    Is this the solenoid

    Hi all

    Is this the solenoid that would potentially cause nothing to happen when I turn the key to start. I can jump the red and yellow to crank. Gauges work just nothing when I turn the key.

    anyone know off hand the solenoid I would need on this 454 7.4l?

    I know very little about engines so learning as I go....

    Thanks.

    Yes that’s your slave solenoid. When turning the ignition switch to the start position you should see voltage at the small terminal with the yellow with red strip wire connected to it. The fact that it works when you “jump” red to that yellow with red stripe wire tells me the solenoid is working and the issue is upstream from there.

      I just went through this myself. Check with a meter or test light and make sure you get 12v on the yellow/red wire when you turn the key to start. If you do it’s probably your solenoid.

        John, looks like a previous owner installed a different type of slave solenoid and in a different location along with some questionable wiring connections. I believe you run a Mercruiser in your 91 2556, if so the slave would look quite a bit different and is typically mounted to a bracket forward of the starboard exhaust manifold along with the engine breaker.

          It looks like an older model automotive substitute. The connections are pretty crusty looking. May just need all the connections cleaned up. If not, replace with marine grade OEM unit per Dave's suggestion. And ensure wiring is per OEM schematic.

            Knowing what kind of boat would also be helpful.

            Ok so on the boat now. Yes 91 2556. I thought that solenoid was weird looking and I dont see an engine breaker anywhere

            I did test with a volt meter. I get 12v when off with positive to red and negative to purple. And nothing when in the on position with red to red and black to red/yellow.

                  That’s an automotive distributor with vacuum advance which doesn’t have the proper advance curve for marine applications and is not ignition protected. Being the solenoid is not correct either you should review all electrical to make sure you are ignition protected for safety reasons.

                    Mike is correct. The battery cabling also looks a bit on the small side to me.
                    Is this a new to you boat?
                    Have you had successful runs up on plane with it?

                      Makes sense about the distributer as he put a different one on per this list. I guess I'll put back on a proper one....


                      Here s whats new in it -

                      starter
                      engine coupler to outdrive
                      engine is a used 454 thats hardly been run
                      the carb is brand new

                        New to me yes, and havent had it in the water yet due to life stuff. Just started being able to actually look at it, bought it in July. The guy started it I and ran it for me for a while before I bought it

                          It’ll start with that distributor but as Mike stated, the advance curve will not be correct for a marine engine. Not sure why anyone would remove an OEM TB ignition system. You might find one on eBay or purchase an aftermarket system.
                          This engine came from another boat?

                            I'll start there for sure. But why would I get no current when turning the key to on and nothing when starting? Wouldn't that be something different?
