Re: Check Engine Light Help please.
the scanner does get power from the 15amp cigar fuse. this goes to the power ports and to the DLC connector where you plug in the scanner to get the dtc.
the charging issue light may mean a short circuit.
this short could be the alternator diodes going.could also be the voltage regulator/brushes in the alternator as well.
my alternator failed with 100,ooomi on it . and my batteries last 7 yrs then I just change them . so what I am saying is these alternators are weak ! If the alternator is n/g buy a new alternator no rebuild crap.
autozone has lifetime alternator with the lifetime warrantee. new. that is what I got. 3yrs now still good. my regulator corroded .
new alternator has the updated regulator.
