1990 Yamaha 70 hp LCD Maritime Meter

I have the above mentioned meter that has ceased to work. I am looking for a wiring diagram to check installation prior to searching for a new meter. If you have access to such a wiring guide, please let me know. The meter displays fuel capacity, MPH, battery and a couple of other idiot lights.

Given that it is a multifunction meter, what is/are the failure modes?

Does nothing work at all or is only some of the information not being displayed?

Normally it is the multifunction tachometer that has the warning lights. You appear to be talking about the multifunction speedometer.

A photo would be worth a hundred words.
