So i just swapped my trusty old yamaha 90hp 2stroke onto my new to me boat and connected all the cables under the cowling. Then went to hook up battery cables (correctly) and as soon as I touch the last cable to the battery it blows the 20amp fuse under the cowling. I haven't bothered to connect any of the gauges or anything besides the main harness 10 pin connector from the motor to the controls
If the 10 pin is disconnected the fuse dosn't blow is a clue but I'm not sure what it means how how to track down the problem. It ran great last week on the other boat.
Also I tested a bunch of pins in the connector for voltage and 9 of them are hot, at the same time, so that can't be right!!
Got any ideas? Not sure what to try now.
