Subject: Re: Please Help me somebody.....
Since I've just gone through a similar tale, let me help out a tad.
A. Even electrical geniuses need help figuring out problems like this one.
We normal handy types just use the old intuition method until we hit upon
2. The "squealing like crazy" belt is a clue, but only a partial clue.
Sure it could use tightening and whatnot, but that won't cure the lights.
iii. Your beating on the side of the truck and having a light come on is
the best clue. I would suspect a short in a ground wire, since the lights
are dimming in disparate locations, but they all could share a common
ground. Usually, the ground is traced back to some location where it's
bolted to the frame or the body, and it's usually all corroded in a truck
that's a few years old. If the fuse wasn't blown when you replaced it,
then that's ok, but if the fuse did blow, then there is a really serious
short somewhere in that ground wire, and it's probably in a connector that
is corroded. I had one replaced the other week that looked ok on the top,
visible side, but was completely burnt out on the other side, and the wires
were fused from one hot to the ground wire.
So, if you want to do this, I'd get under the bed, look for corroded ground
wires first, then concentrate on the connectors, there's plenty of them back
And sure, tighten or replace that belt on the alternator.

That does sound like a good setup, but my motor only puts out a little over
260 hp. So dual 3 inches would probably be a little much.

I looked at one of these conversion F-150s and I thought it looked very nice.

It was a Centurion Conversion.

Should run under $100 for both front and rear (if you have the extended
cab). Probably $50 for just the front. The fit is perfect. I leave
them in the winter and move them in and out in the summer depending on
the weather. A truck accessories store in your town should be able to

Just wondering if anyone out there has converted an F150 to a Big
Block. Any success or horror stories would be appreciated.
Lastly, has anyone had experience with the new Detroit locker made
for C clip type axles?

Subject: ADMIN: Request for articles
If you have a talent, have done an upgrade, engine swap,
performance enhancement, repair, added an alarm system,
etc.... whatever it is you can share your experience
with others via the web site.
I recently put an article on the web site describing
upgrading 67-72 Ford trucks to front disc brakes. Another
list member has submitted an article on Ford C6/NP205
transmission removal and re-installation which will soon
appear on the web site.
You'll get full credit for an article, I won't edit it and
you keep the copyright (there will be a copyright notice on
it). I can't offer financial gain because, frankly, the web
site ain't making money. We come out a little above the
break even point. I will, however, send you one of our window
I'm searching for experience with any Ford truck/van model,
any year and virtually any area (an article on changing
tires is probably not a good idea!). If you're interested,
let me know (kpayne mindspring.com) browse the conversion
guide on the web site to get a basic idea of the format.
The C6/NP205 guide has a similar format.

Yes it had a trailer light hookup at one time or another. The thing I don't is why did it not show these problems back in May
when I bought the truck?

When the truck is not running it all works perfect. If I start it up and turn those lights on, and let it run, it still works
fine. If I drive the truck, I can get about 1/4-/12 mile up the road till it starts pulling that crap on me again. I am
thinking maybe there is an over load in the system that is causing my alternator to work hard, thus making my belt squeal. The
belt only squeals when the lights are acting up! If it is running and the system is working fine, it does not squeal at all.

Why and how do glass packs reduce power and economy? I personally like the sound of them over a turbo or any other muffler.
Anybody ever attempt to put a farm tractor muffler on a car or truck? Those a really unrestricted.
