1990/91 yamaha 200 hp alarms.oil injected,

[Chris@ Langley]

when under power I've started experiencing my yamaha lcd controls go into alarm. That is all indicators are highlighted and buzzing.low oil, low oil pressure aswell as good oil level.(Oil levels are ok) From what I've observed my battery indicater also starts flashing just prior to going into alarm.All lcd instruments start flashing and I have to drop below 1300 rpm before I can power up again. Sometimes alarm returns imediatly or several minutes/hour. engine is charging at approx 14.5 volts both battry's are good and have clean terminals have swapped both to try. With ignition on but not running battery indicator starts flashing within a minute. Sometimes there is no response from ignition or power tilt then all of a sudden it's back.ie: go to start and nothing, nothing,nothing,then ok I am going to go connection by connection but do not have a wiring schematic. any suggestions would be greatly appreaciated. thanks in advance

I think you are heading in the right direction . Check the all the plugs for corrosion or bad connection guages,ign.switch oil tank and on the engine. sounds like something loose
