good friend you must have the sgte symbology bat, acc, onn, star
bat = direct voltage 12v
acc = accessory voltage here you get voltage by taking the first turn with the key
onn = ignition voltage here you get voltage by taking the second turn with the key
star = starting voltage here you get voltage when making the third turn with the key, when you release it you must return to remain in the onn position.
I hope you find it useful luck!
