Hi Folks,
I have just changed the impeller and both thermostats on this engine.
The over heat alarm sounds constantly even before I put the boat in the water.
I disconnected the thermo switch port side and the alarm stays on, disconnected the thermo switch starboard side and the alarm remains on.
I traced the cables back from the thermo switches and there are no breaks or burns and look ok however both wires for both thermo switch wires join together and then go into one connector. This connector has some sort of diode or resistor that was broken. (see pics)
Just got back from the Yamaha dealer and they had no idea what it is and it does not appear on their workshop spare part diagram so could give me any info or order replacements
I have attached two pics.
Any ideas what this is part is and if it can be removed and the wires connected directly?
Is this an after market modification and why?
Would this broken piece cause the overheat alarm to stay on constantly.
Any help much appreciated.
Thanks
Andy
