CLIO 2002 1.4 16V electronics problem

After welding the chassis with the disconnected battery and the injection calculator disconnected. The windshield wiper is not always working since you put the contact pilot-the breakdown pilot marks a failure and for which the car does not start. I consider the key and start connecting another car but the other has to be torn off so that it has to enter it and so you have to enter the contact Problems but the clean continue to fail and the box and the computer without working
I have also realized that the radio screen is a bit on for which the batteriun scan R that left me did not mark any error but only checked the calculator and not lauch and nothing else

mmmm ta peluo I that you disconnect the battery from the negative terminal about 30 seconds, and then you connect and close the contact Barias Beses and you start having what happens, now I recommend checking you the connection of the terminals and even more of the negative that goes down with another cable to the chassis on occasions when disconnecting the terminal chassis or motor to motor and see.

I have already tried all that since I have to leave the battery removed because it spends it as
I have also tested with the mass cables and with the voltimeter to know if there is a mass loss at any point
this is to go crazy since we all mislead

Hey and if you disconnect the computer again to check that there are no folded pins and that they make good blowout

I have not tried it but keep in mind that all that worked perfectly until the chassis was deaf
