Alternator Installation

Post by Chuck W. » Mon Jan 12, 2009 4:15 pm

I thought some of you guys might be interested in the alternator installation that we do. This is a neat installation that tucks in under the blower and looks nice.

We use a Delco 10SI "one-wire" alternator that has been modified with a low-RPM cut-in regulator, so the alternator will charge at the lower RPM's that the the mule engine normally turns.

Here's the stock engine:
Image

First thing is to remove the belt guard and the blower cover:
Image

One thing that has to change is the oil drain line on the right rocker box:
Image

Here you can see the alternator mounting bracket and the new oil drain line. Couple of things to keep in mind, you may have to do a little "sheet metal work" on the shroud in order to screw the elbow into the rocker box, and BE CAREFUL, don't over tighten the elbow into the rocker box, it is very easy to crack the housing and cause an oil leak. This is just a drain line, there is no pressure, so snug is fine.
Image
Image

Once the alternator is mounted and the belt installed, you'll see that the lip on the blower will need to be modified.
Image

I used a cut-off disk in my 4 1/2" grinder to cut the lip back.
Image

Here you can see the complete installation, I like the way the alternator tucks in under the blower and uses the same drive belt, no need for the double crank pully. Some people mount the adjusting bracket to the engine guard, but I make a bracket that ties back to the bottom of the bed.
Image

The belt and blower guards complete the installation. I cut just a little off the bottom corner of the belt guard to clear the belt. You want to keep the belt guard because it has the timing marks.
Image

Here's what makes this so nice, it's a true "one-wire" installation, this single wire ties into the electrical system, either at the positive battery terminal at the starter, or to the positive terminal at the battery. Wherever you tie it in, be sure to install a 30 amp in-line fuse.
Image

Here's the complete installation. Very clean and works great.

Hope this helps.

I thought that it was a nice set up, but I don't know much about the different ways of doing it. If you look right above the tire there is a bracket and I do no know what it is for.

Just a note, these photos are for reference only, due to health issues, I no longer make the alternator bracket or do the install. Thanks

Major519, I am negotiating to purchase a mule which includes "some of the parts to add an alternator". I'm not sure what I'll need, but how do I contact you once i figure it out.

Check with John Emery, he may still have some of Bill Watson's reproductions and/or may be reproducing them himself.
