You are talking about the alternator plug, not the rvc sensor right?

Because, I thought it was odd that the bacon612's alt defaulted to 13.6V..
which is the stock initialization duty cycle of 58%=13.6V
But I thought the alternator needed that signal really..

the 2 pin connector on alternator has to be connected or it does not nothing but spin, at that point you are running off of battery power alone.
no IF's Or's about it. (a 2 pin alternator is activated via pcm signal)
the RVC sensor can be disconnected, this puts the charging system in Default.
it clearly states this is in the factory service manual.
if you have the rvc disconnected and the voltage is dropping under 12v at the battery post's then the alternator is not working, MAYBE a really bad battery but if the battery was eating that much voltage then there would be a short and it would get hot, wires would be warm or something sucking down that many ohms basically a really bad ground be it internal/external

Yea, that's what I thought too, but according to bacon, his acted differently somehow..
solli5packs acted like I would have expected.
