Bravo One 1997 Carrera 454 Throttle Replace Starter Issue

[thecodymatthew]

Hi all, first time poster and boat owner. (Try to be gentle lol)

So long story short, I've owned my Carrera for about a year now. My buddy replaced the stock throttle lever with a Hardin Marine Billet Stiletto Side Mount Shift / Throttle Control. (https://www.hardin-marine.com/p-744...iletto-side-mount-shift-throttle-control.aspx) It was installed with some struggle and the boat is finally back together.

However, now the engine wont start. With the safety strap in, the engine tries turning over. With the engine strap out there's not attempt to turn over. My questions is, will the engine still try and turn over (starter ignite) with the neutral safety switch not engaged?

Ayuh,..... Welcome Aboard,...... The neutral safety switch kills the "Start" circuit,......
The man overboard switch kills the ignition circuit,......

Interesting. OK so if i start to play with the gear selector when starting, the engine either tries turning over or doesn't at all. So I'm assuming when I'm rocking the selector it's engaging or disengaging the safety, thus allowing the engine to turn over or not at all. So idk why it's not getting a spark now. Does the neutral safety need a ground?

If everything worked before the control was replaced, I would guess your bud mis-wired the control.

The neutral safety switch does not use a ground. It breaks the Start signal to the starter.

That's what I figured. It looked like one circuit on the old throttle, now it's connected to a 4 prong relay with a ground running to the other two prongs. Which hopefully didn't just break the started now that there's a ground connected to the starter signal.

Ayuh,..... Where, exactly is this relay,..??

The new wiring.

I was wrong, looks like there's a ground running to the 4 prong relay (pictured above) but the relay is for the trailer up switch. Purple and Purple White are trailer up. But the ground wire that runs to the other 2 relays is also running to a prong on the neural switch which also has two yellow wires. And I don't see anything on the diagram online about the neutral safety needing a ground. Just a starter connection and and a ignition key connection. The diagram seems very off to me, nothing like I've ever seen before for electrical diagrams.

Ayuh,.... In the diagram, there are No ground wires, at all,......
