    1997 5.7L thunderbolt ignition. Slow crank

    This is my 16th year with the boat And I've never messed with the wiring , So it's been like this ever since I've owned the boat, I just figured I should redo all my battery cables to try to eliminate that as the problem. And that's when I found they just connect to each other. Also when I crank...

    1997 5.7L thunderbolt ignition. Slow crank

    Oh also the ground wire that loops behind the engine, it appears they are joined with some sort of battery terminal in the Middle with a bolt through it or something I can't really tell because the insulation melted to it. I think it's two eyelets ends of each cable being adjoined with a...

    Stumped. No spark.

    It did explain ! I didn't realize that those 2 Gray wires were part of the system, somebody told me those go to the tach and the lanyard safety switch and to just remove them and see if it will start. I put those wires back on and it fires up

    Stumped. No spark.

    OK thanks I'm going to read through this tonight. I put a new distributor cap, rotor and Ignition sensor in , still no spark. I noticed that 50 amp red button doesn't really click like a button like it's stuck. Should that click? If I connect the 2 terminals will that bypass it? Maybe that has...

    Stumped. No spark.

    I got it off thank you. The sensor contact was rusted and corroded, The inside of the button also had rust on it. I tried hitting everything with sandpaper Is to clean the surfaces, thinking I might at least figure out that that is the problem so I can order new parts. But it's still didn't...

    Stumped. No spark.

    So I'm using a test light with voltage. And when I put the test light on it , it does read 11.8 for a second but then it immediately drops down to 10.3 I guess because of the load of the test light. Is that OK? I'm just wondering if the sensor's not getting the proper voltage to it

    Stumped. No spark.

    Removing exhaust elbows.

    Hi guys, I recently removed my engine. To do so, I loosened my exhaust elbows from the 3-inch Riser block ( not from the manifold) to lift up an inch or so so I can get the rubber hoses off. I could not completely remove the elbow because of my engine bay clearance. I removed it enough to give...

    Alpha one Gen 2. Long story short, I had to replace the bushing bc of a broken speedo connector. I wish I had researched first , but it seemed pretty straight forward. I didn't, Yikes. Here's what I did. I turned the L connector straight (forward gear) pulled shaft assembly out, swapped...
