Our t300 Bobcat has a electric over hyd solenoid,problem is the fuse blows sometimes it may take 3 or 4 days for it to go somettimes a month,we are ussing it manually for now but it would be nice to fix.
Had a similar problem with a T190 don't know if yours is the same set up, but there was a common problem with the connectors closest to the solenoids on the T190's. Cut the connectors out and straight wire it or use another type connector. Four wires if I remember correctly.
