well i never thought about replacing it but hey why not (fuel gauge was never accurate even if i filled it up full it sat on 3/4, always out by 1/4). went into dicksmiths got a 8v regulator and a 5v voltage regulator (both $1.20). slaped on the 5v one first, and my fuel gauge read about 1/3 of a tank (it is a full tank mind you), and the temp gauge nothing, poped the 8v one in, fuel gauge read tiny bit just under full (which is correct just did ~40kms) and temp gauge read just under half (which is correct) - before the temp gauge would sit say 1/4 all the time.

i know it isnt exactly 7v but ive used 8v and its caused no issues. i mean hey beats gettin a new dash? $1.20 :D

screws right in just be sure to use the old heatsink from the old one and ur done.

YAY, finally something i can afford to do right now :D

oh oh guess what im doing on the weekend :)

dammit, where do i find it? :redface:

when u take ur instruement cluster out its on the back roughly in the center. it has a metal silver heat sink and the regulator is green - has 3 legs. its all screwed on, no solderin needed.

unscrew the regulator and heatsink, d/c it from the heatsink, clean the heatsink, slide the new regulator on, add a drop of glue on the heatsink so the volt reg can stick to it (hey it doesnt generate tremendous heat but keep the heatsink). screw it all back - done, all up 15min of work. no point replacin fuel senders etc, i mean if u get some sort of readin then the sender aint at fault (as i found out), its this regulator. $1.20 wont hurt. grab the 8v one.

here are pix for comparison of the new voltage regulator (7808 - 8v) pictured on the left and the original on the right. fits fine.

thanks for the picture, now i wont look like a total fool when i go get one :P

may as well do this when im at dse getting the auto shift kit bits

Hi Subby

Is this for a digital display..I have a TP elite

Cheers

Ah sweet, this could be the same problem I am having.

nope, this is for analouge dashs


if your having problems with your fuel gauge with a digital dash, chances are it's the sensor in the tank... they have a common problem of the resistive wire burning out.

yer...thanks again.....changing the voltage regulator sounded easier.......

I'll see if I can look at the sensor on the weekend and give my trusty multimeter a workout...rain permitting.


cheers

Sorry to drag this one up but I have the same problem with my TP station wagon.

I have had a quick look at the instrument cluster but can not see any screws to get it out.

How do you get the cluster out?

Thanks!

see thos vents on each side of the warning lights?? carefully remove them as i have been through hmmm 6 i think(just put a small flat head in the hole and try and pry the vent out) and there will be 2 black screws behind them un do them and remove the whole surround then you will notice 2 gold screws on both the sides of the cluster take them out and then pull the cluster out and remove the plugs :D

heres a picture of the regulator if anyone needed it, the numbers on the pic are the pins so you can put a multimeter on them and test to see if its working right

Hehe, blue, I have a white one and a green one.

8V regulators aren't just quite right, but they do the trick.

Thanks for the info mate I will pull it out in the morning and have a look. Is it easy to disconnect everything before pulling it out as most cars I have worked on have very limited cable length and things can often break without much effort?

How do you test the volt reg with a multimeter to check if it is actually working or not?

theres a fair amount of cable to work with so i couldnt see that being to much of a problem, just have it on a angle so you can get the multimeter on the pins but not have any issues with the cable
as for the pins:
Pin 1 + 2 = Battery voltage
Pin 3 + 2 = 7v

If not 7v replace

Thanks for the help again.

I checked the volts and it measures seven exactly so I guess thats not my issue.

How hard is it to change the fuel sender in a station wagon?
