Dash doing weird Sh!t

10 posts in this topic

Bought a car knowing it had this issue... now not sure how to fix

 

Short version - the dash gauges play silly buggers. The fuel gauge will periodically give up, and drop from wherever it is to 0 over about 45 sec, then perk back up. Temp does the same, and the rev counter has just once decided to just read 0 while the motor was running. 

 

Where should I start - is this likely to be a dash cluster issue or earth related? Alternator looks to have been already replaced, and it has one of those stupid Japanese earthing kits from battery neg to anything unboltsble

Bad ground - check your battery voltage - alternator output voltage - had similar fault with dieing alternator - seemed fine but lights would come on dash and gauges going on/off

I'd check the dash itself, or test the earths to the dash plugs. Could be dry/cracked solder too.

I have a similar issue. My dash goes black then starts flashing..as well as petrol gauge but never temp gauge. The two lights on the aftermarket gauges also go on and off. Most of this happened after a motor transplant..however i could bang the top of dash and it would go back to normal.

Tonight driving home changed it from tiptronic over to second gear to go up my driveway and it started acting a bit peppy. I notice the dash lights were on but the speedo/rev counter red stick lights were out and the indicator lights were both hard on.when i stopped it started revving high so i turned it off....Help what is wrong!!!

      Hi all. So I've just seen on Facebook about a thing called The Gumboot rally it's on the weekend of the 7th of April. Goes from Hamilton somewhere down to New Plymouth then across to Taupo and also includes The Forgotten Highway which is an awesome road to drive, as I have done it a few times now. If you are interested go have a look on Facebook should be a fun weekend I reckon.
       
      Stay safe on the roads over this time there are some CRAZY people out there who only think about themselves!!

      Help me please Hi iv fitted a dump valve to my vectra c 19 cdti 150 bhp. The 1 I bought was a twinport or receculation valve I don't no just bought and had a go of fitting it my self.  On looking at the car I thought I needed to block the 2nd port so have done bought a t and fitted it on the main intake Of The top Of The intercooler to the inlet on to Of The head.  Ran the bleed pipe and td it in to the on top Of The intake now it's just realeasing through the revs rather than when I lift of it's not because I blocked the other port is it thanks
