BPS attempted to fix it by reconnecting and re-calibration. I made a trip to Hartwell the first of March for my sons high school team to compete in the BASS High School open and had a authorized MK repair person look at. He replaced a magnetic sensor and soldered some wire in my foot pedal saying this would fix the issue. It did not fix the issue. In the meantime I have developed some terrible interference on my graphs anytime the TM is engaged. To problem solve I re ran all 10gauge marine wire, installed grounds on all my graphs and Garmin black boxes for UHD and Livescope, placed ferrite insulators on all transducer, network and power cables. I even pulled all wires and placed on the deck and tested with no luck. I have ran just about every concoction with the graphs to try and pinpoint the culprit. For the Ultrex I tested and changed the fuse in the head, added a ground wire to the head, battery output is correct, took fuses out of the onboard chargers to make sure I wasn't getting feed through my cranking or graph batteries. I feel like I have added vibration to the Ultrex that was not there last year along with some "extra play" that I would say is about 1/8-1/4 inch back and forth in the prop. The nut is tight and the washer is in place. The shaft does not appear to be bent. I have spent a lot of extra money in all new wiring, ferrite rings, cable and power protectors etc. I leave in 3 days for stop 2 of the BASS High School open on Guntersville and my front graphs are inoperable when the Ultrex is running. I since connected them to the back transducers so we have something(no issues when connected to rear transducers). I am out of time and solutions other than my gut feeling is telling me something inside that foot pedal or barrel is causing the electrical disruption. Oh, the repair guy at Hartwell said that the screws were to long for the base and that one is broken. He said it appears some did this prior as I have never removed them. Anyone with any advice or thoughts or someone that can get this resolved in a short time frame? Thanks for reading and helping.
You can see in the images when the Ultrex is engaged and how it is when off.
