I'll try and do that later today.

I've had a closer look at the pcb and the back of the temp gauge and can now see that two wires attached the the gauge disappear down into the guts of the dash and where the pcb plugs into the wiring loom some of the circuits are broken or damaged. It looks like, as you suggested, the gauge has been...

I did wonder that myself because there are a couple stray wires that have obviously been added at some point. I'll try what you suggest re testing the chip and get back to you. Won't be till next week now though because I'm taking the bus on a trip to Anglesey tomorrow for a weeks camping. Just have...

Maybe this is where I'm going wrong. I have simply pushed it into the little receptor that's attached to the pcb. Should I be soldering it into that. The old one just pulled out once the tab was unscrewed and I assumed it was a push fit. Didn't ever test the old one just assumed it was faulty as eve...

definitely an L7810. Should I be going for the L7810C. I have to say I've not been following the wiki article but it looks like mine has gone in the same way.

Its an L7810 1.5 amp. its screwed onto the back of the temp gauge through a small rectangular metal plate approx 3cm by 2. I haven't removed or lost anything so whether that's the heat sink or not I don't know.

The voltage regulator was fitted the way suggested, tab facing out writing to pcb, i tested the voltage come off the voltage regulator and its reading 11.7 volts. I tried putting the voltage reg in the the other way round and still no change. I also took it out completely to see what happened and bo...

I'm going to have to check this again tomorrow, I've been taking a reading off the back of the temp gauge and I need to double check which way round the voltage regulator's facing. Thanks for the help so far, I'll be back on tomorrow pm.
Cheers,
Will.

Well I think so but as there was no info on the new regulator regarding which of the pins were pos or neg I just put it in as suggested on the other thread which is back to front. Do you think I should try it the other way round or will it be damaged now?

So 2 weeks later and I've tried replacing the transistor on the pcb on the dash with no effect, the temp gauge is still going way up into the red and the fuel gauge is a bit erratic. I tried testing the voltage on the back of the temp gauge and it seems to be reading about 11.5 volts (should be 10 a...

Thanks for that I'll check out those treads. Since I was last on I tried making a new earth for the temp sender because I'd read somewhere that if a sealant has been used around the pipe joint, the earth could be lost. This had the effect of making the gauge work but it now goes way up into the red ...

Hi, I wonder if anyone could offer any clues as to why my temp gauge is playing up. Sometimes it doesn't move at all, sometimes its moves halfway across the dial then drops back to zero and remains there but usually it doesn't move at all. I tried fitting a new temp sender which briefly seemed to im...

Thanks for that, I'll have a look.

Hi T25 camper, just wondering if you managed to sought out your aaz turbo return pipe. I'm doing almost exactly the same job and have the issue and if you sorted it maybe you could pass on your knowledge to me.

Cheers,

JX 1.6 to AAZ 1.9 turbo conversion. Good evening all. I've just fitted an aaz turbo to a jx manifold and after rotating the turbo to realign the oil inlet/outlet and managing to persuade oil inlet pipe to bend back into place, the outlet pipe is now way out of line and looks as if it could with an e...
