Speedo goes dark and Turn Signals are Flashing

[Chuck3d]

So like in my into, I have questions and you guys have seen it already... So I got the bike running and the only issue I was having was the horn didn't work and the turn signals didn't operate, Although I did have all the marker lights on. I wasn't really concerned about either of those not working. I was taking it out for a slow warm up because it hadn't been driven in quite some time. All was well until I noticed that the turn signals were flashing and I had lost all the speedo information. Then the speedo information came back but I ended up with the right signal on and couldn't turn it off. After parking it I can start it back up and I'm back to everything working as before without the horn or turn signals. The battery power is 12.90 and I have just the normal LEDs on, on the EHC. Any thoughts??

Pull the connectors and clean them and apply some dielectric grease to keep them sealed watertight.

Awesome. Thanks for the help. I'll give that a go. I appreciate the quick reply's.

And while you're at it, clean and tighten the battery cables.

Make sure it is charging. Low voltage will do that too.

Yeah, looking again, start the bike and rev it up to about 2000-2500rpm and see what voltage you get -- should be 13.8-14.4v if not investigate your charging system.

So I've pulled the connectors and found that one of them (connector A) has been opened. So I guess I'll spend a few hours doing a continuity check from the main connector to all the individual connectors. And see if there is a wire inside that's either lose, broken or the pin has been pushed out.

Are/were the flashing turn signals used as a diagnostic tool during the original production run? And is there a software peek/poke program used for that USB connection to help troubleshoot issues?

Before you go crazy do what JBM and Mr. Wright suggested first. Check the connectors for damage and if they look good replace the dielectric grease and re-install them. Your battery seems good but have it load tested anyway and reinstall it making sure the connectors are clean and tight. It can not be stated too emphatically but these bikes need a solid power source or all bets are off and anything can go wacky. Grounds are just as important as the power supplied as well.

LOL. Ok, I'll try the cleaning and dielectric grease. In full disclosure, I have an OCD thing for wiring. Some of the products I work on and troubleshoot have thousands of wires and hundreds of connectors.

Good !! Your electrical skills will come in very handy with these bikes.
