    Well this doesn't look good...

    Mustang 2054 starter issues...

    Has anyone experienced problems with the yanmar starters in these skid steers? Have replaced 2 so far that have stuck and burned the windings. Maybe an upgrade or different starter recommendation? At $600 a pop, this is getting ridiculous. Any thoughts greatly appreciated.
