Re: ECM for 2001 Z150TXRZ 2001 150 hp HPDI
Thank You! I should have looked more closely at the wiring diagram.
I checked to see that there is 12 volts to the relay, then I tried swapping the relays, and still virtually no current to the coils. Next, I took apart the fuse assembly and checked for continuity between the relay output side and the pins on the back. I only have continuity to pins 19 20 21 and 24 all R/W on the bottom row. No continuity to any R/Y pins which leads me to believe that intenal corrosion may have severed the connection to the top row of pins. I am going to replace the fuse assembly.
From previous posts, some may know that this is a "project" boat that I have been tinkering on in my spare time off and on for several months. It has been swamped twice. (First time they left the plug out when it was launched for the season, the next year a loose damaged grounding block caused leakage that was not noticed ) The first time, insurance paid around $8,000 for new engine electronic components , the second time a guy that worked at the Yamaha dealership bought it and had a Yamaha tech friend work on it. After spending around $800 they had a falling out. I bought the boat this spring. I have no illusions, and am working on it for fun and education. When and if I get it running I will post all of the gory details. It's a nice 22' center console Aquasport.
I have found the information on this forum to be extremely helpful!
