LX279 not charging

I'm trying to help a good friend that has an LX279. I am familiar with 316/318's but not the newer LX279. His battery doesn't seem to be charging and the dash "discharge light" is on all the time. I know the "discharge light" simply means not enough voltage to provide charging and could indicate non functioning stator, voltage regulator, poor connections, or shorted safety switches.

He recharges his battery after every 3 or 4 mowings to get it charged up so he can use the tractor again. I checked his battery with a meter, shows 12.4 volts. With tractor running shows 11.8 volts. I assume the LX279 with Kawasaki engine uses a stator like the 318 Onan to generate charging voltage. Is there a voltage regulator like the 318 to check output from the stator at? I didn't see anything that looked like the 3 terminal voltage regulator on an Onan engine. What and where should I be looking on the Kawasaki engine or LX279?

Pull the plug and see it you are getting a/c voltage off the stator..... Think it should b around 30 volts ..... If so, plug that back in and see if you are getting 14 volts off the regulator... If so there may b a bad wire somewhere

Plug off the stator...those wires should lead you straight to the regulator

I would have to look at my lx tomorrow to b sure .. But I don't think those wires would b inaccessible... The plugs are most likely out in the open

On the LX178 the VR is on the back side (rh) of the dash tower. On the GX345 its on the RH lower side of the dash tower. Finned cast aluminum housing about 3" square with epoxy potted electrical bits. You might can look at the parts diagram on the JD site to get an idea where it's located.
