    Electrical problem.-gctid370244

    I have a 1988 Capri with a chevy 5.0 and OMC drive. Took it out a few weeks ago and all was fine. Went to start it tonight and nothing. No lights on the dash, bilge, blower, horn...nada. I had power to the switch, so I thought that was bad. Installed a new switch and still no dice. I hot wired the kill switch to make sure that was not the problem. Ayone have any ideas before I spend $100 an hour for a marine mechanic??

      Okay, don't laugh but this sounds familiar.

      My boat also has a 5.0 and on that motor, near the back of it and on top, is a big metal connector with several wires coming out of it. It's help in place with a hose clamp (on my boat anyway) Wiggle that connector around, don't be shy with it. Your electrical power may well return.

      If it does, undo the clamp and pull that baby off. Steel wool the pins as best you can, blow the dust away and lather it with that electrical grease,,,the white stuff,,,electrolyte grease maybe? No, maybe dialectric? Sorry but I forget the exact name but an auto parts store knows what I mean. Anyway, grease the heck outta it and re-connect. You may have solved your issue!

      This was my problem last year and a helpful soul in another boat yelled it over to me last spring when I was stuck about 300 yds off my slip.

      If I am way off base, then I apologize for butting in.

      Good Luck friend, I hope that you solve it

        Ok, I will check my ground and the thingy on top at the back with all the wires coming out. Thanks for the ideas folks!

          On top of the engine is a big round plug that connects all wiring to the engine. They can work there way loose.

            Kill switch? The kill switch wiring can also cause this issue.

              I'm not quite following the above underscored text.

              Are you talking about your main battery switch, or your ignition key switch????

              If your helm power was dead (lights, bilge blower, horn), so would your ignition key switch be dead.

              However, if your helm power was dead, you may still see power at your main battery switch.

              Start with what Craig suggested by pulling the Engine harness/Hull harness interface connector apart.

              All engine data and helm power circuits run up the helm via this harness.

              If the contacts or pins are corroded, this could where the problem is.

              See if there's a red re-set buttom on your engine. Test this by pushing very hard inward on it.

              Also as noted, check all Negatives..... these are often over-looked.

                    Check all of the things suggested in above posts. Being you have an OMC you will not find a red reset on the engine. OMC used a 50 amp inline fuse between the aux. solenoid and haul/engine harness connector. Check and make sure the fuse is good.

                      This applies to Mercruiser applications, NOT OMCIf you have NO POWER at all to the dash, check the 50 amp main fuse at the top / rear of the intake manifold. (#42)There are 2 of these holders / fuses, 1 is the main for everything engine control wise, the other is the main power supply for the trim pump.

                        Thank you all for the replies.I have not had a chance to look at it yet, but will this weekend. I am hoping it will be something easy. And the switch I was referring to was the ignition switch. I showed 12.4 volts at my battery, and 12.3 at the ignition switch. I have one battery on the charger now, and will charge the other tomorrow just to rule that out.

                          There are 2 fuses held in a metal bracket. Should be on the starboard side halfway up the side of the engine.

                          Disconnect the battery first BEFORE taking apart the fuse holders.
                          Be good, be happy, for tomorrow is promised to no man !

                            Well I believe I will have to call in some help on this problem. Its not the batteries or the wire harness. And I thought that I had no accessories working. Turns out the radio and the bilge switch operate, but nothing else. I have a short somewhere and electrical trouble shooting is not my thing.
