Voltage drop at ballast resistor

Disconnecting that connector was something like disconnecting an air hose with quick connect fittings on it. If there's 60 psi in the tank, then there's 60 psi in the line. Doesnt matter if its a big line, or a long line. There is no pressure loss because nothings flowing.

It will get easier. Just start with the basics on volts and amps. That will help big time.
