If you examine the housing at the base of the terminals, I think you will see a letter "I" on the left one, and I forget what's usually on the right one . . . an "S" perhaps? In any case, the I terminal is used for your 'stuck starter' light (optional) and the starter push button delivers power to the right terminal. The diode (1N540X series) installs as shown . . . with terminals of course . . . never wrap wires around threaded posts in an airplane.

Found them!!! As in the picture Bob sent...the S and I letters are on the downward facing boss under the terminals. I could not see them from above and I had to remove some components and sneak up on them from underneath to be able to read them...I could not even get my head wedged in there so I could see them with my glasses on so I had to wedge my phone in there to make a picture (I use this same picture taking technique to read menus at restaurants nowadays). Bob, it looks like that is the same solenoid that I have. Do you have a manufacturer and part number for that unit? The next important question I have is...on my installation the big post on the left is the powered bus and the big post on the right is the post that gets wired to the starter motor...Since the S post is on the right side that would lead me to believe that the big post on the right should be the powered bus...does it really matter what big post goes to what??? -----Original Message----- From: owner-aeroelectric-list-server@matronics.com On Behalf Of user9253 Sent: Wednesday, October 9, 2019 6:31 PM Subject: AeroElectric-List: Re: Does Anyone Recognize This Starter Solenoid???

I would power each injector from its own fuse off the battery bus. The injectors are powered down any time power is off the ECU . . . no need to make battery power crew controlled. The fusible links serve no purpose.

It does not discuss the most common cause of decreased capacity. I didn't search for the discussion, but recall quite a bit about folks on Vans Air Force experiencing very short life, say under 2 yrs, with Odyssey batteries from using maintainers that were not optimized for AGM batteries.

I'm using two batteries and I have two battery buses with an injector bus connected to both with diodes. I do show the injector bus crew controlled from both battery buses because that allows preflight checking whether the diodes are shorted or open. I show the diodes in parallel pairs because they come two to a case and I don't know whether or not there is a failure mode that could open both at the same time. To explain what the injector relays are... they switch the injectors to the backup ECU in case of primary ECU failure. Schematic attached. -------- John Bright, RV-6A 25088, at FWF O-360, 8.5:1, vert sump, dual SDSEFI EM-5-F Z-14 modified for EFI Newport News, Va Read this topic online here: http://forums.matronics.com/viewtopic.php?p=491755#491755 Attachments: http://forums.matronics.com//files/erase_451.jpg ________________________________ Message 16 ____________________________________ Time: 06:26:23 PM PST US Subject: AeroElectric-List: Re: fusible link downstream of circuit breaker From: "user9253" Whenever fuses are connected in series, there is a chance that both could blow. Consider increasing the 15 amp fuses to 20 or 30 amps. -------- Joe Gores Read this topic online here: http://forums.matronics.com/viewtopic.php?p=491761#491761 ------------------------------------------------------------------------------------- Other Matronics Email List Services ------------------------------------------------------------------------------------- Post A New Message aeroelectric-list@matronics.com UN/SUBSCRIBE http://www.matronics.com/subscription List FAQ http://www.matronics.com/FAQ/AeroElectric-List.htm Web Forum Interface To Lists http://forums.matronics.com Matronics List Wiki http://wiki.matronics.com Full Archive Search Engine http://www.matronics.com/search 7-Day List Browse http://www.matronics.com/browse/aeroelectric-list Browse Digests http://www.matronics.com/digest/aeroelectric-list Browse Other Lists http://www.matronics.com/browse Live Online Chat! http://www.matronics.com/chat Archive Downloading http://www.matronics.com/archives Photo Share http://www.matronics.com/photoshare Other Email Lists http://www.matronics.com/emaillists Contributions http://www.matronics.com/contribution ------------------------------------------------------------------------------------- These Email List Services are sponsored solely by Matronics and through the generous Contributions of its members.
