ok guys thers the infor model:195702 cod:96040418 type:012801495623

now i have taken the alt or stator (4 amp dc olny with original connector that has diode or resistor in it) off another 8 hp briggs for this type of engine and installed it and the flywheel from it on this engine now there is four holes on this block that i notice i used two of them and cannot remeber if the other 2 were equal to these now i have seen the ac type that require a regulator and they have the four hole mount and was wondering if i could double up o the 4 amp dc olny alt or stator i cant remember if the holes were equal or not

im asking this because of the electrical system i have on it is large 2 fog lights turn siganals and brake lights with trailer hook up and i want the power cuse my 85 amp alt setup isnt workin out this would be an easy temp fix

this is all on my john deere R-72

IF I understand what you are saying, the four mounting holes for alternator stator are equally spaced.

Alternators have diodes in them to convert AC to DC, no resistors, they do another job. Don't know about what I think you suggest, never tried it.

I am a bit confused. Are you trying to double up stators, or use a bigger one? You kind of have a lot of typos and it is making it hard to figure out what you are saying. What do you mean by the holes being equal? Your electrical load does not sound too high, just lights. How many watts are you talking about? Remember Volts (E) x Amps (I) = Watts (P). So if you have a 12 V system with say a 10 A fuse (limit of your system) that would be 120 W. Are you trying to run halogens or something?

Doubleing up stators would be a neet idea... So Be the first to try it and let use know how it works... As long as one does not try to backfeed to the other it might work... A diode on each unit would stop the backfeed...

yes im trying to double up stators my lights are 55 w fog lights so the 4 amps just aint enough to keep up lol i want to at least get close to the amperage required eventhough i have a truck battery on it i want to maintain the charge if i can vice taking alot out of it at night when i do use the lights even though this rarely happens as i have all day to do stuff but this may change in the future i did rebmeber that i have an old block thats bare bones so i can try the set up on this and check clearences before doing it ot my running motor thanx for the input guys and more is welcomed also i do plan on useing the factory diodes in the conector the little plastic clip with the red ends

So you are going to stack the stators? Do you have two sets of magnets also? What about the clearance in the flywheel, will it hold all that? Maybe you could just use a single bigger set up. For instance I have a 10 system in my tractor, but I am pretty sure the 20 amp would fit. Would you then feed the battery separately from each or try to tie them together? Maybe I am just not seeing what you are and I'm making too much of it.

heres the deal the big 10 amp one is a ac unit requries voltage regulator it is a continuis circle with four mounting point i have the 4 amp strait dc output one it is a 1/3 circle with two mounting points was wonderig if i can use the other two holes for another stator

OHHHHHHHH....... Well that makes so much more sense. Ok so let me ask another dumb question, why not just use the 10 amp, and use some rectifier diodes to charge the battery? That's all that "voltage regulator" does. It's all mine does anyway.

AHA! Now the picture is complete. I assume the 4 amp stators are acted on by magnets in the flywheel? If so the orientation of the second stator may be an issue as far as it making straight DC. It might make a signal 180 out from the first one.

Ok so, the orientation should remain the same, my thoughts would be to hook them up and then check each output to GND. If they look good, I'm thinking I might run each separately to charge the batt. What were you thinking?

I would use a diode on each one.
Then join the 2 wires to 1 AFTER it has passed the diode.
That will isolate them from each other and should prevent them from "fighting against each other" in case the phase is out of sync.
