Need new batteries? Going from 12V to 18V or 6V to 12V? Wiring Questions?

hey, would a relay cause a parasitic drain? Im currently reading 0.15 amp when doing battery drain test with the connect switch off. Once I disconnect the relay, it goes to 0.0.

Relay is connected to a 2V 3A Car Blue LED Light Power Metal Push Button Toggle Switch that would power a small car radio when switched ON (only thing connected to relay) . I have disconnected power cable from radio to test, and still getting same amp drawn with switch off, I have also tested by removing the relay and amp usage goes to 0. Is this normal, or do i have a faulty relay?

thanks

A relay should not draw any current unless the coil is connected to both +12v and Ground. Not that I'm aware of anyway.

If you can figure out which relay is causing the draw you can try a new relay there and/or troubleshoot down the lines connected to that relay.
