OK Aspencade digital display Haywire (sometimes)

So the digital dash started working funny.

The first thing was the trip odo adding mileage, like 50 miles.
Then the next day it decided to remain in 3rd gear regardless of which gear I shifted into. after parking for 5 or 6 hours it worked normally.

A few days later it worked poorly and then worked fine.

After an oil chance (nothing suspected, just time for an oil change), strating the bike dash worked normally.

Today I drove to AGSEM (www.agsem.com it is a great lace check it out), about a 3 mile drive from home. on the way there it decided that I was in 3 rd gear and turning 1480 RPM ad the trip odo said 0. After 5 or 6 hours parked it all worked correctly except for a 'something" momentarily changing the speed, sudden almost here and gone.

The temp and gas gauge are fine and halve been.
So i have begun to think about it. aside from what is doing this as a question I have some questions,...

1) Thinking about the oil pressure light and temp ad gas always work but the digital displays for speed, rpm, gear and trip odo work intermittently I am thinking it could be a bad / high resistance ground ...

2) Could it be the one or both of the two big plugs on the right hand side of the fairing? Bad ground or something ?

Well what do you guys think?

when the digital display starts doing funny things, the common culprit is burnt wiring around the top of the soleniod, and the dogbone fuse

Mine has been upgraded to modern blade type fuse as a part of the solenoid. Former owner did it. i could try replacing the blade fuse though.

yep wouldnt hurt to change the fuse, should be 30amp but usually the bad wiring can be seen around the connectors (I think there are 4) near the solenoid
