Hunday Santa Fe, 2003, fails when sometimes starting

Please if someone can advise me, the honday Santa Fe sometimes to start, especially in cold fails, as if it were the contact, or does not make any noise, or the noise is like a Clap, Clap, and when you repeat several times the contact ahead and behind at the end ends up starting. I don't know if it's from contact or starter engine. I hope someone who can help me.

The problem is the starter engine, it could be the selonoid that the contacts no longer serve and it is the reason for the clac clac or the coals no longer serves, also with a test lamp you can verify the terminal 50 q is the thin line that controls the solenoid, you will need that someone turns the key to starting position and your measures if 12 V positive arrives

100 x 100 according to Ntrapero

Thank you very much, now I will see if I can fix it, I will first have to look for where the starter engine is, if someone has a mechanics manual in this car, I thank you,
I repeat, thanks for answering so soon.
