well,
the voltage certainly depends on the relay-winding-ratio. I could not find any detailed specification for the resistance of solenoid of YH185B-Relais
They vary starting with 90 Ohm to 1100 Ohm.Maybe some member here can help with this information ?
By the way very useful analysis of the hairpin-circuit presented by Fred B

Hi Kator01,

Here is a data sheet for the YH185 relay series from its manufacturer:

http://www.yhrelays.com/e/upload/s6/fck/file/2013-05/YH185.pdf 

The YH185B relay type has a 90 Ohm coil resistance, for operating voltage at 12 V.

Hi Gyula.

As an additional note most of the automotive relays seem to have a resistor placed in parallel with the operating coil.

This is based upon my observations, having taken quite a few apart over the years.  :)

Cheers Graham.

Hi Graham,

Thanks for the additional information and yes (a resistor or a diode or a diode with resistor or none of them) may be found paralelled with the relay coil and this is mentioned in the data sheet at the ordering code explanation,  see attachment.   

Cheers

Hey Gyula,

thank you very much.

@grumage, thanks, did not know this.Maybe they put in the resistor to avoid excessive sparking which is what we actually want for this application

Hi Mike,
Well, I think the resistor is connected to the coil and not to the relay closing or opening contacts. 
Either in paralell with the coil or in series,  I think mainly in paralell, especially when a diode is used, this latter may be in series with the resistor and this series R - D combination would go in paralell with the coil, to tame the spikes at relay coil switch-offs.
