Title: 131 electrical issues!
Post by: mirafioriman on December 05, 2010, 07:30:10 PM
Decided my silver super should get a bit of TLC today.....

First up get the horn working. Turned out to be a bad connection on the horn ring behind the wheel.

Next the lights. Numerous bad connections sorted and a few bulbs replaced. All working except the passenger side front indicator unit which although being relatively new is suffering from a bad connection I was unable to sort today.

Finally I had a look at the central locking. Drivers door locking motor was seized and yes you've guessed it I broke it ::)

I did mean to take some photos but never quite got round to it.......

After fixing the front indicators I also intend to fit the front bumper correctly ;)

All the electrical problems in 131 have the same reason bad quality of electric connectors and bad cantact in  fusebox.
I have serious problem in the past with the fuse near the electric lock system PCB the fusebox does not make good contact with the fuse and i dont have ignition the best solution is to install new fusebox.
About the connectors in my opinion all of them needs to be replaced with new ones in my car i try to install waterproof if i can find.
The connector have pins inside these pins in 131 create on their surface a kind of "rust" who caused from high humidity or from the water when you wash the car and destroy the contact surfaces .The connectors in 131 does not have any protection in water or in humidity.
Also the switch of the electrical motors in windows it is better to "drive"the electric motor via contacts of relay not directly to the switch when the window mechansim blocks or can not lift the window easy(after many wears) between the contacts of the switch create spark and destroy the switch.

What you need is a can (or a few cans  ;)) of Ambersil's Amberlube electrical lubricant. It solves most (if not all) electrical problems on Fiat 131  ;D  http://www.stanleysonline.co.uk/product-1820.htm (http://www.stanleysonline.co.uk/product-1820.htm)

the best solution is to install new fusebox.
Do you know where to get a new one? I would like one very very much...
Last week I tryed to pass the car through the Control Check Center and the fuse which was for the radiators ventilator was burned... So the car went hot and ... I think you can figure out the rest ... :(
