Yamaha 2016 250 SHO, 132hrs with Command Link 6YC Information Station.
Batteries are charged 24/7 by onboard charger
Maintenance done in March (60hrs ago).
Launched and shut motor down while parking. Fires up and went to get on plane and motor dropped into limp mode. Not the first time this has happened, usually just restart the motor and everything is fine. Restarted just fine but error held, See Dealer.
Error 132
Determined not to let that stop me from fishing, got on trolling motor and fished for a while. Googled code but couldn’t find anything. Talked to a friend who said others have had weird codes because of a weak battery.
Pull the cowling and checked the wire connections, also checked the battery connections. Pulled negative battery which looked a little dirty and wiped anti corrosion on the ring terminal and reinstalled.
Turned key and voltage at 12.0. Fires right up voltage jumps to 13.3. No error codes/alarms.
Did notice Voltage drops to 11.7 when running trim/tilt.
Go for a short run, no limp mode, voltage gets back up to 14.0.
Stop, fish a while more, fire up to run back to the ramp.
Fires up normal, no codes/alarms, no limp mode. Voltage is still low but comes up to 14.0 (14.4 is normal) take my time getting out to the main channel, motors warm and running well, push it up to speed, make it a mile or so at 6000rpm and it drops into limp mode. Alarm goes off, low oil pressure displayed. Drop off plane, idle to the bank and shut off motor.
Spent the next hour or so on the trolling motor getting back to the ramp.
The battery is a few years old and only a group 24, with the temps changing it’s time to replace/its being replaced.
Is it possible the sensors are sending false signals because they are not receiving good clean power?
Can someone decipher what code 132 is?
