How can I find the 12 volt source in my car?
head-unit To find the accessory source, start by ensuring that the ignition switch is in the “off” position. Insert the positive probe in any connection (except the constant 12v source). With the ignition switch in the off position, you should not read any voltage on the multi-meter. The next step will be to turn the key to the accessory position.
When to use a 12 volt ignition source?
When a car is running (engine on) the ignition (on) source is live (supplying 12v). however use ignition switched power when the car is not running but the key is in the ignition (on) position. The ignition (on) source should be used when dealing with high-current applications which include some of the following:
Should my car be running when I use a 12V DC power?
So the correct answer for this question is Yes your car should be running when using your power inverter except for short duration situations. Yes , I am sure the car needs to be running and re charging the battery through the generator while you use the 12volt dc inverter or the battery will die down fast.
Where can I find a constant 12 volt source?
Typical applications for a constant 12v source include some of the following: alarm system remote starter clock etc .. To find a constant 12v source, you will use the positive probe (typically red) of your multi-meter.

Why does the voltage drop when the key is in the Accessory position?
If the voltage drops to zero when in the accessory position, then back to 12v when the key is in the ignition position, you have found the ignition source. If you do not read 12v (approx.) on the multi-meter when the key is in the ignition (on) position, this indicates that you must have selected either the the cranking source.
Can a 12 volt source be read on a multi meter?
With the ignition switch in the off position, you should not read any voltage on the multi-meter. The next step will be to turn the key to the ignition (on) position. If you have selected the proper source, you will now read a positive voltage source (approximately 12v).
