99 Bayliner Capri Starting Problem

[sergiophil]

I have a 3.0 mercruiser and a bayliner capri 1950. Okay, I just received the boat back from a mechanic, which is a long story, but finally got the tight steering resolved. Now, I went to hook up the battery cables and turn the engine over, and I have nothing. When I turn the ignition over, there is no power to the engine. Now this is where it gets weird for me at least. With the key ignition left in the on position, I have power to my bilge pump, but I do not have power to my horn, or blower fan. With the key ignition left on, and when i go to turn the key over, the bilge pump increases in speed, but still no power to turn the engine over. When I turn the bilge pump button off, I lose power to everything. Although, when the boat came out of storage, i connected everything up and turned right over. I checked the fuses under the dash, had a 5 amp fuse out, which i replaced during this and it did not correct anything. So, I started looking at the wiring back by the engine, could my 90 amp fuse on the starter have gone bad or the 50 amp circuit breaker? The 50 amp circuit breaker I cannot press in at all. Any other troubleshooting problems or things to test or how to test them? Is it possible he could have put battery cables on wrong and blown a fuse? Now, I took a jumper wired from the small wired coming into starter to the positive side of battery and the engine turned over, but did not run, just turned over. The main thing is trying to get power to the key to turn the engine over.

Any help would be greatly appreciated. I am going to buy a 50 amp circuit breaker tomorrow since I cannot push it in. Should I also replace the 90 amp breaker on the starter? The starter has been replaced last year.

First, disconnect the battery (negative) and inspect everything. You are probably getting power to the dash through the always-connected feed to the bilge pump. And there's no power getting to the main positive lead. Or from it to the electrical system.
So first thing to do is check the red power leads for clean ends, tight connections, and good wire that's not green with corrosion. Maybe your positive cable is poor.

Figured it out! Was the 55 amp fuse going to the starter, although now my horn, bilge pump and blower motor do not work. Thanks for the help. Much appreciated.
