Slimg60 0 Posted July 18, 2011 is your fuel and temp gauge working? Quote Share this post Link to post Share on other sites
owen g60 10 Posted July 18, 2011 Temp and fuel gauge are fine. Have disconnected and re connected the loom to the dials... Now have no odometer. Disconnected and re connected battery clock etc now shows random digits ---------- Post added at 01:59 PM ---------- Previous post was at 01:56 PM ---------- Have also checked earth point on drivers a pillar to no avail Quote Share this post Link to post Share on other sites
owen g60 10 Posted July 18, 2011 speedo goes up to 20 mph now.... although some times i have been going a lot faster.... have oil warning and temp warning lights on now.... Quote Share this post Link to post Share on other sites
dannyboy 0 Posted July 18, 2011 one of the components is failing on the back of your instrustment display,MFA unit probably Quote Share this post Link to post Share on other sites
owen g60 10 Posted July 18, 2011 hmmmm..... what would you recommend... new clocks or pull these ones apart and replace whatever is broken?? Quote Share this post Link to post Share on other sites
dannyboy 0 Posted July 18, 2011 i was looking at the wiring diagram and the MFA display/processer is the common to all the problems your having or attached wiring.Not sure if you can remove it,think its part of the printed circuit. at first i thought it could be a diode but you said fuel guage is working Quote Share this post Link to post Share on other sites
owen g60 10 Posted July 18, 2011 im hopefully going to dive deeper into the problem tomorrow........... if i cannot solve it which clocks will fit the car.... does it have to be ones from a G60?? Quote Share this post Link to post Share on other sites
dannyboy 0 Posted July 18, 2011 think so,the vacuum sensor on the back works different to the other displays im led to believe.Theres a few small differences between displays but not 100% sure you can use others. Ask some of the other guys,they might be able answer that. Quote Share this post Link to post Share on other sites
owen g60 10 Posted July 18, 2011 well i have found a set on ebay for £40... could always switch the dials so i still have the DDI facia on them i suppose... hopefully my brain will cooperate and find the issue. Just seems odd that it all fell over together within the blink of an eye Quote Share this post Link to post Share on other sites
owen g60 10 Posted July 19, 2011 I have had near enough the whole driver side of the dash apart.... on looking at the earth point on the a pillar there is a red and a black cable both going to one earth point. The red wire is broken and i cannot see the bit that has broken off..... can anybody remember if the common earth for the speedo and rev counter was red??? and if the fuel/temp gauge was black. would explain why i get random infor on the odo with temp and fuel working and no speedo/rev counter as the speedo and rev counter have a common earth and are linked to the MFA. Thoughts/corrections to my theory please Quote Share this post Link to post Share on other sites
owen g60 10 Posted July 21, 2011 New clocks on route.... should know tomorrow if the problem is solved :) Quote Share this post Link to post Share on other sites
dannyboy 0 Posted July 21, 2011 That red wire is the perment live for the mfa display! might be your prob!!! Quote Share this post Link to post Share on other sites
owen g60 10 Posted July 21, 2011 which pin does that run from on the back of the clocks??? and where would be the easiest place to connect it to, so it has a constant live??? Quote Share this post Link to post Share on other sites
dannyboy 0 Posted July 21, 2011 pin 11 on back of the display should be thin red wire goes to U2 on the back of the fuse/relay box ---------- Post added at 09:10 PM ---------- Previous post was at 09:08 PM ---------- pin 11 display goes to pin 11 on U2 connetion on the fusebox Quote Share this post Link to post Share on other sites
owen g60 10 Posted July 22, 2011 (edited) New clocks now fitted with old dials... All now in working order thanks to Mk3-Damo for the new set at a reasonable price Edited July 22, 2011 by owen g60 Quote Share this post Link to post Share on other sites
