Several Functions On My Gauges Don't Work

[TopsulTime]

2005 Yamaha F250 with round gauges. No speed or trip, no oil or temp data, no ttl or econ

RPMs and fuel level graph work.


Where to start???

Did the gauges ever work or are they new to you?

If new to you I know that the speedo is getting its reading from the speedo hose off the lower unit or (preferred) your GPS. So without a functioning input there you won't get speed or trip.

The oil and temp I would verify wires are hooked up to the respective sensors and verify output.
