BE-18 BODY ELECTRICAL SYSTEM — Lighting (b) Check that there is no continuity between terminals with the rheostat turned off. If operation is not as specified, replace the rheostat. [DIAGRAM: Shows OFF position rheostat with multimeter showing "No continuity"] Light Control Rheostat (Digital Type) INSPECTION OF LIGHT CONTROL RHEOSTAT INSPECT RHEOSTAT OPERATION Connect the positive (+) lead from the battery to terminal 1. Connect the negative (—) lead to terminal 4. (a) With the brightness at minimum, check that there is 9V between terminals 1 and 3. (b) Gradually turn the rheostat toward the brighter side and check that the voltage between terminals 1 and 3 decreases from 9V to 0V. (c) With the brightness at minimum, check that there is 0V between terminals 2 and 4 and 12V when brightness is at any other level. If operation is not as specified, replace the rheostat.
