Trying to help a friend with his Mustang 2070. He was using it and it died. It will start and run a few seconds and then die. They bypassed a pressure switch and it will start and run but still no movement.
You have no charge oil pressure. Keep starting it and you'll ruin $10,000 in pumps and motors. Probably stripped splines on flywheel pump coupler and / or pump shaft. That switch is there to keep you from burning up your hydrostatic system.
Thanks. They finally brought it to my shop and i tore the charge pump off and the shaft was broke. Thanks for the help.
