I have a 2005 VMAX 150 and recently changed my impeller and thermostats. I have and had flashing bar on my gauge just above the thermometer every time the engine is running (regardless of RPMs). I don’t get an audible, but a flash in the gauge. Yesterday I ran the engine on the hose and disconnected both sensors next to the thermostats and nothing changed. I thought for sure if I disconnected the sensors I’d get an audible but I didn’t. Thoughts? Advice?
