Speedo stuck at zero

[GO BIG]

So this weekend i took the trailer out and i got stuck in some stop and go traffic going up a good sized grade. When i got to the top and passed the accident i noticed the speedo stayed at 0. Another half mile the speedo jumped to 50 MPH and was fine. Any reason this would happen on it was just a one time thing and I shouldn't be worried.

, wish I knew what the problem might be, dont have a clue.


Is it just the speedo that is sticking at 0, or are all the gauges dumpin to 0?

does the speedo do any funny dances when it isnt stuck at 0 ?

it sounds to me like there is a loose plug, or crudded connection somewhere. unfortunatly those can be a cramp to find sometimes.

on the bright side....when the officer pulls you over and asks if you knew how fast you were going, you can confidently tell him "i wasn't going at all!"

Speed sensor could be on it's way out.

I had it happen to me once... I was pulling a hay wagon out of a field and some of the tall grass got a hold of something. I had no speedo and it shifted like crap for about a 1/2 mile till I could get to a place and stop. I did when a car went out in front of me and I stopped, when I restarted, the speedo and shifting was fine.

I crawled underneath and there was some grass stuck to some things under there, but nothing major. Didn't see anything, couldn't find anything that seemed loose, so I've been driving it the last year and a half with no problems.

Do the obvious, wiggle all the wires on the sensors on the tranny once, and see if it improves.

Does your odometer still work? If that does and the gauge doesn't, then you might have a dead speedo, with everything else being good.

Well like i said it was a one time occurance and it hasn't happened since. The truck was running real hot moving up the grade in the stop and go so I think is has to do with a heat problem. Once i got moving and onto the other side of the hill kicked right back up.

If it happenes again I will take it to the dealer.

My guy over at Galpin said they have been having a problem with the cluster gagues with the Harley trucks. I will have the cluster switched when I take it in.
