04 300 hpdi’s !!!!

[Jmyers344]

Need help !! 04 twin 300’s hpdi stall’s when put into gear. I disconnected the Yamaha 60V-8259F-00-00 SWITCH ASSEMBLEY and they run flawless, so I thought maybe the switch went bad. I called my local Yamaha dealer and got two I replaced both this afternoon. Problem is still occurring after new switches installed. If I un plug them motors run fine! Any help would be greatly appreciated. Thanks in advanced

I gather that's the neutral safety switch?
