[QUOTE="Tazza, post: 28627, member: 82"] PWM as far as i'm aware of is pulse width modulation. The computer esentially controlls electricial pulses to the coils to alter the strength of the magnetic field to vary the amount the spool moves inside the stem. If you have proportional aux hydraulics (which i'm pretty sure your machine would) they control it via PWM instead of the older ones that were either fully on or off. Being a later model machine it could be the switch which is essentially a vairable resistor instead of an of and off switch. These can and do go bad. Then you have your coils on the control block. If any of these fail, it could give you an error code. Even the wires between. The coils aren't that expensive, around the $40 mark, so throwing one at it isn't too painful. The control switch on the other hand, i'm guessing you have to buy the entire hand grip, or at least a good section of it that is no doubt expensive, there is a limit to how many things you can try throwing at it. Owensge - have you managed to fix it at all? [/QUOTE]
