Hello i was going through different threads trying to find any possible reasoning for my 1995 ls400 speedo needle being out by 80kmh, dosent do anything until 80kmh then starts to move perfectly matching my increase in speed eg 80-100 is 0-20kmh on my dash.

I found something talking about realigning/calibrating the tacho on one of the same model and was wondering if you could do the same thing on the speedo. here is the comment in the thread.

also a side note, if you want to fix your tach being miss aligned you have to put the cluster in with the tinted plastic off start your car and let it warm and idle, pull gently on the tach needle, move it to where you think it needs to be 650ish, and push it gently back in, sadly its a crappy fix and im ashamed of it I wish I could give you better but without tearing into my cluster to figure out more stuff I cant write a good tutorial for it... If someone wants to send me a junk/spare cluster for me to tear down and inspect I would gladly write a tutorial up if I can figure out a way to fix it...

Also, on the needles... they appear to be some sort of fluorescent or similar technology, its actually quite interesting, when I was re aligning my tach I touched the needle of the speedo and it lit all the way up but when i took my finger off it turned back off, there seems to be some broken connection on the outside of the tube, the black tape thats behind the needle carries current because I played with it and it arched and burned me!! I would be very interested to tear one of these down without risking my own cars dash...Last edited by Legionofon; 03-14-10 at 10:23 AM.

thanks

 

For my 1996 I smack the dashboard above the speedo with my hand and needle fixes itself. Not permanent solution but it works for me.

 

Might be a lube issue.
