Half the people on this thread are not reading the thread and adding to the confusion. Some are trying to solve Richard's problem wilth his 85 190E. Richard doesn't have a 190E. In fact he never said what he had until I posed the question. About 9 posts up from this one he states that he has a 49 state 87 300E. Also I believe the thread has switched from the original question posed by 69 and shifted to Richard's question about only getting a constant 90% reading istead of a 50% duty cycle reading. End of Cliff notes.
