Suzuki DF225 RPM and Fuel gauge no working

[linesider04]

I was out today and suddenly my Tach and fuel gauge top registering. I just installed and EP20 into a Lowrance HDS-8 unit. I was able to see the RPMs through the head unit though. All was working fine when I started out and ran fine for a while. Any thoughts on this? Thanks

Fuses?

Check grounds?

The last thing you touched is usually the first problem. Check every connection you touched.
