What should happen with the advantage that the motor relay was KZ?

Lord was recently a strange case, there's a constant + 12 volts(along the way, he still connected on the light, which works correctly), connecting wires to it, and the retractor relay, gave KZ.
If you connect directly to the battery, no fault, pulls and twists.
Unfortunately all apart and understand why this was not appropriate.
What version of this unknown shit?
Personally, I gave up after hours of thought and just made the 2nd wire from the plus purely for the retractor with a motor, worked.
The strange thing is that before with that plus everything worked and I would often refuse, and after all of the short-circuit issue.
By the way, SC wasn't always, it sometimes goes missing when he pulls out the connector from the retractor relay and reconnected back.

Don't know that there can sometimes be a plus, but the winding/relay engine and other until you store energy are copper wire, whose resistance can check the the usual ohmmeter and it is not particularly large.

If the retractor relay from the auto, it probably eats when you turn on the Amp 7-15, most conventional power supplies will naturally go into protection from this, the batteries in principle could afford it.

What kind of mythical "plus" what it's for?
permanent plus from ed. battery that the ignition key is - Ewell commented on June 27th 19 at 15:16
