(02 Yamaha 200 hpdi )This could be completely unrelated but ..So at the end of last season I was having an issue with my motor not passing water through the pisser tube . Cleaned it out everything works there now . The rectifier was jammed up with some dry salt. Ever since then when I use the power trim switch on the controls when the motor is running it nearly kills the motor or stalls.it works fine when motor is not running . I checked for any pinched wires around the rectifier and fuse box, nothing. If I use the switch on the side of the motor I have no issues at all even while running. I tried checking the block to see if it was shorting and came up with nothing. Any suggestions are greatly appreciated before I look into this soon with boating season coming up.

Sounds like the T&T is pulling the voltage down.
clean all battery cable connections and make sure your battery is load tested and good

If I use the trim switch on the side of the motor it’s perfectly fine , only when I use the one on the controls .
