Can't get simple electric relay to work

[AKD]

I moved all my electrics in my boat to a relay so they wouldn't continuously drain the battery as soon as a I spawned in or if I turned the boat off. The original setup was Battery --> Electric A and Ignition Key, Electric B --> all other electrics. Ignition on/off logic was then connected electric relay on/off. This didn't work and battery was draining at spawn in, lights could be turned on / off, etc. Tried rewiring the logic to a on/off flip switch (electricity directly from battery again) thinking maybe the keyed ignition doesn't work as a simple on / off and still have same issue. I also tried including an electrical connection from Relay Electric A to Electric B just in case they needed to be connected for some reason and still no joy. This seems like a super simple setup, but I can't figure out why it's not working. I must be missing something obvious here.

I've personally not seen relays drain batteries, or just engines either (though i've less experience with modular engines' power drain).

I know there is a little bit of power drain if it's a wheeled vehicle, as any wheel motion that's tied to the engine seems to somehow translate a little bit to electric drain, that's the only case that i can think of here.

Don't connect the A and B terminals as you're basically defeating the purpose of the relay (and circuit breakers too). The only thing I can think of is what happens to me when I use breakers (not much experience with relays, sorry). I often chain electric nodes to avoid a web of yellow lines running from every single device to the breaker. Often I'll accidentally chain one of the devices to a battery or one that leads to a battery down the chain, causing the circuit breaker to be bypassed for those concerned items.

Long story short, for the relay, make sure there is no ELECTRIC connection between your key and relay or any other connection(s) going from the ignition (and battery) to another device. Also make sure you are using the logic node directly from the key ignition to the relay, without any NOT blocks etc.

i dont build relays, but i build boats and rockets and plane

Well, had to rebuild the electrics entirely, but got it working. Also added an OR block fed from both ignition and a master electric switch, so I can either just fire it up and go and shut down completely using the ignition, or if I want to shut down engine and keep electrics on, I have that option also. Thanks for the help, even if the answer was start over from the beginning. I suspect that I had either the alternator and / or generator feeding into relay B instead of directly into battery and this was causing issues.
