1993 dt150 ptt problem

[spizard43]

I have a 1993 model 150 that has a nagging problem with the ptt. It will go down any time but will not go up. I hear a relay or something clicking but no upward movement of the motor. Spent $250 last year at local service department who said he could not get the part new and installed an old one. Well, it is doing it again. I wiggled some wires and it started working again for a while and then when I pushed the rocker switch down and then right back up it would raise the engine. can anyone tell me what to check or what is happening and where the ptt is located? Thanks

Sounds like the up relay needs to be replaced, number 10 in this diagram Suzuki Marine Outboard Parts 1998 DT150 RELAY (DT225-225G) Diagram

Thanks-- I talked to a local repair shop and he said that I need to check all 3 rocker switches that controll the ptt. They are supposed to match( whatever that means). He is the one that worked on it a year ago and supposedly replaced a switch which only worked for a while. Does it even sound reasonable that any rocker switch would cause this type of problem? If so how would I check these switches?
