I had the boat out last weekend and it has been running great, this week I installed a fuel gauge and today I got it out to get it ready for this weekend so I went to start it and I got nothing. it doesnt respond to the tilt trim button on the throtle and when I turn the key I get nothing, I do see the voltage gauge move when I turn the key but nothing else. Not sure where to start. Thanks for any help your able to give.
