So I am putting a Batt relay on my plane and it is one that grounds out

complete the circuit. Is it normal to have it get hot. Not to hot to

touch
but pretty hot.

Other's (sic) have weighed in with concerns that you may wrongly be
using a starter solenoid. They normally are grounded... and you
supply it with battery voltage.


For a relay to work, it is grounded. Matter of practicality. Otherwise
how would you complete the circuit?


OTOH...
What you describe that requires grounding to function, sounds
exactly like a bona fide batt relay and they do get quite warm....
but not so hot as to give your finger a blister.


When you run current through a wire coil and complete a circuit, in this
case an electromagnet contactor, a by-product is heat. Resistors make
heat. Unavoidable.
