I had a similar problem no power and found from this forum someone hooked by battery cables up wrong. It didn't blow any fuses, relays or charging system. I hooked the cables up correctly and all works fine now.
You are absolutely correct the battery was hooked up wrong. There are four large battery cables and two of them were switched. I have the boat winterized by someone else and I remove the battery and drop it off to them in the spring. I used the boat one time and it worked fine but the second...
I started using a meter. I could be wrong but to me the boat is USA made with positive being fused and mated with a Japanese motor which fuses and switches the negative side. Do you take it that way.
Okay I've checked the power at the bl/w wire which is a negative 12.76 volts. This is what I think is funny that this boat will key switch the negative but in the helm all the fuses are positive and the fuse on the motor are negative.
I need to mention how this came about. Boat sat for a few weeks and when I went to use it I trimmed the motor down and it sounded like a lot of arcing and it went down slow before everything quit.
The wires are isolated now but the bl/w wire is not easy to contact. The bl/w wire goes to the green plug but I haven't been able to disconnect it yet.
Very confusing everything is switch on the negative side making things much harder to understand. Honda BF50D. All the fuses check good there is no battery switch and the kill switch has a negative to both sides of the wires without it being hooked up. I've been using a test light and should be...
I don't have power anywhere to the dash or trim. I check the fuse box with all fuses testing good. This is with the battery load tested good and positive breaker jumped. Any thoughts would be appreciated.
