I have a 2007 Sea Ray Amberjack with a Kohler 5ECD which is shutting off after 15 seconds running with a CO 3 code.
I ordered a new CO sensor module (GM46362) I installed it and started the generator. Within 15 seconds of runtime it shut down and flashed the CO-3 as it did prior to installation of the new sensor module.
The generator is a 5ECD Serial number: 2102205 with 85.1 total hours.
The following trouble shooting has been conducted:
1. Verified the Cabin CO sensor is stand alone and not wired to the generator for automatic shutdown.
2. Verified continuity on wiring from P1-15 on the ADC to P40-1 on CO sensor.
3. Verified Controller Configuration was correct per TP-6391 as follows:
a. System Voltage = Uu00
b. Unit Configuration = Uc00
c. Engine type = Ec04
d. Engine data input = Ed00
e. Battery Voltage = Bt12
f. Communications = Cn02
I had pulled the generator out of the boat due to LOC an UU error codes. The fuel module was completely corroded from salt water intrusion and the exhaust manifold water outlet slots were completely clogged. I replaced both fuel pumps, the exhaust manifold (new version with larger slots), all rubber hoses and O-rings, all fuse holders and fuses, spark plugs (NGK BPR4ES), and wires, impeller and sent the fuel injector out for cleaning. I ran the generator out of the boat using a fresh gas can as fuel supply and it ran great for 20 minutes but had a small leak around the new neck I had installed in the exhaust manifold. I resealed the threads on the neck and when I ran it again it started throwing the CO 3 code. According to the TP 6391 manual I have this is a communication error. ‘Shutdown occurs if communication is lost between the CO sensor and the ADC”. I then grounded the P1-15 wire from the ADC 2100 controller in an attempt to bypass the CO module to no avail. Thinking it was perhaps a bad new CO sensor the parts place I purchased it from sent me a new one. Same result of shutdown with CO 3 code.
I subsequently installed a brand new injector as I had read of an occurrence with a correlation to a clogged injector. The generator continues to run for 15 seconds and shut down with the CO 3 code. The generator starts on the first crank and runs smoothly with no apparent miss or rough idle prior to shutting down. No smoke out the exhaust either. My hope was this is not a faulty ADC 2100 controller ($1200) dollars. Have a hard time thinking that would be it due to the fact all of the other functions of the controller seem to work but it is an electronic component so assume it could be possible.
Is there anyway to confirm this is indeed an ADC 2100 controller issue vs. ECM or other component?
