Brad,
Starting issues yes about every few times that I use the machine, I have to put an external battery charger on and charge the battery before I can start it.....Not the starter it is new couple of months ago.
I though that I would run is question by the form. before I go back to the shed.
I may have to let the batter go down a little. I put the external charger on yesterday when I finished cutting grass.
I don't see a regulator in the engine circuit, just stator and Diode, without checking I did not think the diode would be bad,because there is some movement in the Amp meter.
When I put the external charger on it will charge at 10 amp till it backs down to auto charge, which is just flicker on the charge meter.
Thanks for the suggestion and when I do get it checked I will post.
Oh one more thing New battery last fall.
