Dear Sir,

I would like to know, what all this connectors on Valeo alternator are for! Because I have connected alternator and I don`t know why 1 screw that I didn`t connect it is for? Also this screw is getting very hot when I turn lights on(load).
See attached picture.
10mm2 black wire goes direct to battery. 2,5mm2 black wire goes to ignition switch and it is connected direct when ignition is turned on to battery. 2,5mm2 Grey wire is connected to lamp. Other end of lamp goes on ignition switch when ignition swicth is on is connected to battery.

Please help me solve this problem.

Thank you!
