I believe that my truck (1999 Nissan Frontier SE 3.6L) has a parasitic draw issue.
Was going through the fuse box checking voltage, the "Audio" 15A circuit had full voltage, which I believe is normal and okay as the circuit stays live to power the clock. But then the last fuse I check, 7.5A "Air Con" also had full voltage, so I switched over to DC Amps and it read 162mA being drawn.
I'm assuming that this circuit should not draw any amps with the vehicle off. If that is the case and this is parasitic draw, I'm also not sure how to move forward to get this issue fixed.
