89 GMC Cummins conversion

[COS399]

So, I spent this weekend trying to figure out why my alternator wasn't charging my batteries. To make a long story short the problem was with the wire that originally came with the truck, and that I had marked as being the alternator wire before removing the original engine, was only putting out 3 volts to the alternator. After jumping from the battery straight to the field wire it started charging like it should.

The internal Voltage regulator that I picked up at Ken's was not intended to go into this style of alternator but could probably be made to work. Since I had a bearing going out in it any way I decided to order me up a 1st generator (120 amp) alternator to put in it. Of course the price difference between the two also made the decision easier. I am attaching pictures of the internal VR going into the 1st gen. alternator.

Thanks for those pics. Install looks easy enough too.

Nice work! The exhaust looks good.

Thanks guys. Well my wheels made it in, but the tire shop was having a hard time getting them mounted so I only picked up the two that were ready. The other two should be ready to be picked up tomorrow.

It will be interesting to see them on the truck. They kind of look like cooler versions of GM PY0s. Great job on the truck. If I had the time I would love to sell my Duramax and build my dream truck which would be similar to this. Ken and the folks at Autoworld seem to be a great bunch of people. My buddy put a 2nd gen Cummins in a 99 GMC crew cab using a kit from them and it worked great. Reasonably priced too.

I had the same thoughts as Les on your wheels. They should look pretty sweet on there for sure!

[COS399]

Thanks guys. I chose these wheels because of how they kind of resemble the GM wheels but in a larger size. I did have my other two wheels and tires picked up. I should have the charging issues fixed this week and then it is off to the alignment shop before I put the new sneakers on.

So MaxxD is your cheVETTE a diesel??

Those should look awesome!

The wheels look sweet! What brand and size are the wheels and tires?

No it wasn't. I need too update my sig since I sold it about a month ago to a guy who is going to do what I wanted to and drop a V8 in it. Or try anyways. It was a 2 door though. Of course they make a crappy car like that to not rust at all but every square body and 67-72 has cab corners and rocker panel issues unless you find one that has been kept in a barn it's whole life. Lol

Thanks guys. The wheels are Moto Metal 964 in a 18 x9 and the tires are Toyo A/Ts in a 285/75R18 (35 x 11.5)

Good News - I got my alternator charging the battery. I had a defective voltage regulator and I added an extra ground.

Time to schedule the alignment so that I can get the new sneakers on.

[COS399]

I forgot to mention that I also changed the alternator charging wire from the battery to the starter solenoid.

This weekend I got some little things done. Buttoned up some wiring underneath the hood, changed the fluid in both axles and drilled both front center caps for the locking hubs.

Pretty sweet!

Nice hole cutting!

I wish I could say my hole was a nice . I had to do the same thing in my early 70's gmc hubcaps. Didnt look as nice when I was finished as it did in my head .

I'd be careful how you word things. But I get what you're saying. It is hard to cut a nice big hole like that and not have it be out of center or look like a beaver got a hold of it.

[6BT 56]

Get your mind out of the gutter . Lol. This is a family joint. Id be lying if I didnt admitt to giggling to my self as I hit "post reply " Lol....

[COS399]

This is more entertaining than anything on the tube. lol Between this and the tractor video I'm still laughing.

Have you ever checked out that pirate 4X4 site ? Ive been over there a few times . You must have to pass some sort of anti social test before they let you post . Those guys hack at each other as if the other guy just ran over your dog , and not by accident . I'd never post my build there . I would likely go to bed crying every nite as everyone and there brother hacked my ride online . Much more civil here . Maby we should move the who has the nicer hole , hub cap that is , over to the driveline section . Under rear ends ? My Canadian humor cracks me up anyway ...

[gerfunken]

I'm still trying to figure a reply to Ryan's beaver comment. But I think you're correct that the quality of the hole should be figured out on a rear-end specific thread.

i like to trim my hole nice and clean, like i like my ... nevermind.

i have a infrequently updated build on my 715 and my k20 on pirate. they dont bother me much, but i generally avoid that site for the exact reason. i understand trying to steer people in the right direction, but when did it become a who is the biggest dickhead contest? and coming from me, the guy that everyone that knows me has called me a dickhead at a minimum of once...

You've got all the equipment to make perfect holes, every time... some of us are jealous, and others would love to watch your technique...

Alignment is scheduled for Monday. I was going to put the wheels on and post some pics but the weather hasn't been cooperating. Cold, wet and snowy up here.
