Charger

[tittaz]

Yesterday I tried to connect my ELM 327 bluetooth works great with Torque for android, and then wanting to test and connect it with the PC with various programs type scantool etc., I connected the battery charger to 12v at the battery with the engine off, and I noticed that with the ignition switched off, the battery charger takes between 0 and 6 amp alternatively, the cio? type 2-3 seconds to 0, and 2-3 seconds on the 6 and cos? via. Not ? not that I skip something by connecting it even why? I would then like to do a reading of it in the obd when I will arrive? the mpps cable and I don't want to jump the battery or worse yet, to the control unit. The machine ? a Audi A4 2.0 TDI, 2005, and the charger I got at the supermarket

[tittaz]

No, tonight may I try you say that it could be the charger ? gone?

[dariuccio]

which brand

[Matty23p]

But you got a kind of an invert or just charge the battery for the pc??

[tittaz]

Only charge the battery does not invert Bosch battmax 6, 12v

[Driver]

But ? an electronic charger or classic? Why? if ? electronic it could be that, or exceeds, the power (battery too low), and then detaches, or and party.

[tittaz]

No ? a charger classic, let's cut to the chase what do you advise me to buy?

[asdone]

Throw them, connect a battery similar to (and charge) in parallel only when when you remap a? To avoid the problems of voltage fluctuations!
However, if the first to map the controls have a voltage above 12 v you are pretty quiet :)
Pi? what else I would worry about the power of the PC

tip always have powered the pc, especially in writing...disable antivirus....to change the power setting so does not happen, sopenzione of the computer, to have the battery over 12 v or put it sottocarica....I have never had problems..

[tittaz]

For the pc and the power supply of your pc is not c'? problem, another car battery to be connected in parallel do not have to? the voltage measured with the multimeter with the engine off marked 12,38 yesterday. For? the battery must have already? a couple of years, I would not take the risk to stay in the briefs of the canvas when rimappo why? good luck and blind but the bad luck sees us very well...

Also depends on the type of unit the reading and writing change you need to make a bit of experience ...also the type of programmer makes the difference. .

probably your battery charger ? limited to 6 A. if the battery ? download and requires of pi? it might be that he is detached in order not to overload themselves.
if ? cos? maybe in the instructions c'? written.
