Is the wire running from the Alternator to the battery still available?

[hudskit]

I cannot find the parts number and I think that's the cause of my newest problem. The battery light comes on occasionally - simultaneously the voltmeter drops down to below 14 - guessing 13.8 or so - while the battery red light is on - and then I hit a pothole and the red battery light turns off while at the same time the voltmeter pops back up to a little under 15v - had it on the oscilloscope and everything checks out so it's got to be that set of wires in my mind . I already replaced the clip end that goes into the alternator - so it has to be somewhere in the rest of the line.... unless some has a better idea?

Sounds like a loose and or dirty connection.

I agree with fbm, but if you need that harness I have one.

[fastblackmerc]

Make sure the grounds are clean and tight.

Can can make a cable for you out of 4 gauge wire and copper terminals.

Thanks for all the help, guys - but could someone suggest which ground locations to check? I figure it will be easier to find the correct ones to remove , clean and reconnect if I could get a little help on where to look....

Thanks a million , guys - and thanks Fat Bastid for the new( er) harness!

All the grounds in the engine compartment.

@ the OP: that line from the alternator to the battery stud on the BJB isn't just a piece of wire. It also has 2 #12 fusible links in parallel with each other, in series with the #6 red wire. DON'T replace it with just plain wire.

any body have a list or pix of all the grounds on these cars? (underhood , etc) 2003 wiring manual is not as helpful as I might like. Here's the battery harness , at least shows you where two of them are.

Thank you very much for this - like you I have found that the manual is not all that helpful . When I had my troubles with the dome light not turning off it took me days to trace it back to a bad ground in the right rear door, of all places- which when cleaned up and reattached solved that particular trouble for me.

Are there any more grounds that should be checked/serviced in the engine compartment area?

[fastblackmerc]

Grounds are on the passenger side fender by the battery, on the front of the engine block and the top of the passenger side cam cover to the firewall.

HINT: look for the NEGATIVE - BLACK wire from the battery.

Thanks- since I'm replacing that wire I will definitely hit those 3 -Thanks!
