Top Gun 500EFI’s Getting No Power
 
Took cover off today after boat had been sitting for a while. Put batteries in…turned on all the switches.

went to turn the key nothing. No clicking no nothing. Trim pumps work, lights work, etc. motors aren’t getting power for some reason.

checked kill switches. Checked neutral switch. Checked all fuses. Nothing.

anything else I should check. Before I start pulling dash and chasing with a meter.

it’s happening on both engines…nothing.

I can check those tomorrow. Given it’s happening on both it has to be something common.

We tried battery selectors on both and on engines 1 & 2.

Does your key start the engine or key on and switch on the dash to start

One other thing to note…not sure of it’s relevance. The shore power inverter seems to be periodically clicking…when the batteries were hooked up

Tested your batteries individually?

yea…I used a jump pack too.

the trim pumps take a lot of power…they sounded strong when I actuated them

Make sure all the breakers in the cabin are on and the red push button breakers by the battery switches don’t need to be reset.

its been a while since i put the blowers on mine, is there still a 50 amp breaker on the engines? its weird that both would pop, also all the breakers in the case where the battery switches are? push them all hard.
