hi guys , ran through tests etc smoked another transistor pack , replaced driver and transistors again held breath and turned on , now works fine thanks trevorb at solutionmhe dot com
Hi Trevb, post me your email and I'll send the manuals to you on the mircocommand system fitted to your truck
no flashing fault codes showing only 9 on display i presume is battery percent , i presume h bridge is inside the long black case behind the contactor rack , only have little knoledge of this truck , have turned steering to left right that drops out motor which is turning slow could do with manual if any one has one thanks for help
if the steering wheel sensor reads straight ahead, and you only have 1 wheel getting traction power, (with all the other info) you may have a bad motor and/or bad "h-bridge" card.
does the dash give any errors when you try to drive??
Yes does sound like a problem with the driver card. If the transistor has been replaced also advisable to replace driver card.
Any error codes?
