I have a 1995 Mercruiser 4.3Lx with an Aplha One outdrive. I met a mechanic for a ride along and the boat wouldn?t start. No power to the instruments and no buzzer. He said he jumped the purple to red wire at the starter solenoid and the boat fired up and ran fine. When I got it home it wouldn?t start again. I tried to jump the wires but only heard the fuel pump kick on nothing else. He recommended to change the starter thinking that the solenoid was bad. Put the new starter in and it fired up a few time at the house. Put it in the water and as I was idling out to the channel it died. No power to the instruments and no buzzer.
I have checked the voltage on the batteries, checked the battery switch, replaced or cleaned all the battery terminals, replaced grounding stud and terminals, checked the main harness and wiggled it around as well as the throttle, cleaned and replaced numerous other connections, and replaced all the fuses I?ve found. I replaced the slave solenoid and tried a new ignition switch.
I have power coming to the ignition switch, but when turned to the ignition spot I don?t have any power. However, if I remove the purple wire at the switch and turn the key I do have power going to the ignition post.
Today I jumped the oil pressure switch and nothing happened at first. With the oil pressure switch still jumped I then jumped the red to purple at the starter and the buzzer immediately sounded and with a turn of the key the boat cranked right up. However, with the solenoid jumped the boat won?t shut off at the ignition switch I had to turn off the battery or remove the jumper.
Do I have an issue with the oil pressure switch, possibly the starter solenoid, or a short in the purple ignition wire?
I apologize for the long paragraph, but I?m just trying to cover what I?ve tried. I appreciate your time and input. Thank you in advance!
