Engine wiring schematic for 2007 SAN?

[Aebert2668]

Does anyone have an engine wiring schematic for a 2007 SAN 220?

Check out the Manuals & Brochures tab on this site. The engine manuals for 2007 are there and should have the wiring schemes.

What is needed is a wiring diagram for the ignition switch to the fuel pump and ECM. I have no power going to the switch side of the relay.

Not sure what you mean by ignition switch. You have a keypad, right? That just works relays in the breakerbox/pme. The breakerbox has a bunch of relays in it. I would go to this link and study the 2008 diagrams. Is it a purple wire going into a relay that does not have power? http://www.planetnautique.com/vb3/content.php?59

For example on the pme picture there is an ignition out at #5 purple. Probably same on 2007. You easily drop the kick panel and check for power to purple out of all the wires coming out of box. If you dont' have power you could have bad relay in the pme/breaker box. If you do have power at that point you can check for power per the main wiring diagram their is a connector pictured in upper right labeled engine connector that also has a purple ignition wire.

Anyways my point is that 2008 and a 2007 are probably not much different so study a pme wiring diagram and a main wiring diagram and you may be able to figure it out.

I have 1 hot and 2 grounds at the fuel pump relay the forth wire is the control power to energize the relay. it is supposed to be hot for 2.5 sec when the key is turned on and then is powered by the ECM when it sees RPM pulses . In automotive applications the circuit goes through the oil sender and will only supply power when the oil pressure is OK. I would love to have a complete wiring diagram from the keypad to the relays on the engine?

I think those 2 pictures available at the link are all there is. Keypad only talks to pme/relay box. Relay box goes to connectors to the engine. Maybe the 2.5 second is built into logic inside pme/relay box.

[Nautiquehunter]

I will look into the PME box there are three relays on the engine 1-fuel pump has no power to the activation term. 1-starter is working fine and 1- not sure but it appears to be working it cycles the throttle plate when the start button is pushed.

[scottb7]

I found this...Feeling this and other 2 documents at that link will solve the problem for you. Could still be few things. But it does show fuel pump relay control by ECM. Which leads me to believe I was wrong about 2.5 second built into pme. Must be built into ecm.

A great big THANK YOU to Scott . That looks like exactly what I need now I can test instead of guess.

Mike, I have the entire diagnostic manual if you need it, posted my email addy on CCF, file is too big to upload on either site.

[Aebert2668]

Scott can't thank you enough! Quinner, also thanks for the information. Hopefully, Mike can get me going so we can take a test ride after the polar vortex passes.

[Quinner]

hah, no sympathy on the V Tex, its snowing here in Chicago, boats winterized and the lake is ready to freeze, lol
Good luck on the fix and be sure and let us know the outcome!

[scottb7]

Yes, let us know what ended up being the problem. My boat has been gone to storage a couple weeks. But guess what? Tomorrow is season opener for snowboarding with friends. Game on!!!

[Aebert2668]

Guys, after much help from Mike, we finally decided it must be the ECM and took it to the dealer for a scan. So 1300.00 later, I have a boat that runs! I am grateful for all the help from Quinner, Scottb7, and especially Nautiquehunter. The only warning I had that anything might be going wrong was a "spark delivery" warning, shortly before the engine shut down. The previous owner had mentioned he had a lightning strike to his home, but the boat ran fine for many hours after and it may have just been coincidental. Not sure this will help anyone because of the rarity of an ECM going bad. Also, technically I have a 2006 SAN 220, the CC owners manual gives a confusing description for serial numbers and there is no mention or listing of a 220 at all in the 2006 owner's manuals online. Again, I appreciate all the help, now onto better projects!

Interesting that the manuals don't talk about the 220 in 2006. I'll dig up the proper manual and get it uploaded here. I know the 220 was released as a 2006 model for sure. Here's the press release!
