17GTH-L Repower (electrial questions)

[Chris727]

Hi Guys. The 16HP CI (32000 series) briggs engine I am going to install on my 17GTH-L(7117) has a DC only stator on it because it came on a Yazoo. My question is which kind of stator do I need to buy for it? Tri-Circut, Dual?, Regulated? There are something like 4 differnet kinds. I am not using a starter generator on this machine and it will basically be the same as a 7116H. Thanks! Chris

Stator is paired with the flywheel. How many amps DC? I beleive parts book says to check the service manual. What are all the numbers?

[Chris727]

So would I need a flywheel too? I looked in the large frame service manual but I couldn't find any info as to what amps etc. system the tractor has. I'm really not an electrically oriented person. The engine #s are Model #326437 Type# 0318-01. I will need the same stator the 7116H uses, but what kind is that? Thanks Chris

I think Al could shed some light on your problem. As for myself I have never heard of a DC only stator. If it charged on a Yazoo it should charge on anything else. Just my two cents. Stan

[ambler]

you get the 32400 parts manual use the type no. to find your flywheel, then refer to service manual. flywheel has fixed no magnets it limits a stator output. If it puts out 12 volt you need hou will it charge a battery.

HI, If it charged your Yazoo it should work on the 7117. If you can look and tell me the color of the wires coming out of the stator and describe the plug on the wires including the plug color, I can check a chart I have in the shop and tell you what charging system you have. Will watch for your post on this. One of our Uni-kits will convert the tractor from a battery ignition engine to a magneto ignition engine. It only requires hooking up 4 wires and you do not have to mess with changing the igntion switch and having to mess with any safety switch wiring. Al Eden

Hi Al, I never had the yazoo that the engine came off of, I'm only assuming the stator worked. There is one red wire that I see with a round plug. The briggs service manual identifies this as a DC-only. It is descibed as follows: -3 amps DC+ for charging battery -One RED lead from stator -Diode encased at connector -Red connector output lead In the briggs parts manual it lists my type # (0318) as having the same flywheel as the first two type#s used on the 7116. The 7116 used several different type #'s. #0315 (1979-1980) #0333 (1981-1983) and #649 (1984-1989). So based on that I assumed my flywheel was right, just the wrong stator for my application. I have been told that the DC only Stator will only charge the battery and doesn't have the capability to handle accessories such as my headlights, or an electric clutch. I would also like to keep using the safety interlocks on this tractor. Al, How much is one of the Uni-Kits? Does it just replace the old kohler wires? Thank You! Chris

Chris, It appears you have the 3 amp charging system. It probably won't handle headlights if they are used alot. I didn't get your stator part #s yet I was short one person all week and another Thurs and Fri. All of my plans didn't happen. Will try to get your info tomorrow. If you are buying a stator, I would buy the high amp one with the regulator. Will get you numbers. Some of the high amp systems have flywheels that have larger magnets in them, but I need to check if this true of the 326 family. The UNI-KITS part number 80-0001-001 is 29.95. It is used for 3 different applications. 1: Convert battery igniton tractors to magneto igntion engines. If you get it you have 4 wires to connect and the tractor thinks it has a battery ignition in it yet. You don't have to change anything in the safety switches or the igniton switch. 2:It is also used to fix the problems with the solenoid actuated starters used in Kohler Commands, Some Briggs Vangards and Many Onan applications. 3: It can be used to switch high current applications up to 40 amps using a tiny switch less than 1/10th of an amp to control it. Will get back to you soon, Al Eden

Chris, If you want to spend the money, the 696458 stator and the 691185 regulator rectifier and a 692306 wire assy will give you a 10 through 16 amp charging system depending on the size of the magnets in the flywheel. This would be the best if you want to run some lights etc. It is also the most costly. You could use the dual circuit system and you would have a low amp DC output and an AC output that you can run the lights from. With these, the lights are usually dim at low speed and not all that bright at high speed. However the stator would be in the same price range, but you would not have to buy the regulator only a matching cable to connect it. I would go with the regulated system, or use what you have. What you have wouldn't keep up with lights, but if the lights were only occaasionaly used would probably get by, though if the lights were used for a while and you shut the tractor off, you might not have enough battery left to restart it unless it ran for a while with the lights off to bring the battery up.

My 808 originall had the 8hp with the AC and DC coils. When i put in the 18hp Briggs that only had 1 wire out. DC only. I rewired the lights to be swithched off the battery rahter than run from the AC windings that shoulda been there. That way the battery is being charged and im able to use the lights with out it running(but i have yet to find out HOW long!)

[Chris727]

Thanks for the info! Sounds much more expensive than I was hoping. I thought I could just buy the right stator for around $25 and be done with it. Starting to think this project wasn't worth taking on. If I found a used wiring harness off a 7116H, could I just get the stator and skip the regulator? Thanks. Chris

[Al]

Chris, I think you can use a stator out of an old junk aluminum block engine etc. I think the stators are all common. Hope this helps. Al

[Chris727]

I found a deal for around $50 instead of the $70 on the rectifier, a friend can get it in cheaper on his spring order from Briggs, but I'm still not sure what to do as its still more than I wanted to spend. I know I'll need the regulator/rectifier. Maybe I even have a stator somewhere on an aluminum twin. On the other hand I could buy another starter/generator bracket, and set it up with a spare starter generator I've got. I suppose the S/G would give ample power supply for accessories. Thanks for the suggestions!
