Electric

[helderteixeira]

Hi, my experience after 3 months owning a Tuscan!!

I'm starting fixing some electric faults in my Tuscan.

1 - switch indicators would not stay when turning right, after forcing to the right the high beams were turning on. Not resetting (cancel) when turning the steering wheel.

Fix: toke the switch out and there was some parts not in place inside of the switch indicator box. Got everything in place and the indicators and the high beams are now fully working. Even the cancel function is working.

2 - replacing the speedo plate from mph to kph.

Fix: taking the dashboard out, simple to change the speedo plate.

3 - needle not on the zero position.

Fix: I was not able to fix yet, but i think if I replace for a smaller pivot pin that attach the needle to the gear pin it will get the switch turn on in a lower position, make it to the zero.

4 - Lcd missing lines

Fix: since I had the dashboard out, I toke my chance and remove the lcd and cleaned everything, it's now working perfectly.

5 - intermittent wipers not working

Fix: the switch that adjusts the speed for the wipers on the steering wheel had a broken wire. Got that in place with my solder iron. The wipers now fully working.

Issue today: I have left the car parked outside (heavy rain, today) when I got home from work, I have check the car and everything looked OK. 10 minutes later, I was going out and I saw the lights on (main beams) obviously they were off since yesterday, but just to double check I have checked and the switch was on the off position. So my only option was to go straight to the fuse box and remove the fuse for the main beams. After removing the fuse the lights still on?? So removed the one the says deep beams and I was able to turn them off!!!

-Any advise for what can be the issue??

The only thing was the heavy rain and strangely they just turn on after 24 hours after I did all the repairs ???

Seems that my electric problems are really a pain to get them away...

To fix the speedo needle not being on zero you can locate the speedo micro switch which from memory is behind the face plate and gently bend its operating lever which is triggered by the speedo grub screw so that it triggers it at a different place.
It is a bit of a pain as it is trial and error to get it right.

Hi,

I was thinking replacing the pin for a smaller one the opposite thing for bending the plate on the switch.
I’m worried now why the lights were on? Any suggestion?

It could be that the heavy rain has found a way in to your car, possibly around the windscreen and has got your fuse box wet which has caused a short circuit. It wouldn't be the first time I've heard of this.

as above sometimes water gets into fusebox have a good hunt round drivers foot well for any leaks

[helderteixeira]

Thank you, for the help. Should I do anything or just wait to dry ? Should it be better to unplug the battery?

[helderteixeira]

Can someone please, let me know if this is the normal behaviour:
I turn on the ignition key and the lights inside the speedometer they turn on as well. Should they turn on only when you turn on the switch lights?

The binnacle/speedo lights do come on with the ignition 'ON'.

I'd agree with comments above regarding moisture/dampness on fuse-board. May be sensible to lower the fuse-board and check for signs of tracking/blackness on the unseen side. Might pay you to get a standard relay and methodically substitute the relays in your car for the new one?

Consider using a fan heater to improve any moisture removal.

Maybe a relay in a wrong socket, due to this fault there can be a a back current
to the ignition current circut.

Hi,
Thank you for the help again. i was able to resolve most part of the issues. I can see that the water is getting in the car i think from the windscreen since i was looking for the fuse box a drop of water fell out on my face from the fiberglass around the windscreen, now I'll try to take the dashboard top off to seal everything with silicone (from the inside) had water too on the pilar A from the passenger seat. I'm still struggling to find the Alarm unit and the immobiliser, i know that the immobiliser was changed for sure because the old one on the boot. I have made a new "remote fob, the one with 2 buttons open/close" base on the number from Car owner manual, but the new remote does not work even with the alarm in programing mode. I'm trying to locate the alarm because the light on the socket for the fob is not on and the button to close the doors from the inside is not working. i think that connects directly to the alarm. Since I'm taking the dashboard top out gonna check if it's there, remember that the old owner said that he had to replace the immobiliser, because of the water damaged the old one. If someone knows the alarm location, can you email me please: [e-mail].
Regarding the zero position for the needle,, when i turn on the ignition it stays in zero, when i start driving it's not going to zero it stays one click above zero. if i turn off the car it resets the needle again to zero, zero position. is it like this ??? or something related to electric speed sensor??
I am close to get all the electrics back working again, I JUST LOVE MY TUSCAN...

Can anyone tell what's this box for ?found it completely loose inside of the compartment for the head lights, from the driver side. Is this the right place for this part? How is attached in place?

[nawarne]

^^^The picture is of the carbon canister.

Vapours from petrol tank are passed through carbon to neutralise. Any collected/condensed liquid is purged to inlet/throttles to be burnt in engine.

Gross liquid, if found in canister, can affect engine running.

Thank you, Nick.
Is there a place for this or it simply goes inside of the compartment freely?

I "think" the triangular shaped moulding shown on your photo, allows the unit to be clipped onto a metal bracket fixed to the inner 'wing' in the headlight compartment...It's fixed on my Mk.1 Tuscan,,,I can't move it out of the car at all - by just pulling it.

There should be a drain hose from the canister, exiting the car just in front of the front driver's side wheel. If you don't have this then liquid cannot drain from 'can'.

Thank you, Nick.
I'll have a look

Still fighting with my electrics:

I'm trying to get the center locking button to work. Was never working from when I bought the car. I was tracing the wires and I know that button uses the orange and black and black/grey wires. There's a plug underneath the Center console that is not connected anywhere. Does anyone know if this plug should be connected??

[helderteixeira]

Any Help Please?

Hi,

That is the Driver Seat Belt plug. 2 Pin connector; 1 - Slate/Black 2 - Black

[helderteixeira]

Hi Pack1uk,

Thank you, for your reply. I'm not aware that the Tuscan was equipped with belt sensor. i toke the seat's out last weekend and did not see any plug from the seats/belt. Any advice how to troubleshoot the central locking button?
