So I Downloaded a PDF manual for my new to me 2008 crossfire 1000 because when I bought the machine yesterday the sled threw code 18 on the dash. This code is Power valve motor problem. The Manual described to energise the servo motor with 2 test leads to a separate 12 volt source and reverse polarity to turn motor opposite direction. motor checks out good, next do ohms test to motor itself turn motor and read resistance threw entire cycle and both original motor and a spare that came with the sled check out a ok. checked and adjusted both power valve cables to the 35mm length specified in the book. Next removed power valves checked for damage worn spots on the slide shaft cleaned and made sure were freely moving up and down in the channels. Next book says to remove spark plugs and quickly pull cord with multi meter checking for 12 volts dc at the plug. Now here is where it gets interesting there is no voltage present at the plug when either you pull over the engine by hand or unplug and do the test with the engine running so I figured has to be broken wire. Totally disassembled half the sled to trace the wires because they go under the gas tank trace all 5 wires back the left plug on the ecu do continuity test all wires check out a ok. but NO voltage at any rpm. what else could it be?everything seems to be operating very well on the sled but the power valves are not opening and its evident because of the lack of power on the top end. and the servo motor wont turn.
