Technical More help please "lights"

[seicentoowner]

I have more issues with my lovely seicento. Now what is happening is,
- When the brake pedal is pressed all the passenger indicators are coming on as
well as the brake lights. And
- if I press the brake pedal while indicating it clicks twice as fast as if the bulb has gone (it hasn't).
What am I to do?

I would like to try fixing it myself but could do with some help and advice. It seems- I solve one problem (tracking destroying front tyres) and a week later something else goes wrong (interior light bulb replaced) I fixed that, and now this with the bloody break lights.
I love my little car and want to keep her going as long as possible. but worry i'm going to fail it next MOT or get pulled by the police and get a producer and then have limited time to repair,
Any information as to what is causing the issue would be awesome. And if you could supply me with a step by step guide of how to solve I would love you forever.

By the sound of it you have a bad earth on the n/s/r lamp and when you press the brake it trys to earth through the indicators thus putting them on. Remove the lamp & have a look at the connector block, try & crimp the contacts a bit. It's hard to explain, really.

You might also look at the wiring to the brake light switch (down by the pedals) as it's a little bit vulnerable.

I have a Cinq in at the moment which does all kinds of weird stuff when you depress the brake pedal. (But that'll wait till I've sorted out the head gasket!)

Wiring diagrams in the Seicento Technical Manual (in the Downloads section).

But you really, really ought to post in the Cinq/Sei section, y'know!

Thankyou for your advice, I decided to check the connector block, it was fine. it got me thinking tho that it could be the earth cable further into the bodywork. So i threaded a new cable from the earth on the faulty light cluster across to the earth on the otherside light cluster. Hay presto, working well!! so it is a fault with the earth on the n/s/r lamp. so even tho it wasn't a step by step guide to how to fix so i'm afraid i will not love you for ever. but your advice did lead me to the cause of the fault so I think YOU ROCK!!! :slayer:

When will my Luck improve?
As I said "I fix one thing and another thing goes wrong". It's happened again, I was driving a few days ago and the car started screaming (very unpleasant). I managed to get home. After inspection found the gearbox has no oil, and a massive oil leak from the rocker cover gasket. There is so much oil leaking from the rocker cover that it's run down and covered everything in smelly black ooze. So I can't tell where it's escaping from the gear box. So is it worth me spending two days changing the rocker cover gasket, cleaning the oil so I can see where the gearbox leak is, then changing the rubber seals on the gearbox (having to dismantle most of the front passenger side to replace parts), then re-filling it with oil just to see if the box is ok having driven with no oil? Or would I be better cutting my losses and breaking for parts? If so does anyone know anyone who’d be interested in buying it, it’s a 1999(X) SX. Mot’d till March

what's that got to do with lights..?

rocker cover is a 20 minute job..here's a guidehttps://www.fiatforum.com/punto-mk1...ket-without-having-leak-again-week-later.html

refilling g-box is awkward -but the simplest thing..!!

IF the leak is significant - you'll see it pour out..,

bset to refill g-box 1st, go for a "round the block" drive,
then if all appears good do a clean-up,

preventative maint. is a GOOD IDEA

re: More help please "lights"

Thank you Charlie for the link to the tutorial guide, I'm pretty sure the gearbox is leaking from the rubber seal so filling it up seemed to be a waste of oil but I'll clean some of the leaked oil, and top up the gearbox to check it. You said "if the leak is significant i'll see it poor out" but even a slow leak is significant isn't it?
there isn't an oil level dipstic for the gearbox so it's hard to check the level could it have made so much noise and not damaged the box it's self?
I'm aware that it has nothing to do with the lights. but I just continued the thread i'd created should i have created a new thread?. what preventative maint could i have done to prevent this happening?

hi,
the plug on the front of the gearbox is the filler, AND level hole.

I generally use an allen key - angled down- as a dipstick,
once you see the oil level on the key you can carefully add a little more oil without it running out all over the place,

for the sake of some oil , it could save the hassle + inconvenience of an unnecessary g-box swap,


keeping an eye on the levels, and dealing with any more major leaks is always worthwhile..,

re: More help please "lights"

Hello and Happy New Year. I'm still having problems with the car. I've filled the gearbox with oil, and repaired the leek; it was a loose jubilee clip on the rubber part. So I fixed that. Without the need for a gear box change but it's still squealing when I press the gas pedal. It sounds to be coming from the engine block it's self. It is fine when just ticking over, but even a few revs and it squeals. I have an oil leak from the tappet cover gasket, but there is plenty of oil in the system as I keep topping it up. I've ordered a new gasket from EBay but will replacing a rubber seal/gasket solve the squealing? Or is it the end for this engine?
p.s. I know this post isn't about the light.

Squeal could be nothing more than the alternator/water pump belt being too slack. Worth checking. Can't see it being anything to do with the oil leak (unless the oil has got onto the belt).

 

[seicentoowner]

That's what i thought so i ran it a few mins without the alternator belt, and it still did it- ruling out alt-belt, alt-bearings and water pump.
I tried to change the rocker cover gasket yesterday. but the wind lifted the bonnet off it's stand and slammed it on my head, TWICE! got a bump on the bck of my head LoL. bloody british weather. will continue when the wind has died down.

Try pushing the clutch pedal down and selecting a gear. Does it still squeal?

 

[seicentoowner]

Yes it does it in gear and in neutral. as soon as the revs increase it starts and doesn't stop untill the revs drop to just above tickover, so i can drive it but can't get anywhere in a hurry or tackle any hills, think it might be time for a newer fiat. when i next post on here i'll have fixed it or bought a panda. in which case i'll put the 1999seicentoSX up on here as spare or repair.

sei sx has wet shaft box, so split cv boot means all the oil escapes from the box.. super easy fix and a cv boot is cheap - do that and then refill the box, sorted.

running with the aux belt does eliminate screech from alternator bearings and slack belt but the water-pump is driven off the timing belt so doesn't eliminate that, and it could also be the timing belt tensioner. Does it make the noise all the time and the pitch go up and down with engine speed? If so i would say its the timing belt tensioner. Again easy fix, cheap and easy diy job. Common sense dictates that you swap the belt and not just hte tensioner and also water-pump at the same time. May as well stick a new aux belt on at the same time for the sake of a few quid.

With the rocker gasket you need to just apply a small amount of sealant in the corners arounds the cam and not over tighten the cover down or it will just leak again... They have always been a pain in the arse and sometimes takes a few attempts to get it to seal nicely.

Once you done all that you can clean up the bay and get rid of all the nasty oil thats got everywhere and everything will be tickety-boo. I know cars can be annoying but try and remember cento's are good cars, they just have often had a very hard life with poor maintenance - once you gone through things and keep on top of the servicing they are very very reliable!
