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: http://www.components.omron.com/components/web/PDFLIB.nsf/0/39018354E59A56C985257201007DD68C/$file/G8JN_0607.pdf 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 think they were Bosch.

A handy source. I would have to check, but I bet NAPA sells the identical part for less $$?? Paul ======= At 06:19 AM 2/11/2010, you wrote: > >Both Digikey and Mouser have diodes and relays.

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.

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.
