Hi,
my tempra accumulator will be empty after few km drive. I have changed charger without results. There is still red light lighting on my cabin to indicate that there is something wrong with charger. Is there some systematic way to study whats wrong? Do I have to change some cables or is there some place what is worth to check first. Do I have to buy new accumulator? Help!

Kind Regards,
Marko

Did you check the voltage between accumulator terminals? It must be about 13-14 V when your engine is on. If it's lower - check your connections.
Did the old generator was damaged? Your new generator - is it new, or recycled?
 
Voltage is between 7-10V when lights is on. Today I try to check and clean connections without results. Tomorrow I will check ground connections (pictures). There seems to be a lot of rustiness. New generator is recycled.

ok, no results after cleaning ground connections. Next step is to buy new accumulator....?
 
If your battery light is glowing, then it is probably something wrong with the alternator. Maybe a diode shortcircuet or a regulator malfunctioned. I think that is the couse of the problem. New acumulator won't solve anything. Just connect the old-one on a recharger. As for alternator, if charging works, the voltage (when car is running) should be 14.0 -14.6V. On my Tipo 1.4ie was once that kind of problem. Warning light was on and I drived for 2 days like that. Suddenly, headlamps went off and few seconds later, ignition system shuted down. Just remember, warning light does not apear for empty acumulator, it apears for false charging system. It is possible, that your "recycled" alternator is false, or it has a false regulator.

Hi, I just buy new accumulator and nothing changed. Charger light is still glowing. So, I measured voltage values right on charger. There is connection named D+ and B+.
D+ gives 6.5 - 7.5V and B+ value is about 11.4V. I don't know what this mean? If I understand right, normally B+ and D+ value must be almost same? Maybe next step is to change regulator?
 
Regulator is installed on alternator. They aren't so expensive. On the other side, entire alternator is very expensive. If you are an electrician, just measure diodes first. If one of them is shortcircuet (if electric current goes both ways) you have a winner. In that case, you only have to replace diod panel. You can do that with a simple ohm/voltmeter, which has a function for measuring diodes. If you get a sound from your meter, diode is broken. Regulator can also be measured. If diodes are ok, and coil is ok, then it must be regulator. I'm not sure for regulator, what values should it display, but changing it won't be so expensive (it's a little white box on alternator). If you don't know how to measure values, simply go to a local mechanic or an auto-electrican. He will solve you problem in no time.

Good luck
 
In my old alternator I changed regulator and coil. At the same time I measured diode brige and everythin seems to be ok. Here is some picture from old alternator (picture 9-11) : http://www.pasilankaista.com/~ekqvistmt/FIAT/?AUTOMERKIT:Fiat:Kuvia

After that I have changed alternator (recycled) and seller gives me quarantee. I think that easiest way is to aske them to deliver new (recycled) alternator.

Yesterday I found something odd and just now I cannot say if it depends on all this powerloss problem. Here is some picture of this what I found:

In picture 6 you can see couble of cable that comes from cable bunch. One of this cable is some kind of sensor cable, and is connected to engine (picture10). But the other one was broken cable. Today I try to find out what it is.
 
today I made lamptest (5W lamp). I connect lamp between D+ and accumulator + . Start the motor and measured following values. After I started motor. testlamp offed. Maybe glowing little bit.

- between alternator body and B+ 14.5V :))
- between accumulator 11.4V :confused:

- between D+ and ground 9.5V

So, is that test proved that alternator is ok. But there is something wrong with grounding because accumulator gives only 11.4V?

..today I made also current loss test. I need to know is the problem - or + side.

plus side:
I measured voltage between accumulator + and alternator b+. Result: 0,12V

minus side:
I tested - side by measuring voltage between alternator body and accumulator -. Result: 0,00V.

What I have to do next? :confused:
 
Alternator problem is solved. I changed the regulator and everything is ok now. Thanks for your help and support. 'death_paladin9' your guess right about what's wrong with my alternator problem. Thanks for you help.
