Changing voltage regulator
 

I have a cub cadet 108. The voltage regulator went bad and I got a newer electronic style. The only problem is the terminal markings are different. The new one has I,a,s,f. I looked it up and I is for light, a is for battery+,f is for field, s is for stator. Has anyone hooked one of these up before? What wires go where?

How about posting the Brand Name and Model (or Part) Number of this new device.

I have a transpo f540, and a motorcraft gr540, which are the same regulator. They physically look different than stock style but i don't see why they wouldn't work. I realize I probably have to change the wiring a little but it should still work. I just need to know what wires go where.

The part you are referencing is designed for an "Alternator" while the original V/R is designed for a "Generator". Thus, this new part won't work on a Generator System.

Thanks. We've been trying to get it work for a while. Where's the cheapest place to get one that will work. Thanks

Give our sponsors up at the top of the page a call or email them. They might have a good used one or can set you up with a new one.

Since you reside in Hawaii, I have no idea what it costs for shipping.

Our sponsors would be more than willing to supply you with the correct V/R (IH-545130-R93).

You could try these "aftermarket" V/R from NAPA

Just be careful with 'aftermarket' parts, some are quality components, others are dumped off ships from China. Remember, they can't make cat food right. Would you trust your cub to them?:bigthink: Not trying to start one of my 'Buy American" rants, but just a friendly warning that "you really do get what you pay for".
