so you replaced it with wrong alt. how fun that.?
but what is wrong I bet is thjis
not doing step1.
S1: remove battery neg lug first.
s1a if not dont the you blew up the huge alternator main fuse
connected to the huge alternator stud wire. boom its blow up
and 100000 new alternators fail and there are more fuses too.
check them all ,skip none, that means too FUSEABLE LINKS
and do not
let clerks tell you what to do. they are
NOT TECHS.
find out what the truck needs first
even here is clear
sadly the SM tells this,. yup used 4 types of ALT here.
- Rear Terminal, External Regulator, External Fan Alternator
- Side Terminal, Internal Regulator, External Fan Alternator
- Leece-Neville 165 Ampere Alternator
- Integral Rear Mount Regulator, Internal Fan Alternator
lost the old OEM working (before) alternator I hope not. did you?
this is one schem./
Link "J) blow if battery lug not pulled first NEG lug.
has internal regulator here. no ECU override on 5.0
hard to find truth here, the books do not cover all 4 ways.
some ALTs are
born dead with charge lamp burned out.
so make sure it is not. (called self excitation path)
