boab3 164 Posted March 14, 2015 Report Share Posted March 14, 2015 Hi all . I've now finished my project long saga vr6 in my mk2 I've fitted the mk3 dashboard I've got the link in for d8-e2 for my cluster but I've no fuel or temperature gauges working . I've had 3 clusters and new sensor fitted but no joy . I removed the yellow 4 wire plug from temp sensor checked for voltage on the blue/white wire I've only got 2.5volts on this . should it not be 10v from voltage regulator?any help appreciated . cheers Link to post Share on other sites
J4Y VR 36 Posted March 14, 2015 Report Share Posted March 14, 2015 I think you got a earth problem check the earth wires by the back of the cylinder head with ring terminals on it. boab3 1 Link to post Share on other sites
boab3 164 Posted March 15, 2015 Author Report Share Posted March 15, 2015 Yes I had a check of things today I have a problem on the earth connection the pin 4 fluctuates with voltage when it should be zero as it's an earth I've had a look on a2resource the brown/white wire from g1/5 has a fluctuating voltage when running . must have a wire connected up wrong at fuse box I did notice it comes from cluster goes thru fuse box and comes out at mfa earth and then cylinder head earth connection..need to get another look tomorrow Link to post Share on other sites
boab3 164 Posted March 16, 2015 Author Report Share Posted March 16, 2015 Anyone know why I have such a low voltage on the blue/white coolant sensor wire?I've got about half a volt I'm sure it's either5v or 10v I've checked at engine harness multiplug and still same voltage Link to post Share on other sites
boab3 164 Posted March 17, 2015 Author Report Share Posted March 17, 2015 Due to me shaving my bay I extended whole harness and one wire wrong mixed the vss wire with coolant gauge sender supply it pulsed the supply to earth which I think stopped voltage regulator supplying gauges with a 10th silly mistake sorted now . Cheers for the help much appreciated<br/> Link to post Share on other sites
