Both Digikey and Mouser have diodes and relays. Search their websites for this
part number: G8JN-1C6T-F-DC12 made by Omron. It has a metal one-hole mounting
bracket and is weather proof. Here is the data sheet:

I thought it interesting that the normally open contacts have a higher current
rating than the normally closed contacts, maybe because magnetism closes contacts
quicker and tighter with less bounce than a spring does.

I got mine from Waytek. I think they were Bosch.

Ford uses N2 filled, diode internal relays used for the glow plugs. A
handy source. I would have to check, but I bet NAPA sells the
identical part for less $$??

Here's what I'm using: Digikey 255-2161-ND
They have the built-in resistors.
Standard automotive type. Not having to wire in the diodes/resistors is a
big bonus. Also, the coils are polarity insensitive when using resistors
rather than diodes, if that matters.

Had an interesting discovery today. I was charging the battery on my
RV-7A and had the Master on and the Dynon Flt-Dek 180 on while I was
doing some calibrations. When I got out of the airplane I felt the
alternator an it was warm to the touch. When I turned the Master and
Dynon off it soon dropped to ambient temp. Do I have something wrong in
my wiring? Or would this be normally expected given the circumstances
described. I have wired the plane in accordance with the Z-13 diagram
but have the internally regulated alternator until I need to change it.
