Suzuki AP 300 2020 year Lost PTT

[wfw2bar]

Lost my PTT at the end of the year, Relay replaced still nothing. Last year when the boat was pulled out,my trim started working. However, it failed shortly after winterizing. Tim motor is suspected. This week I jumped out the PTT motor and the engined trimmed both directions. No voltage from relay connector to the trim motor. I was able to fish the trim limit switch connector. I have no continuity from the trim limit switch either opened or closed. I will replace next week. The limit switch stops the motor from trimming up too far, would a bad switch stop it from trimming down. I had neither up nor down.

From a 2009 DF90A Service Manual, might be of some use to you…might not

Thanks, hopefully not the ECM

Historically Suzuki’s ECM’s are fairly robust, I doubt that would be the issue.
