No power anywhere, even with jumper cables
 

My buddy has a 99 Baja, been on a lift for a week, normally no problem. Goes to start it, nothing. Ignition on gets power to 1 gauge, I think the trim gauge. When key is turned to try to start the boat, the gauge needle will flicker, orthwise nothing, no warning beep or fuel pump either, even horn won't work. Hook up jumper cables to posts next to battery switch, still a no go...wierd. I would think if there was any power at all the horn would at least work, but no...ideas? Worst of all with no power can't open hatch. Help greatly appreciated!

most hatches can be pulled off of the lift ram when this happens. give that a try. then the grounds and big red circuit breaker that kills the whole boat. worst case, you hafta find wiring under dash for hatch lifter and jump right to there...

I'll give that a go. Should mention the main fuse blew without time to replace it (starter fuse) so we wired terminals directly to starter.

You can get the hatch open by running a 12 volt power wire from a jump box or good battery to the back of the switch.
