there is no audible alarm on the engine when the switch is turned on, the temp and oil lights work but no audible. any ideas?<br />also, the low oil light came on, i added additional oil to the oil tank. the light went out, but when i throttle up the light comes back on. there is plenty oil in tank. that scenario repeats itself. i can run the engine at 2500 rpm or so with no light, but throttling beyong that, again the light comes on???? thanks for your help....
