hello again,

the current value would obviously vary depending upon the relay used. i assumed...(forget that).

from the above site mentioned "The current draw by the coil of a bosch relay is ~0.160 amps (~75 ohm coil)."

Measure the coil resistance with a multimeter, then 12 divided by that measurement will be the current.

Always check info with a digital multimeter.

I promise to be good.
