So I am putting a Batt relay on my plane and it is one that grounds out to
complete the circuit. Is it normal to have it get hot. Not to hot to touch

Could be a 'starter' relay.
That kind is intended for non-continuous duty.

But hard to guess trying to feel the screen...

If I recall correctly and it's been about 15 years since I
built the RV-6... The Master Relay actuates by grounding a
lead. The Start Relay actuates by applying 12 DC positive
to the relay.

The Master is intended for continuous operation while the
Start is only for intermittent operation.

I don't recall the Master Relay getting hot but, then, I
didn't ever attempt to touch it after the engine was
operating...
