Jerky jerky.....

[telboy]

Hi all,

I've just replace the speedo in my Cat after a disastrous day at worksop on sunday. The speedo I put in has worked fine until now.

I've wired it all up fine, but when I've just tested it on the street its jerky as hell. it doesn't move at all sometimes until I give it a push, then its just not smooth like it should be. I've tried a different sensor wire and it still does the same.

Any ideas?

bonded or sintered core? the tape holding it together can come off and cause something similar to what ur saying. I used to have it happen with my lrp motors of the early days!

Hmm, to be honest I haven't got a clue matey! lol

Its a speed passion 6.5 new style. And a Nosram Matrix.

The thing is, that motor worked fine at the weekend with the different speedo?!

Ive seen this three times recently and every time it's been a dodgy speedo.

Strange. Can a speedo turn faulty just from moving it from car to car?

Hope not, as I've not got any speedo if it is the case.

Well only from getting it too hot from soldering i guess? Probably just a coinsidence. I would change the motor first to eliminate it being the problem.

Unfortunately electrics go funny for no reason.
I restarted my laptop last night and now the screen wont work for the first few tries, but it works yesterday perfectly.
