Speedo and rev meter suddenly stop working.

[Bluser]

A nice warm morning and a trip to Tesco is on the cards. We start off everything is normal and after 500 yds I look down and the rev meter has stopped working, on the way back and the speedo isnt working.

Any ideas ?

The needles have been known to stick on the LS400 - a whack on top of the dash may free them.

a robust " tap " often works for me on my 95 Mk3 over the years ............  my rev counter has always been ok tho'  the speedo tends to stick at zero and quickly jars upwards ....  I think it's outside temperature affects it maybe sticking .......  and often the speedo seems to show 10mph LESS than actual ..............

it's a foible of the Ls400 and AGE related ..........  if that's the only problem on a several decades old car then we have very litle to whinge about eh 😅

Good luck Mr Bluesman .  hope you're all ok ?

Same happens very occasionally in both my 400s. A thump onto the top of the dash fixes it every time. Nothing to worry about.

Well thats that sorted. My garage man took out his highly technical rubber hammer and with one swift blow both dials come back to life.

Another case for the "early lead-free solder" category?
