Hi guys, hope you all doing well.

Yesterday I heard something about this and I am hoping someone can explain what is it and how to fix it if it exists in my Punto mk2b.

Car battery technician told me that there are two possible "things" that are draining cars battery while the car is parked at home(or in garage).

He called first one, surface electricity draw/drain.
What it is is, if you take out your cars battery out of the car, you take a multi-meter and you put positive lead on positive terminal, and then you put negative lead onto plastic part of cars battery, you will notice that "something" is draining your cars battery because multi-meter will show a value of 1-2 volts, or even higher.
The solution is to simply take the battery and clean it from dust/dirt/grease and clean its terminals.

Another way your battery can be drained, as he called it, is from "parasite draw/drain".
Supposedly this is because of manufacturers mistake.

In Fiat Punto(he did not say exactly which model or mark) there exists both parasite and surface electricity draw on dashboard.
Electricity draw is between 0.7-1.4 v and also more than 1 amp until this issue is fixed.
And to solve this you simply use a resistor.



My questions are, does anyone know about this and is it present on my mk2b Fiat Punto 2005 ?
And is there a webpage where I can read more about this issue and how to fix it exactly ? Like, where to install this resistor, its values etc. ?

If you have a 1 amp draw from the battery with everything turned off it means something isn't working right on your and not turning off correctly and you need to find out

Fitting a resistor is not the correct fix for this it's simply hiding the issue

You have a computerised car so it is never completely turned off and you cannot leave the car for long periods of time without the battery going flat. There is no fix such as a resistor to help you. You can buy a high current switch to disconnect the battery. A damaged alternator can drain a battery because it is never disconnected from the battery - you have a big fat positive wire going to the alternator engine side and a big fat wire going to the fuse box. If you disconnect the engine side and the problem goes away suspect the alternator needs replacing.
 
Hey guys thanks for answering but I do not think I have this problem, I came here looking for some knowledge on this topic, thats all.

You cannot solve your problem by fitting a resistor.

Batteries do go flat when not connected to anything but this takes months not days.

Lots of people have tried to help you with their posts and suggestions.

Good luck

Battery casings are made of
'Non.conductive materials'

They are plastic for a reason ;)

I have a small diesel that covers minimal miles.. TEN miles in 6 months :eek:

The battery still starts the car.. (y)


The quoted losses sound HUGE ..!!
Battery power would not last 1 day.. nevermind 100 :p
