yamha 703 remote control alarm system test

[pimpelon]

i have a 1992 yamaha 70hp with a 703 remotecontrol box.

I want to test the alarm system for oil and temp.

I have tested with grounding the temp sensor (pink cable) and also oil level (green and green/red). But i only get alarm in tach display, no sounding buzzer.

I have taken the con***** box apart and tested the buzzer (working fine), and at the same time checked all cabels in remote for oxide.

The problem is that i cant get the buzzer to sound.

Anyone have an idea of why i dont get the sound alarm, but ge the visual alarm?

I have had the same situation with a 2000 115txry. Engine peeing heartily, engine oil tank full, engine override stalling engine and the dash idiot light flashing but no alarm. Any ideas?

Must have a broken wire between engine and control box, check continuity of pink wire in 10 pin main harness between control box and engine.
