The speedo is intermittent, it will light up initially like the photo and at some point fail. No lights for high beam, neutral, mileage, speed or RPM, but both turn signals lights in the speedo work. Everything else on the bike functions normally.

I installed a new battery ( I had no history with the old one), checked the connections above the transmission cover and checked battery connections. I am looking for ides how to trouble shoot. I test rode it today, it started normally, but as I was riding it would fail momentarily and the come back on.

As I said earlier, the turn signals still light up, that would lead me to believe the speedo is still getting power, any ideas on how to trouble shoot would be appreciated.65404

Mine is doing the same thing. I was told those are signs of the ehc going bad. I’m fixing to take off ehc and send it to Curtis. I’ll let you know what he figures out hopefully it is something simple like a bad connection.

Cruz Dog does all your lights work and everything, on mine the high and low beam work, turn signals and tail lights work, the only issue is the speedo.

Im not sure that is the problem.....

This is the first time I've really looked at an EFI medallion speedo. Didn't realize it didn't use a similar tach ring as the others.

Although I suspect the wiring is the same up the backbone so you could have the dummy lights working and the speedo not working as its on separate lines. @SKOGDOG will know

I have to have power to the speedo I would think, since the turn signals work when nothing else on the speedo does. I'm thinking it's a short, bad ground or the speedo itself is going bad.

When the speedo doesn’t work my tail lights won’t work. Turn signals and break lights will sometimes it works sometimes it doesn’t

I agree, it's a bad wire somewhere or just speedo is going south.

just ehc was mentioned and considering it's just an intermittent isolated issue I would go there last.
