92Pony 1 #1 Posted September 19, 2009 First question - what's the correct name for the piece with the three wires attached? Secondly, does it simply look like the previous owner installed a replacement without removing the original, (in the background - which I would presume must have been faulty)? I was nosing around the tractor today when I found this situation which had me wondering...... Wade Share this post Link to post Share on other sites
nylyon-(Admin) 7,120 #2 Posted September 19, 2009 That's the voltage regulator, looks like it was replaced with one that has a different bolt pattern so it was just put in where it could be. You could always hook up the original and see if it charges? Share this post Link to post Share on other sites
Save Old Iron 1,563 #3 Posted September 21, 2009 Wade, also consider on most systems , the back side of the regulator assembly is usually exposed to the forced air cooling from the flywheel, The fins on the flywheel will direct some cooling airflow over the regulator / rectifier assembly to assist in cooling it down when its providing a heavy charge current to the battery or supplying heavy current when the tractor's accessories are turned on. Take a look at the backside of the regulator - it probably has "fins" on it. The "fins" provide a larger metal surface area that allows more metal to dissipate heat faster. The regulator assembly is electronic - electronics hate heat. So mounting the new regulator out of this airflow may shorten its life. You may even find if you clean the terminals on the old regulator / rectifier and clean the section of the assembly that bolts to the engine shroud (establishing a good ground to the regulator), the old regulator may still be functional.

Thanks Chuck! I did not know that (the part about airflow in the stock install position). I did some cleaning yesterday (addressed in other similar post) but will look more closely at the regulator itself, and check its attachment point to the shroud giving that a cleaning as well.
