I'm new to the Valkyrie I bought a 98 Tourer with 45,000. I live in MI and picked it up in Jan.
It finley warmed up and the snow is of the road so I took a little ride, I really am going to love this bike.
I did notice that the tach works only part of the time. All the lindicator lights work and the tail light works all the time so I don't think it's a short.
I guess I'm lookig for a starting point. I did read the posts on this subject and could not match my issues with the likely fixes. Is there a test to see if the tach is bad?
Thanks for all the info I have gotten from this forum so far. It's been helpfull and entertaining.
Can't wait for spring!

I think I would start by searching the wires to and from the tach. A service manual would be a big help in traceing wires and looking for the proper connections. With the tach working on and off I would think bad connection before a bad tach. You can download a service manual from Dag's site in, I think, Norway? Search this site for the link. Takes few minuets to download, but worth the time. Maybe someone has had this problem before, and will give you a little better answer, but, will give you a place to start  |

Thanks I just finished downloading the service manul and I'll have something to start the search. The temp light does not light up when turning the key on before starting so that may be involved in the problem.

Had a similar experience with mine many years ago. It was simply the brake light bulb. In the Standard or Tourer the tach is wired so that if the brake light or fuse for it goes out the tach goes out too. A handy way to tell that your brake light isn't working. Check the brake light bulb and the fuse first. Good luck.

Mr Nuts beat me to it....... Tail/Brake light bulb burned out. One of Honda's safey features. |

Well the tail light and the break light work fine at least when I can see it but then so does the tach.
I think I'll start with the conections in the tail light and work foward from there. It's still to cold to ride here anyway so I'mm just happy to work on it.

Tail/brake light bulb is where I would start too. Be aware that sometimes folks have replaced the tail/brake light with an led or some alternative. I had one for a while that actually had a transmitter in it that sent signals to led brake lights mounted on the back of my helmet. It eventually caused trouble so I ditched it. There is also a connector under the rear fender that is sometimes a source of trouble too.

Thanks for the info. It's to cold to do much today 25 and sunny. The guy i got the bike from painted the fender so it might just be a loose conector. I did play with it last night and the tach worked but was jumping around a bit . After a while it just quit working,. I shut the bike off and restarted and it worked although still jumpie then stoped working again. The tail light and break did not flicker. I need to get it over to my friends shop and start to check everything over. The bike has no records of maintenance so from reading the post i think a top to bottom preventive maintenance is needed. Is there a test to check if the tach is bad?

Well I took apart the rear light and checked all connections. I also pulled apart all the connections in the headlamp and cleaned and lubed all the connections.I checked the bulb and could not find anything wrong.
When I run the bike for 4 or 5 minutes the tach quits. I played with all the connections and can not get it to come back untill I restart the bike. I pulled the rear bulb and the tach still works until 4 or 5 min then it quits again with or with out the bulb in it.
I'm starting it may be time to shop for a tach. Any suggestions?
I used Radio Shack lube and cleaner seemed to work well I even sprayed some into the directional signal switch and it works way better.
The tach really never runs smooth it seems to jump around alot.sorry I'm rambling but I'm trying to get all the info I my post.
My bike is a 98 tourer with 45000. It has been well cared for and everything else works fine.

A failing tach is one of the symtoms of an alternator going bad. Have you checked to see that you have greater than battery voltage when the engine is running?

I did check that the headlight did not dim when hitting the brake but it wouldn't hurt to put it on a meter. Could a bad battery couse the tach to jump like that?

Well the next thing I think you should do is to buy a second Valkyrie. That way you can exchange the tachs and see if that fixes the problem.
If your wife won't go with that...you'll have to keep checking electrical.
Bad battery, or bad connections could cause it.
Alternator going bad can cause.
Fusible link (under black cover in right side wiring) would be the next thing I would check.
Starter relay after that I would look at to make sure it hadn't fried or gotten wet.
A thorough search of the Old Tech Archives might reveal other ideas too. Good luck.

http://www.rattlebars.com/mtz/starter.htmlThis is a good page to bookmark. About halfway down you'll see a drawing with the fusible link and starter relay. It also describes maintenance of the common things that go wrong. Hope it helps.

Tach wire goes thru the headlight bucket, I think it is a yellow wire with a connection in the housing. On my tourer once while wiring some driving lights I knocked the connection loose and the tach didn't work until I redid my handy work.

Yellow/green tracer is tach wire from ICM, - looks like a connection in the bucket. There is a green as well - I believe that to be ground. |
