I have an electrical issue that I need help with. I have a 1996 Mercury 75hp, I just got it after sitting for awhile. I tried to start it for the first time on Tuesday, but for some odd reason I wasn?t getting any power to any part of the motor. I kicked both tires and all of a sudden I got power and the motor started the tilt/trim worked (life was good). So I saw that the insulation on one of the tilt/trim wires were gone showing the bear wire so I wrapped them up. Tilt & trim was working fine, motor was working fine, (life was still good). Then yesterday, I try to raise the motor and the and the tilt/trim would not work, (no power) then I finally got power and the relays would only click. I tried to start the motor (no power), then I finally got power to the starter. (don't know how). Played around with it alittle more, the motor finally turned over and back to clicking. Checked all the batteries, they were up. My meter shows I?m getting power to the motor and tilt/trim, (12.6) This morning I?m still getting 12.6 to the motor. Now the motor turns over, but the bendix on the starter will not return home, it stay engaged with flywheel, but it turns the motor over. I tried the tilt/trim nothing, but I?m still getting 12.6 to the motor and tilt/trim. All I?m getting right now is clicking from the tilt/trim relays. Every time I disconnect the wires from the batteries, (to make sure I'm getting a good connection) I?m getting a spark like I got the wires crossed. (I don?t) I don?t know if this is a short or what, because I?m getting 12.6v?s.
