Scag Electrical Problems

[willijimon]

Hey guys. Quick electrical question. Running a Scag Tiger with the 29 horse Kaw DFI LC. At idle it is neutral on the ammeter but when you kick on the deck and load the system it is discharging (-5). Before I do lots of looking around on it, has anyone had this problem before on their mower and what was the solution. I'd liked to get this fixed and back in the field quickly. Thanks for your help.

does this machine have a generator, alternator, or a magneto?
