My Jake 1450 has the old style finned regulator like this one:

I am thinking it is bad. Can I use one of the smaller types to replace it. This is a Kohler K321S with 15 amp stator.

I believe the replacement your looking for is 41-403-06

I sell those in quality aftermarket  for around $60

 

If your feeling adventurous Genuine Kohler ones are available for around $120

 

Have a pic of one of the "Smaller" regulators?

I just looked up that 41-403-06 and the wiring connections are different than what mine is. It has one above and one off to the side. Mine is flat AC-12V-AC.

Kenny. I had the old finned type on my Sears, 2 actually. I tried a 15 amp one like the newer compact style, burnt it up right quick. I am burning up 20 amps with my winch. 

Anyway, as long as you have the AC/B+ or 12V/ AC any type will work. Tractor don't care as long as you have the correct 3 prongs. I cut off my factory connector and just use male spades.

My 'draw' will be the electric lift. Not sure how many amps it will take as yet!

The three terminals in line are 10 amp, the other offset type are 15 amp. The 15 amp can be hooked up two different ways. This is in the older finned type regulators. Noel

Kenny & Marty, the style Kenny linked to looks similar to the one that burned out on you Marty.  These type are designed to drop & bolt into a cutout in the flywheel shroud so cooling air for the engine passes over the fins of the regulator.  If mounted anywhere without this air flow, they will get hot & burn out fast.

Thanks everyone. I'll do some testing on the current setup this weekend. It may just be a bad connection. One thing that I question is why have a 15 amp stator with only a 10 amp regulator/rectifier? Especially on a tractor with electric lift?

Good question Kenny. 

MY Sears had the big finned types, both were 20 amp. I tested with a 15 amp new style Kohler, but it was only a 15 amp and it was free, it didn't last long with my loads. 

When I replaced it I went with a 20 amp newer style.

 

Your probably right Daniel, it also doesn't help maxing it out during use  :(

Been out doing some testing. With the engine running, I'm getting 22V AC, battery voltage through the regulator. Hooked a 20 amp regulator off an Onan to the wiring and get 12.7 DCV. I think I need to change out the stator, which I happen to have one.

Got it apart, after breaking a puller smooth in two. Had to take out the gas tank, grille, & starter. Here's what I found:

Needless to say, the stator I have will not work here. Much bigger.

Here's the regulator:

Do you think cleaning some of the rust off will help any?

 

EDIT: This only a 10 AMP system. Why, on an Electric lift tractor, is beyond me!

Cleaning may help, I'm not sure though. Definitely the 10 amp.

 

Whats the other stator from? Looks a lot like the one I need  :thumbs:

The battery is what supplies the tractor with electricity, the charging circuit charges the battery.

The electric lift is not used all the time, continuously, so even if it draws more than 10 amps the battery supply's it. 

How many amps does the starter draw and where does it get it's power from? Same thing for the electric lift and other electric accessories.  

 

If the continuous amp draw is more than 10amp, then you will drain the battery for sure.

That's what I am afraid of, Doug. I think the actuator will draw about 20 amps as it is a heavy duty type. And I can only fit a GT battery in the Jake! But, the actuator will only be used to raise/lower the tiller, so may work okay!
