I have a Yamaha VMAX 150 with Digital Tach and Speedometer. I had some problems last summer. Buzzer going off and kicking into safety mode with the low rpm and such. I did not get a temp indicator or oil indicator. Originally I suspected and oil problem but could not find anything wrong. Today I installed a water pump kit and housing. The housing was melted. I also found one of the Thermostats was not opening. I now believe the problems I had last summer were cooling related which leads to my question. How do I troubleshoot the Temperature Indicator on the Tach and where can I find the wiring diagram to figure out if all is connected. Have never seen the Temp Indicator on the Tach since bought new in 2003.
Thanks in advance.
