Re: 89 GMC Cummins conversion
 

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. :metal:

Re: 89 GMC Cummins conversion
 

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.

Re: 89 GMC Cummins conversion
 

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.

Re: 89 GMC Cummins conversion
 

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

Re: 89 GMC Cummins conversion
 

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??

Re: 89 GMC Cummins conversion
 

Those should look awesome!

Re: 89 GMC Cummins conversion
 

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

Re: 89 GMC Cummins conversion
 

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

Re: 89 GMC Cummins conversion
 

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)

Re: 89 GMC Cummins conversion
 

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

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

Re: 89 GMC Cummins conversion
 

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

Re: 89 GMC Cummins conversion
 

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.

Re: 89 GMC Cummins conversion
 

Pretty sweet!

Re: 89 GMC Cummins conversion
 

Nice hole cutting!

Re: 89 GMC Cummins conversion
 

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 .

Re: 89 GMC Cummins conversion
 

I'd be careful how you word things. :lol: 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. :ito:

Re: 89 GMC Cummins conversion
 

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....

Re: 89 GMC Cummins conversion
 

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

Re: 89 GMC Cummins conversion
 

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 ...

Re: 89 GMC Cummins conversion
 

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.

Re: 89 GMC Cummins conversion
 

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...

Re: 89 GMC Cummins conversion
 

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...

Re: 89 GMC Cummins conversion
 

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.
