If the audio warning system becomesĪctivated by the closing of one of the audio warning system switches, the MBT feature is deactivated. NOTE: The Audio Warning System is also connected into the ignition module circuit. RPM the ignition module can add approximately 10‑15 degrees of spark advance to the base spark timing curve. Conversely, if it senses an RPM drop, it will start to retard some of the spark timing. The module will continue to advance timing until it no longer If RPM increases, it will increase timing more. At a given RPM, the module will add a small amount of advance and wait to see if there Mean-Best-Timing (MBT) Spark Advance During light load cruising, the ignition module maintains optimal ignition timing by (pic #2) Goes to the ignition control module for the overheat sensor. (pic #1) The intake manifold temperature switch allows positive current to flow to the TKS heater module to prevent the additional fuel flow path from opening during hot re-starts. it reads as a coolant temperature sender for (analog) gauge uses, it's actually a sensor used for a digital read for the ICM, ECM, etc. Also your marineengine link is incorrect.

#26 should read temp sensor not oil pressure switch like #15 does. Engine Ser # OW380*** Thanks in advance for feedback.Ĭlick to expand.You found it! The yelow and black wires you're seeing is now the new style overheat sensor and triggers the alarm through the ignition control module. I'm just looking to make sure that all my senders/alarms are working and working properly for peace of mind. I cannot get these wire to trigger the alarm in any way though. My only recollection is this said yellow and black wire that connect to the t-stat housing is it. Such wire for the water temp switch for audio warning does not exist. There are wires to the oil sensor and lube reservoir that are tan and blue that trigger the audio alarm. Should this be the sensor/switch that is supposed to be in place of the one as seen in the pic? This is a link to show that the one I have is listed for a EFI engine.

3) p/n 48952 is a water temp switch for audio warning.which cannot find in any manual for my engine type.

2) p/n 802218t port side of t-stat hous (dual wire.one black/one yel) according to manuals that is ALSO a coolant temp sensor for temp gauge.this is listed for engines that have EFI/MPI's.which I do not. 1) p/n 806490t strb side of t-stat hous (single tan wire) controls temp gauge. I still am trying to locate the water temp sensor/switch that triggers the audio alarm in a overheat cond. I finally figured the TKS temp and oil sensors. They have some color codes that do not match up to what I have. they do not list for a 4.3l carb TKS the wiring for the audio alarm. After reading TKS suppl of wiring diagram and colors of wire and where they go.
