MidnightRacer Posted July 25, 2011 Share Posted July 25, 2011 Been searching for a little while now with this strange little problem on my recently acquired 350z but turned up nothing so I thought I'd document any progress incase it happens to anyone else.. Basically. on a particularly HOT day the speedo started to play up. while sat with the engine running the speedo climbs to maximum and the digital speedo display shows 280, obviously then I'm putting in some serious mileage while stood still!. This then randomly varies anywhere between that and zero. Oddly enough when you get above about 25mph it returns to normal only to jump up again when you stop. If I open the windows and let the interior cool down it works perfectly normal. As its a JAP import I thought the first thing to look at should be the speedo converter which I located behind the dash. Imagine my surprise when I found this abortion behind the clocks! I've now removed all the mess and soldered the connections up properly so I'm hoping this is going to have some positive results. I'll report back on my findings!

MidnightRacer Posted August 1, 2011 Author Share Posted August 1, 2011 Well just a little update on this. Unfortunately my wiring fix didnt work 100% and the fault was still there if not a little better. It was always going to be one of those guessing games between the clocks and the speedo converter and I knew I'd probably get it wrong so I managed to get myself some UK clocks cheap and took out both the original speedo and converter. I'll post back in a week or so when I have fully tested it! Quote Link to comment Share on other sites More sharing options...
MidnightRacer Posted August 29, 2011 Author Share Posted August 29, 2011 Having removed the speedo converter and clocks the problem has gone away completely so I can at least put it down to one of those. I'd be tempted to say its the speedo converter but I guess I'll never truly know! Still worth a thread for other people who come across this fault I guess!
