Voltage Regulator? Diagnose Me. - Toyota Yaris Forums

Alright so this has happened 3 times so far.

Ill be driving and randomly the Headunit/AEM Volt gauge will turn off and the Dash P/S Light will come on for a few seconds and then turn back off/on.

Sorta scary, also I've noticed that the voltage will just seemingly randomly shoot up to the high 17's low 18's until I turn off the car and restart it.

Today however when trying to leaving a job site for work the car would turn on and everything but the P/S Light on the dash came on, the car would not shift out of park, the Voltage gauge showed nothing (not even 0volts) and the Head unit would not turn on, I removed the positive lead on the battery for a few seconds and reattached it and this fixed the problem...for now.

Thoughts?
