Been using the Torque app for awhile and I have been having electrical charging problems recently. Ended up being the alternator putting out to much voltage. Replaced both alternator and battery. On The torque app you have volts command module and volts obd adapter What is the difference? I get 2 different readings about a voltage difference, I want to monitor the alternator output. I am thinking the command module is the alternator and the adapter is the battery. |

Not sure what that means, i just want to know what my altenator and battery are doing. Quoted:

You don't need CAN bus logging. You need a $20 DMM. DMM=Digital MultiMeter. I'm having trouble logging into AllData from home, so I can't help with detailed information. I'd forget the app for diagnosing this anyway. You've got to start at the battery and see what voltage it has with the engine running. Should be 13.8 to 14.2. This will tell you that the alternator is charging in the proper voltage range. If you're reading is higher or lower will tell you where to go next. As far as what the app is showing you for voltage, it's hard to say. There is a lot of voltage readings when looking at scan tool data, and the names can be different from one tool manufacturer to the next. I've seen enough discrepancies in scan data, that I always verify the reading with a meter. |

Alternator was putting out 17+ volts and boiled the battery. So both haven been replaced. In my car i have a app radio that normally just listen to slacker or pandora thru and the youtube video while waiting to go in to work. I want to have my torque display up and getting real time info since my idiot gauge never went to high, it stayed in the normal area. |
| Okay, I get what you're wanting now. I'd be looking for a data PID labeled Ignition Voltage or something close to it. The next best would be to find a Voltage PID that changes from 12.xx volts with key on engine off, to roughly 13.8 volts with engine running. That should get you close enough for your purposes. |
