Here's the back story. The car is in storage and every time I come home, it does not start. Usually security message is reason, I replaced battery 4 months ago. When I don't have the battery charger connected. Car is totally dead, nothing comes on. When I connected battery charger. Everything comes on. The DIS cycles through every message. There is a humming noise. If you can give me line item instructions, I can get to it immediately, in case you are not available. Thanks in advance

Hi, as with all electrical issues there is a protocal so to speak and it all starts with us knowing the voltage being delivered to the battery when engine is running. Every 12 volt car made has to have 14-15 volts showing at the battery when the engine is running. This will tell us if its charging ok because of all the electronics in the car, it is VERY specific to what voltage is required while running.

So, let me know the charging voltage.

If the voltage is good, then i would suspect what is called a parasitic draw that is draining the battery when it sits. There are certain computer modules that are supposed to "time out" after a specific amount of time. We will get into that if the charging system shows 14-15 volts.

I cannot start - so can't test when running

Hi, sorry i missed you. If it wont start connect the volt meter and see what the voltage is when you hold the key to start position. If it drops below about 10 volts, the battery will need charged or replaced. Then once it starts, it has to be charging 14-15 volts and if its not, replace the alternator.

Hi, I was able to start my car this AM and took it to the mechanic, since i did not hear from you. I even did the call option last night. So I am willing to pay the first $5.00 + $5.00 for your email responses. Since you did not provide a solution, I do not feel I should pay the $45.00 amount that is billed on my credit card. Thank you for your time
