WD starter/wiring

Finally got back to the WD. Was going to rehook up the starter and I thought I'd check the wiring on the old girl.Looking at the ammeter I see I have three wires hooked to the discharge side, Ignition, lite switch, and one, I believe going to the generator. The other side of the ammeter, the plus side, has the wire to the starter. Is this correct, or are the wires reversed? The starter has never worked right since I got the tractor. First I thought the generator wasn't keeping up the battery, and then I thought the starter was bad. Could it be the wiring all this time? I've had to recharge the batt damn near every time I've used the tractor.
 
Theres only ONE wire on the SUPPLY side of the ammeter, and it gets to the hot ungrounded battery post, often via wiring it to the big post on a starter switch/solenoid where the big battery cable attaches. The other LOAD terminal feeds hot battery voltage to Lights,,,,,Ignition,,,,,PLUS wires to the BAT terminal on a Cutout Relay or Voltage Regulator......i.e. the genny is on same side as loads like lights and/or ignition.

If an ammeter is wired at the correct polarity if you turn on lights or ignition just sitting not running, it should swing over towards - discharge.......if it does the opposite, swap leads side to side as its backwards.

My Troubleshooting Procedure will help diagnose the cause of non charging... Did you polarize the genny and try it??????????

John, when you say the supply side, I take that to mean the side with the plus sign. Is that correct? Thanks, Jim
 
For a Neg ground tractor the + side would be the SUPPLY but for Pos ground that would be the - on typical ammeters. If its wired right if you turn on lights or ignition not running it should swing to - discharge, but if it swings to + charge the leads need swapped side to side
