Does anybody have a wiring diagram for a Wheel Horse518-H, this is the Onan engine. Think I have found starter but not sure, looks like to get to it would need to pull engine. I think battery but before I buy a new one I would like to check all connections. Started good 2 weeks ago, today when I turn the key nothing at starter but gas guage drops back to bottom. I put a load tester on and it reads 12 volt but when I put on load it drops to 10.5. Am posting on tractor talk as well. I can see 2 fuses at bottom right corner of battery but cannot get my hand in there, can they be connected to start system? Have found nothing on Red Square to help with anything on this unit, most is older tractors.

Thanks, just what I needed. I have had this tractor for just a year and evidently all safty switches have been removed or disabled. Sure help to know what goes where. Anybody know where the alternator is on this thing? Supposed to have an oil filter that I paid to have replaced but I cannot find a filter.

Your welcome Leroy.
As for the oil filter. Not 100% positive. But Look on the side of the engine behind the flywheel down next to the frame. Most are covered by the cooling shroud/tin. You should be able to see bottom of the filter.
Or between the "dash" and engine down next to the frame.
