I have an Autohelm
ST7000 withe a type 300 computer and type 2 hydraulic drive pump
. Last night after a particularly boisterous trip down the east coast
of NZ, the system blew the fuse on our main switch panel (not inside the computer). After popping a new fuse on and turning on the system, it starts up without any problem, but as soon as the computer tries to correct course from pressing +10, the motor
runs for half a second then the fuse blows. Iíve tried removing the motor
part from the pump
part and itís still blowing fuses
when the hydraulic system is disconnected. Iíve also tried replacing the wiring
between the computer and the motor, but that hasnít helped either.
Has anyone got any input as to what could cause this problem? Can I overhaul
the motor? Is it likely to be the computer?
Any help would be most appreciated - weíd love to get home for Christmas!
