Emacs!
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.

The banded end of arc suppression diodes always connects to positive.
For this contactor, connect the banded end to the small terminal that gets
positive voltage from the start switch. Connect the other end of the diode
to ground.

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???

| Subject: | fusible link downstream of circuit breaker |
One of the electronic fuel injection systems marketed to EAB delivers a harness
with fusible links inside a firewall passthru connector. I sketched what they
recommend and attached it here.
I see:
* The unprotected wire between the essential bus and the circuit breaker.
* The possibility of the wire between the breaker and the firewall connector opening
or shorting to ground taking out all four injectors.
But I'm wondering if the fusible links do anything at all. I don't know the awg
of the links but suppose they were 24 awg which has a fusing current of 29 A.
If an injector wire shorted to ground between the firewall connector and an individual
injector would the circuit breaker trip taking out all four injectors?

That document doesn't say anything about being "kept near full charge
without much draw down". It refers to batteries NOT being kept or recharged
full.

The starter will work either way. However, the indicator light could remain on
if wired backwards, depending on the internal connections.

Do you have some pictures of the insides of some start solenoids?=C2-

Go to an auto parts store and if it looks
like that one, it will work. That's
one of those exceedingly generic parts
by probably hundreds of manufacturers.
Here's one example that claims to be
"heavy duty" truck-rated. $8.50 delivered
to your door . . .

The 'fat" terminals are interchangeable.

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.

Yes that is the document for reconditioning. 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.

Thanks Bob,
My plan is to fuse the injectors individually at the bus as you suggest. 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.

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.
