changes RPM. Will not
synchronize properly.
a. A Control Head’s Command Signal is vary-
ing.
a. Scroll to the Diagnostic Menu Function
Code H0. Go to the appropriate Station A/
D Count’s display. The Value should not
change by more than +/- 1 A/D Count. If
so, check the connections and if good,
replace the Control Head.
b. The engine(s) is not running smoothly.
b. Increase the engines’ RPM’s in Warm-up
Mode. Scroll to Function Code H0 and dis-
play the Tach Sender’s input frequency.
If the frequency is varying, check the push-
pull cable for movement.
If the push-pull cable is not moving, swap
the Port and Starboard Tach Senders.
If the frequency still varies on the same
side, the engine needs servicing.
c. Defective Tach Sender
c. Same procedure as b. However, if the fre-
quency variations move to the opposite
side, replace that Tach Sender.
