The battery keeps going dead overnight on my 416. The PO did not have the regulator hooked up when I got it and the battery never went dead but did get hot. I hooked it up after I painted it to save the paint from a hot battery. It worked fine for a month or so but now pulls the battery down unless I unplug the regulator. Have any of you used the aftermarket regulators? Is there something else I could be missing?

I haven't had that issue before! Not sure what to say!

In our Manuals Section has a good guide to troubleshooting, cleaning and adjusting the regulator. There are sets of points in those regulators that need to be polished and gapped. Good Luck, Rick
Try this http://gardentractor...-system-checks/ or the engine manual.

The 416 doesn't have that style of regulator. No starter/generator!

Sounds like simply a bad regulator/rectifier. Diodes prevent backflow of current when unit is shut off, so diodes are shot, plus the regulator part is likely charging full blast when running, causing the hot battery. I've never bought a new regulator, as I usually have one used off salvaged units. I also used to put in low bids on several on ebay & snagged some cheap but good regulators that way.

Disconnect the negative battery terminal and put a 12V test lamp from the battery negative to the negative terminal.
Battery negative terminal <--Test light--> battery negative lead.
Anh amp meter (with multiple settings) will work in this configuration if the current draw isn't enough to light the lamp.
Once the current draw is observed, start disconnecting things (re-connect if no change is seen) till it goes away. That will be the culprit.
I bet the regulator will be it.

All testing points to the regulator plus after having the regultor unhooked for three days the battery us still hot.
