Help! It's an older Morse throttle. Single lever it has the cables for the trans and throttle and that I understand I have a white and black wire coming off the throttle and have no clue where they're supposed to get connected
New install? Where were they connected when it worked? Any clue what engine and clutch you have? Any clue what model controller you have? Give us something to work with..
Between the 3 models of I/O cables, additional boxes for many different throttle & clutch configurations, there can be many wires that do not get used. Without knowing any details, the question can not be answered with out poor guessing. I have worked on a few of these rigs, once was a real failure from a lightning strike, the others were induced by the owners trying to fix something that was not broken. For example, there is a wire pair that connects to the dash lights, When enabled, it dims the lights on some of the control heads so they don't blind you at night.
I re-read this post. I had Morse/teleflex electronic controls in my head till now. Now I read mechanical - push/pull cable control. Boy did I have a brain fart. joeb101 is probably correct on the neutral safety switch. These switches can be used on the inboard clutch OR the control head, like for older outboards..
