Clarification on YM 1700 warning lights

[Martin Fox]

On my Yanmar YM1700 I have the three red light warning system. Could someone tell me what these indicate from left to right? Unfortunately, my manual shows a slightly different dash panel configuration. After warming up, my middle warning light has started flashing irregularly. This flashing stops (or at least appears to) when I rev to higher rpms, and stops all together when the headlights are on. I plan on running through the electrical connections rule out any bad sensors, wires etc. Thanks to those who have answered my earlier questions!

Here ya go.

Chg and Oil should go out as the engine starts, and stay out.

Temp won't light until the radiator is about to boil over. The manual says remove and test the bulb monthly.
An easier way to test it: Slide the sensor connector up slightly (near the the upper radiator hose) and slip in a grounding wire to touch the sensor. This will light the lamp, and will also verify that the socket has a good ground.
