    1992 CH613 Electronic malfuntion code 4-2

    I just purchased a 1992 CH 613 with a E7 300 .... not running .. I did after a day of checking I found the fuel pickup inside the fuel tank was plugged . blew it clear and primed the pump and she started right up ... but, now after 10-15 seconds I have no throttle response ? and a Electronic malfunction light . after reading other blogs in this sight found out how to get the fault codes ! with two faults ,,, one 3-4 telling me " engine position sensor ... I adjusted the sensor on the Pump and this corrected that fault . the other fault is a 4-2 " fan clutch output " can anyone help me with this ? Jaan
