Ok, with all my fuses out and all my relays out I still have the drain. Started pulling connectors and found my drain goes away when both the "B" and "E" connectors have been pulled. Interesting they both must be pulled to stop the drain. I looked over the schematics and from what I see connector B has ties with the light switch and E has ties with blinker and hazard lights.

The investigation continues.

And I see some of you are plane guys....I'm currently building a Vans RV-4

There is a common failure of the light that goes up the pax side A pillar to the courtesy light in the top front. Seems the insulator fails. Let me look at the wiring and I'll get back to you.

RV-4. How original Should have built a Sonex.

j/k, RVs are good planes.

Plug B and E back in, locate the Emer flasher switch on the dash. Access the back of the emer flasher and remove the connector from it. check the draw. If that is not it, locate the light switch on the dash, access the rear of that, and pull the connector off the back of the light switch. Check the draw. If that's not it, locate the ignition switch, access the back of that, and pull the connector off the ignition switch.

These circuits served by the B and E connectors, and several of them are unfused.

Fuse buddy seems like a great idea, I've had one for a year or two though and not used it as its only for circuits with a blade fuse, and the drains most of us have seem more weird.
