F%&K!!!!!

So I fish in my boat at least once a week. Today I went to go out and I have no power at the Trim on the throttle lever And she wont turn Over. Changed the battery (it was dead) and Power everywhere else, all fuses on the block good. Trim works on the engine switch. Still wont crank or trim from the switch. Has me stupped. Just fished last saturday all day with no problem. Both batteries are brand new.

Only thing different I did Was add a float switch to the bilge. So i tried cutting the wires to see if if would change and Still nothing. Any ideas?

 

On sunday I added the float switch checked it with the hose both on auto and manual. Worked fine. put the boat up that night and went to go fishing last night (tuesday) and the battery was dead. Whatever it is is draining the battery too. Thats why I thought about cutting the bilge off the circuit to see if that was the case. Still not working, even with new fully charged battery. Im gonna go check it again tonight and see if the the other battery is drained now that I have dissconnected the bilge.

 

Good advice. Did this and the only thing to have power was the stereo. Still no power at the key or throttle lever.

Dont know if this is correct or not but there are no fuses for the instrument panel. Only fuse block on the boat controls the vhf, stereo, GPS and one other componet. There is a main coming off the battery directlty to the engine and the I suppose there is fuses on the engine.

 

This has got me going crazy. Between all the wires on the ignition and the engine there are no fuses. I find this disturbing to say the least. I only could find 2 fuses under the engine cover. Both were good. With all the wiring under the console for the switches, guages, fuel sender, everything there are no fuses. Am I crazy? And to have power to every other component including the lights on the guages is nuts.

From the engine to the battery is a 4 gauge wire, neg & pos, going directly to one another. And the trim works from the switch on the engine when these are connected. But not on the throttle lever.
Im gonna go with sandpaper and put new connectors on the battery and see if that does anything for me.

 

They are separate. The key and kill switch are together and then the trim is coming from the throttle lever beside it. This morning a re did some wiring and brought my test light with me. 2 of the 6 contacts on the ignition have power.

 

I thought about replacing that first but the ignition stopped working at exactly the same time. Even when you turn the key to the on position before the crank there is nothing. The gauges dont flicker the gas gauge doesnt move volts or nothing.

 

Ok so I just went through the whole wire harness under the dash and under the engine cover. Checked all grounds all looks good. Re-crimped some connections on the battery and sanded the contacts. Still no power at the ignition nor the throttle trim. Everything else is working fine. The "ON" position is not working on the key either.

Shouldn't there be a fuse for the ignition?
