Year 2000 SX/LX150TXRY's
I just installed new Yamaha digital tach's, FMM and Speedo due to sun damage and mottled LCD's.
Just love them being refreshed and new.
I had noticed when I had a previous overheat condition (with the original tach's), that the first few overheat alarms and 2000 RPM protection mode encounters, that the engine tach would indicate the flashing overheat symbol. After a while, even though I would still overheat and go into audible alarm/protection mode, that I lost the visual flashing temp indication.
I cleared the water jacket passages with a comprehensive Rydlyme treatment. That's another story too long to tell now.
So having installed my new tachs, I figured I'd test my overheat alarm by jumpering the pink to black wire at the thermo switch. While I got the audible alarm, I still have no visual flashing thermometer indication.
What would be the usual suspect, how do I trouble shoot this system, I also want to trick the oil supply system to ensure it is working properly.
As I write this, I realize that I only jumpered one of the stbd engine thermo switch's and nothing on the port engine. By "jumpered" I unpluged the thermo switch bullet connectors and plugged the engine side into itself.
