Hello, New member here. Glad to have found this site. So my 2008 DF300 goes into fail safe mode. It only happens when the throotle is put all the way down. The buzzer sounds and the tach shows "ck control unit comm" and code 7-5.
This started happening after the PTT switch on the remote throttle would not trim up the motor. Put in a new PTT switch, didnt work. ck'd wiring from switch and found loss of power near the main PIN connector. Instead of replacing the harness I just ran a new wire. Trim works now... I didnt know if my current issue is related to the scabbed trim wire so I Cut the new scabbed wire and it is still happening... The famous white wire seems to have a good connection and the engine runs great otherwise.
When it goes into fail safe mode the engine still runs but the wont move forward or reverse until i turn the key off and let it sit for a minute than restart and it's ok. This only happens when the trhottle lever is almost bottomed out forward. Ive had the boat for three years now and i have dropped the throttle all the way down lots of times and it has never done this before.
I have also done a recongig on the engine thru the tach, still happens...
If I had to guess by the way this is occuring I would say the Throttle position sensor but I think the 7-5 code is drive by wire. Seems the computer thinks the throttle is moving to far forward (out of range)??
any help would be greatly appreciated. Thanks, Jeff
