alternator red wire
I'm about to replace my alternator. The main red wire off the back of the alternator is quite blackened from age and heat at the crimped connection.
My guess is if the terminal is ugly, probably the whole wire is ugly. What's involved in running a new red wire?
Any ideas.
Thanks

I've been poking around. Followed the wire along the top side of the valve cover then it falls off the edge of the earth down behind the engine. Can't see a GD thing.
I'm going to pull the left front wheel, lower fender and the battery. Maybe I'll be able to get in closer.

I just caught sight id several fusible link down under the "jump start box" I believe you kids called it.
It tried Lordco to get a F.L. but they seem to think it is a dealer item. I'll find one!
Thanks for the replies.

I'm not familiar with LORDCO so I can't help there but it's NOT a dealer item.
If you're doing 6AWG instead of the 8AWG you want a 10GA FL, if you're doing 8AWG wire you want a 12GA FL. FL's are explained very well here and that may prepare you for more effective shopping:

I don't buy from White but their information is excellent. A Ford dealer might have links with rings already attached to them on the shelf. Ford went through links like crazy for some reason, I believe it might have had something to do with their older remote solenoid usage for starter motors.

I agree with WVZR - crimp then solder everything - then use heat shrink. Use the good heat shrink, some of the stuff they sell at discount stores is pretty light duty. Some heat shrink has a sealer on the inside - it works quite well in preventing moisture and other contaminants from getting in.

[QUOTE=WVZR-1;1587432915] Don't know the year but it likely goes to the battery jump block and it needs a fusible link there. OE wire is 8 metric (8-AWG) so I'd consider 6-AWG and the proper fusible link. \QUOTE]
when you say jump block, do you mean that thing behind the battery that all of the power wires go to? It looks like a distribution block? If not, where is the jump block located?
I'm replacing my alternator today and might as well replace this wire as well.
Good info guys.

I did not replace the post on the alternator. Actually one of my buddies has an extra off his car sitting in his garage that I'm driving over to pickup in a few minutes. He said it appears to be pretty new so I thought I'd give that a try since it sounds pretty easy to install. I will have to compare the pulley sizes however.
Thanks for the clarification. I'm going to hunt down that fusible link from the battery to that jump start block later today as well. I may replace the pos cable too but I need to see if it's available locally.
