I checked back the docs and yes for this engine

Hello,
I solved 2 issues today :)
First one: slave solenoid issue
when we turned the contact key to start the engine
there is +12V to the slave solenoid
Ground is also ok
we were able to crank with a direct cnx of slave contacts
so it confirms what was already suspected --> slave solenoid must...
sorry I check back the full electrical sheme from ECM555 doc
I followed each grey wire from commun slice101 and
there is one connection to ECM pin 18 !
then I can first disconnect ECM connector and check if +5v is correct
otherwise ECM is bad :-(
will take you informed ;-)
Hello,
stresspoint:
battery voltage is 12.90v
when I do a direct connection of slave connections
engine is cranking correctly and I can try several times
so battery seems correct and I tried with 2 different

Hello,
For QBhoy:
sorry seems I didn't received an email about your post
then I saw it only when posting my last tests conclusion :-(
what do you mean by: "Give them a dunt"
to give a light hammer blow on them?

It was running last week end :-(
When I turn the key I only hear one "clac" on the slave solenoid

sorry AllDodge for the duplicate, I probably made a bad action when I post my previous answer :-(
QBhoy:
it can be also a root cause because the "professionnal" has done some
modification everywhere including this security as well :-(
thanks to the full electrical wiring diagram 4D-7 and other...
ok for the complete wiring diagram
that's fine now I didn't read it carefully because I tought it was only for ECM debuging but I found all components relative to ignition
that perfect and it should help us to check from point to point
many thanks for your help
don't worry if I don't give more...
sorry AllDodge, but what do you mean with: "Reposting the same question(s) is not allowed."
I don't understand
I saw it but didn't care about it because I tought it was the New York subway map :)
honnestly that's unreadeable and that's the first time I can see such kind of scheme :-(
I will...
Fun Times:
thanks for your help!
When I was looking for the right manual
I checked manuals titles after #18 and I found only #32 for 4.3 engine

I got it now and I will read it carefully because the extracts you attached
are really...
Hello
Alldodge:
that's my son's boat and I don't have access before few days
you will find attached the picture of the ignition coil 392-863704
for this engine model if it can help you to identify the exact type
in all Mercruiser manuals I never see such ignition coil in diagrams
only 2 wires...
Hello,
sorry for my english mistake, I'm French and I don't like translators... ;-)
I bought a boat having a Mercruiser 4.3 2003 with 6 cylinders
price was low because there is no ignition and I was aware of that
I don't know exactly what did the previous owner supposed
to be a "nautic...
