery?

eurotec :

Both batteries should be checked but the main battery is the one that would give you the warning message.

Customer:

ok I will

Ok, let me know if you need anything else.
