I have another picture of my sisters alternator readings off her dodge ram 2013 3.6l
The one that is far more spiked is mine. Hers is consistent, mine is wild. I’ve changed spark plugs. Crankshaft sensor, camsensor, throttle body, transmission TCC solenoid, fluid, filter
Alternator slightly whines and seens to be a bit erratic, those fluctuations could be felt when those injectors are firing off thousands of times per minute no?
