I replaced the Kawasaki FH541V-AS24-R 17hp on my 2004 turf tracer hp with a Kawasaki FH580V-DS21S 19hp. The new engine runs fine but when I try to engage the speed control lever, or PTO lever the engine dies. The only difference in the wiring is the new engine has a red wire for an electric clutch that the old engine did not have. I don't know if this would cause the problem or not. Any help would be appreciated. Thanks.
