erratic fuel gauge

[edoh]

sometimes flickers into life and the dial moves up the gauge to where the petrol roughly is. But most of the time nothing. A full tank has always only read three quarters on the gauge - when its decided to move up the gauge.

Where would it be best to start methodicallhy looking at the gauge - with what checks?

Mine has exactly the same problem ,other than my full tank is at half... so I've got about £30 of emergency fuel... I've not tackled it yet, so afraid I can't help!

there is a gauge check..
if that pans out ok then it's (usually) the sender, either a broken wire or (usually ) an earth fault.

tank off for that one

don't they're all crap...
20 odd vans n not one that works perfectly yet, soon as they hit the red they go up n down like mad!

Mines even worse - soon as it gets anywhere near the red, you've got 500 yards of fuel left.

i'm going in!
(to the multi plug connector that is)
the fuel gauge has been identified as the lilac/black wire - in the number 7 slot -

as my clock has also stopped working - 5 slot - red wire -##i thought i'd check both -
what should i be looking for - and whats the best way of cleaning these little fragile connectors?

As it does work some of the time it must just be a loose/dodgey connnection somewhere. Check the little nuts on the back of the fuel gauge are tight. Same on the clock make sure the nut and sleeved bit are snuggly fitted. Check red wire should be constant live, check you have 12v to one side of fuel gauge- follow track from LH prong (iirc) of voltage regulator to fuel gauge with ignition on, voltage regulator itself should be fine as temp gauge works from it as well.

If the tracks on the PCB is knackered i'll bring the kit and show you how to do a hard wired setup for fuel gauge, temp gauge and clock on friday. Its the same as is on mine with the extra bit for temp gauge, mine took about 10 mins to do

wowee!

thanks so much!
