Suzuki DF225 PTT Gremlin

[rcnight]

Gents: My New To Me 2006 DF225 (450 hrs) suddenly developed a PTT problem. All system(s) were working until I lowered it (I believe for the first time) all the way down. Now I get nothing going up, complete silence. Going down works fine, both switches. No motor whine trying to go up from both switches. I have not checked the fluid level, but believe its good since it works as before going down. The one large fuse on the engine is good. Rechecked the harness connections - all good. Can you suggest other areas to check/troubleshoot? Thanks in advance for your help
