my brother is riding my 2007 synergy turbo phazer, he say he rode it and it and shut it down for lunch, then went to fire it up and code 43 came on, sled wont turn over like that. he disconnected the battery and connected it again so sled ran for a hour then shut off.
I have told him to check all wires and connections, check battery wires and ground wires for corrosion. he hasnt found much. thursday i am going to look, any ideas for me to start looking??? is there any ground wires i dont know about hidden on the sled? i know of the yellow one on the right side of sled. the code info for 43 also says ecm could be screwed, anyone had this problem?

From the Tech Manual : "Fuel System Monitoring Voltage. ECU is unable to monitor the battery voltage (open or short in the line to the ECU)" So, ...
There is a fuel system fuse. Check all fuses for intermittentcy and/or loose connection in sockets.
From the fuel system fuse, there is a R/G wire going to the Fuel System relay. This wire could be chaffed and shorted.
At the Key Switch there is a B/W wire going to the Fuel System Relay. The connection to the switch could be loose or the wire could be chaffed between the switch and relay.
The Fuel System Relay and/or the connections to it could be bad/loose or shorted from water intrusion.
The wires to the ECU from the Relay could be chaffed and shorting into another component. (R/L and L/R wires between relay and ECU)
The connection at the ECU could be loose or shorted due to water intrusion.

Just a few places to start based on the E-Schematic. I always start with the simple stuff first. Good Luck!

I had the same type of problem out on the land and it was a real pain in the @$$ when my sled would not start out in the middle of nowhere !!! I managed to wiggle and play with the wiring harness between the oil resivior and the rad and it eventually started but there has to be something fishy in the harness in that area ???

Is there a ground wire in that area ???

ANYONE ???

Still wondering if anyone can shed some light on this subject ??? Maybe there is a diff. place where I can post my question ??? please help fellow Yamaheads ???

If you are looking for a ground wire, how about you open the hood and do some testing with an ohm meter? Zero ohms is a good bet that you have found a path to ground.
While you are in there, look for chaffed wires, if you think you are getting an intermittent short to ground. Wiggling wires to solve a problem is a symptom of either a chaffed wire or a loose connection. So you may also look at the connectors in that area to ensure they are making a good contact. If the sled is running, you can measure across the connector. If you see any significant voltage, it is a bad connection. No voltage across a connector = good connection. You can slip in the probes of the VOM in on the backsides of the connector halfs. If you have large probes, you can usually slip a small solid wire in there, and then put the probe on the small wire.
Also, these relays are susceptible to water intrusion. If the relay works after tapping it or warming it up when it is freezing outside, you probably have a bad relay.

wow, that is some good info to start with there Len. I personally don't know if it is a ground wire or a loose connection. the relays you mentioned , are they behind the battery and in front of the chaincase ??? when checking the connection, I am looking for no voltage as that = a good connection ??? Can you explaine the ground wire solution once again, just want to be sure. 0 olms means you have found a good ground wire or a bad ground wire ??? I really apprieciate you taking time to write to me as it took a couple of ancey days always checking my post to see if anyone has responded. Once again, thank you Len !!!

So I have one of those repair manuels disks and I was looking and brousing through it and came across what is called the "Diagnostic Mode". The fault code that gave me an issue is code 43, Now from what I understand if you go into the diagnostic mode and enter the corrisponding "diagnostic code 09" for the fault code 43. What results from completeing this procedure ??? Is the memory erased ???

Zero ohms when measuring a wire, with the other test lead on ground, = a good ground.
There are several relays in several locations. It would be best for you to have a service manual in hand, if you are messing with electrical components. The Service Manual will tell you where each relay is.
