Ford Escort Berlina Start

If after you installed the battery you did not connect the ignition switch very possibly the ECU of your car is not damaged and the starter engine does not think it is suffered from damage. The smoke you saw was sure of the alternator's diodes bridge in the event that your car did not have a fuse cable in the alternator's feeding line ... Revise the cable that goes from the alternator to the positive pole of the battery in case it has burned parts and if you can check its continuity if the fuse is burned I think that with replacing it it would already be solved your problem, but you have to change the rectifier bridge of your alternator.
The ECU is protected by diode against the reverse tension
do not use the battery again when the polarity invests

Hello, look before saying anything, I do not think they are caused any type of damage, the cables are relatively thick and the smoke that came out of the heat of them, prove with another vateria in good condition connects well and starts it, if it does not part and does nothing, write again if it makes any noise or something you notify me, put another battery not the same so that you do you,

Hello everyone again, after this wait, I have been able to spend some time to the car, the truth that I have walked a little, I wanted to thank you for the time you have taken and forgive for the wait.

Well buy a new battery, install it in the car and start perfectly.

The Haynes Workshop Manual says it can carry the following batteries.

270 A / 50 RC
360 A / 60 RC
500 A / 70 RC
590 A / 90 RC
650 A / 130 RC

is car brought the following battery 275 A / 60 AH 12V.

I went to Carrerfour to buy the battery, according to his manual I could put the following

the brand number Carrfour = 540 A / 60 AH / 12 V. for € 71

and the brand number 1 = 480 A / 45 AH / 12V. For € 42.90

later they had the brand Varta but that left the budget, as I all have the pocket throwing smoke!

In the end I took the most economical that of € 42.90, they told me that I had 15 days to try it I have to seal the guarantee, return it or change it. In the end I do not know if it will endure without being discharged since the car is Berlina type with electric windows. Well I think that if in the 15 days it is not downloaded while using it for good and that it is enough for the car.

Well greeting everyone and thanks for your indications.
