I think I just fragged my 150 Yamaha

...of course it makes total sense that Yamaha would place a fuse in front of all else just in case somebody (me) reversed the polarity when connecting the battery! I traced the wires from the up/down switch on the side of my motor and I found the fuse. Went over to Autozone and replaced my fuse, and now my switch is working as normal! Thanks all for your help, much appreciated.switch wiring 1.jpg

The first thing I do when I get new batteries is mark the + and — with a white paint pen.

Glad you got it going

Phew that was a close one I bet that is never going to happen again and one good thing is that you brought attention to that and first thing I’m going to do is mark my terminals.

awesome, glad you were able to figure it out and it was only a cheap fuse.

Great. Easy fix. We all make mistakes.

At least this mistake only cost me $5.00 and I have 4 fuses left for future mistakes! Haha.... Again thanks for the help and support.

No problem. There's a couple guys on here that really know boat stuff.
Not me. I'm mechanical but new to boats. Learn as much as u can from others.
