Service Magazine SEPD0636, 01 July 2002, "New Rotary Position Sensors Are Used". Disregard this article. There is a correction to the list of models at the beginning of the following article. See the article that follows.

Description of Change: New rotary position sensors (9-32 DCV) are now used. The new design of these sensors will eliminate failures of the internal circuit board that are caused by high vibration and overstressing of the part.

Adaptable To: The new rotary position sensors (9-32 DCV) and the former rotary position sensors (9-32 DCV) are shown in Table 1. The new part numbers are direct replacements for the former part numbers.
