Scan results....need help
 

This is from my one motor that is giving me the 2-beep soft alarm. Can anyone look it over and give me an idea what to look for? I did recently change my broken shift cable ... and it started 2 runs after that cable was changed..

Re: Scan results....need help
 

BTW, before the beeps, I did have a bad seawater impeller that did result in an alarm of overheat...that impeller was changed and ran fine until the cable broke. If there is a code indicating overheating, that was when the impeller was bad and was probably in the code history. But that was fixed.

Re: Scan results....need help
 

You are running in guardian-90 %-since you didnt give specs on the boat -you have codes indicating that you have issues with your transom harness-If you arent using transom harness than the codes that you get for pitot,steering and trim are normal codes and they will always show up on code history-however the reason you are being limited to 90 % and running in guardian is that you have a code for seawater pump circuit high

Re: Scan results....need help
 

you should check all connections at sea water pump and look at the connection good-also I dont know what type of boat you are running but by the looks of things you have more run time 1500 to 2900 rpm's that at any other rpm range-did you buy this boat to idle around or are you gonna start running with the dogs!! jam the throttles forward brother or could it be the boats tooooooooo fast for ya??

Re: Scan results....need help
 

SEA PUMP CKT HI

Thats the one thats causing your alarm. CKT HI is usually due to open circuit. Start by checking the connector at the sensor for bent pins, water, ect.

Dave

Re: Scan results....need help
 

I don't see any evidence of "trouble with the transom harness".

Re: Scan results....need help
 

Dave, are you talking about the sensor attached to the pump housing that senses water temperature? If so, I know what to look for.

Oh, and is the motor in the 90% Guardian mode? if so, can I erase the fault codes to get it back to 100%?

Thanks much!!
Jeff

Re: Scan results....need help
 

Damn - I guess swimming is out of the question ! :eek: :D

Just making a funny. Sorry - carry on.

Re: Scan results....need help
 

The sensor on the pump is the Sea Water Pressure Sensor. Thats the one you want to check.

Yes, you are at 90% available power, but you can't just clear the code. A fault code that is "Active" is due to the sensor being currently out of range. Even if you could clear it, the fault would reset immediately.

Dave

Re: Scan results....need help
 

Sounds to me like the engine is going bad. I'll give you $50 and take the problems away tonight. :evilb:

Re: Scan results....need help
 

LOL, how are you and Deanna?

Heading to the river this weekend for probably our last trip out there this year. Have a safe and fun labor day weekend.

Re: Scan results....need help
 

Maybe you ought to slap some big ol carbs on them motors and that will get rid of all those silly codes.

By the way just in case you forgot, I still have'nt seen the boat.

Re: Scan results....need help
 

Problem found!

Pressure sensor clip was broke and fitting was open enough to get moisture inside the connections and corrode. I cleaned it out and tested, all OK. Now all I need to do is get a new sensor and put back together.

Thanks to all!

Hey Ron and Cord ....

i like happy endings

Re: Scan results....need help
 

DIACOM SW is pretty nice! Takes the guesswork out.

Re: Scan results....need help
 

u still have one problem-the fact that you arent running the boat like it should be run wot bumpin the rev limiter-

Re: Scan results....need help
 

"Sea Pump Pressure 43.46 PSI"

This one jumped right out... 43.46 lbs at idle :eek:
Got to love the Diacom :drink:

Re: Scan results....need help
 

That's a nice looking boat Jeff, but I would prefer a beer and a tour, then again I'll buy you a beer if you ever get that thing off of the river and out on the big pond. :drink:

Re: Scan results....need help
 

Guess I've had my head in the sand...when did you upgrade to a Sonic?

Deanna and I have been good. This last year has turned around 180 degrees for us. We are both working way too many hours. Gonna have to force some time off before something breaks.

Re: Scan results....need help
 

Hp500

Sounds like same thing that happened to me,had a seawater impeller fail and shortly after that the 2 alarm trouble started..
I`ll double check that sensor on the pump...did u replace yours and how much was it?
tnx

Re: Scan results....need help
 

Local dealer was out of stock so I cleaned terminals as best I could and rigged a clip to get me on the water last weekend. It worked for about 80% of the trip then started up again. I am replacing the sensor and wire assy. Make sure you are careful taking the molex plug apart so that you do not break the plastic clip. Once I opened the molex, you could see the female ends corroded. I then removed the sensor from the pump and those too were corroded. It is very difficult to get in there and clean the terminals without opening up the spring terminals on the female end. I think that is what happened to me when I tried to clean them.

Re: Scan results....need help
 

Thats definitly the problem, as soon as I disconnected that sensor the 2 alarms started up...The connector looked fine ,however...I`ll have to wait and see if alarms come back before I buy a new sensor.
