did you remove parts to have them tested??
do you have 12v @ the alternator??
have you checked the fuses?under the hood(engine compartment)

[big white bufflo]

i have seen on this web of a maxi 175 amp fuse located somewhere but cant find it all fuse in the box under the hood check fine the alt was pulled and checked but its hard to get to its down deep in the wheel well im going back in tomarro to check for volt at the alt

[inafogg]

book says 175A mega fuse is under the hood in the fuse/relay box
also a 30a fuse

[big white bufflo]

did some volt check i have voltage at large post and with key on voltage at the red wire going to regulator not voltage at little green wire at regulator fyi maxi fuse is on the end of fuse box by radiator

[inafogg]

what is the voltage reading @ battery when engine is running
whats the volt read at battery engine off

Ok i have changed the alt and still no charge i have 12.28 v at batt and 12v at the alt i said i have the main wire and two wires going to the regulator a small green and a nother wire green has 0v the other wire has 12v at it the regulator has three terminals in its main connector but my connector only has two the center is not used. all fuses under hood and dash are good maxi fuse is good any ideas HELP

i have done some looking on autozone wire diagram i think the alts the auto parts have given me wont work because of the regulator wireing is diffrent from the two valve and four valve what do some of you think thanks

this one has me stumped looking at the wire diagram on autozone for two diffrent motors one take s three wires on the regulator the other has two am i not seeing something in this trouble i have looked at rock auto on diffret alts they all take the same alts i have 12+v at main terminal 12+v at the regulator terminal wy is this not charging HELP HELP

if you have 12v @ the alternator it maybe that it is the wrong alt.
take back the alt. & see if they will let you try the other one listed
you have a non flex fuel engine correct??
it sounds like they gave you the wrong one

ok did some looking at diagrams(and i'm not the best reading)but...you say

your other wire that you mention is orange/lt.blu correct??
if so you have 12v(org/lt blu)going in but 0v( Lt green/red) coming out
this is why i think they gave you wrong part 2 wire vs 3 wire regulator

i have looked at a couple of alts at the parts store none only have two terminals in the regulator assy im wondering if i moved the wires around i can get it working but i realy dont want to do thatim looking at two wire schematics from az one 1996 to 99 3.0 2valve and 1996to99 3.0 4 valve and im still thinking there is the right regulator out there for this car

[inafogg]

auto zone shows 2 differant alternators for those applications
where did you buy the alternator you replaced??

[big white bufflo]

there are two application 3.0 2valve and 3.0 double overhead cam i have the 3.0 DOHC
