MDofTW Posted November 10, 2015 Share Posted November 10, 2015 Hi all; Mk 2 Vitesse CV; in the last few days I have intermittently lost both fuel guage and temp guage, plus, at separate times, wipers and heater fan. Maybe brake lights too! Overdrive works fine, and (thankfully as I'm enjoying driving to & fro work in this warm weather!), headlights do as well. I reckon someone's going to say I've got dodgy earthing somewhere? Thanks all. Steve. Quote Link to comment Share on other sites More sharing options...
nang Posted November 11, 2015 Share Posted November 11, 2015 I would blame the voltage stabilizer that sits behind the speedo for the gauges mis reading. Earth wire dropped off mine once and did this. The rest probably dodgy earth or loose / dirty connectors or fuses.Tony. Quote Link to comment Share on other sites More sharing options...
herald948 Posted November 11, 2015 Share Posted November 11, 2015 I vote fuses! Quote Link to comment Share on other sites More sharing options...
MDofTW Posted November 11, 2015 Author Share Posted November 11, 2015 Aha - I think Tony has it - the speedo is currently not where it should be ( don't ask!), and all the bits behind are just flapping around in the breeze! Fuses are good. So I think that explains the fuel & temp gauges. Thx both for input.BUT, does this explain no wipers, fan or (now) indicators or brake lights. The only electrics that seem to be working now are lights (all ok), and overdrive! If they are dodgy earth - where? And why suddenly all going wrong? Perhaps first winter damp setting in? Thx.

nang Posted November 12, 2015 Share Posted November 12, 2015 Sorry, but I think you're going to have to systematicaly work your way through the wiring, checking bullet connectors and the security of earths.( Clean and shiny terminations) etc. A voltmeter would help.Tony.

Jonny-Jimbo Posted November 13, 2015 Share Posted November 13, 2015 Particularly a multimeter with a 'buzz' function to check continuity. I bought one when at Uni and it's doing well, only cost £8, but it's got all the functionality you'd want. Got it from this place - http://uk.farnell.com/ Quote Link to comment Share on other sites More sharing options...
ferny Posted November 13, 2015 Share Posted November 13, 2015 Mine was earthed on the bulkhead by the battery. The wiper and heater have their own earth wires so checking continuity there is easy. As it's both I'd almost rule out bad switches straight away. I've earthed almost everything individually on my car now. I'll count how many wires there are one day but I'd say it's well over 20 spread over three earthing points! Quote Link to comment Share on other sites More sharing options...
Paudman Posted November 15, 2015 Share Posted November 15, 2015 Earths are funny things. My GT6 has suddenly lost interior lights and dash / main lights until the ignition is switched on whereupon all works as it should. I'll have to investigate further... but I use the late Spitfire earthing cable that goes to both the bulkhead and the battery, so I'd have thought it would be over-earthed...

MDofTW Posted November 15, 2015 Author Share Posted November 15, 2015 Thank you everyone - I will do a bit of digging about as soon as I have a bit of time, and report back. Quote Link to comment Share on other sites More sharing options...
