My daughter has a 2010 bronco model 13wx78ks011,,42 inch cut,,kohler engine..... using jumper cables direcktly to the starter it will start with no problem. When trying to start in the normal say, it is dead,,, no nothing,,,, only the head lites working..... tried new selonid (just as a last ditch effort), started once ran good. Then turned off and dead again..... I'm thinking maybe the safety switch for the blade deck may be bad ???? Battery checked and is good,fuses good,,, seat safety switch by-passed but no starting.......... Any suggestions from here????
