First of all, and thank you very much.
I have a astra g 2000 dt 100cv Y20dth year 2000
The address is last in an instant, it has liquid the fuses are fine, the battery witness does not turn on and the alternator is fine and I have decided to disassemble it to replace it.
Uuufff

The one that I am going through with disassembly, still I have a minimum problem and I do not know how to verify its operation.
It carries two thick red+ cables of the 80A fuse box. and brown dough in chassis. and the two -wire connector that gives the operation signal of the blue white alternator "+ I think". and black + low contact.
Could you help me check this pump on the battery and thus make sure that it is really the bomb that is broken?
I see in the electrical scheme that thick cables are clear red + and brown- Should the connector with two bilos black + low contact and blue white + alternator. Is this form of proof correct?
I try to send you images of the pump and scheme model.
As always a health and thank you very much
I have made the previous connection and nothing at all

.
If so, the test does not act.
Someone who can help me or advise.
As always a health and thank you very much.
