2003 Yam F 90 - No start

[Kanadakid]

Could use some help /direction.<br /><br />Engine ran fine all day started right up, ideled smooth, ran some at WOT and mostly @ 3/4. Last 500 yards I turned on the Bilge pump. Slowed down so I could look behind to see if any water was coming out. There was none.<br /><br />Engine started to get a little rough, Shut it down. Turned the key nothing. Lights on dash don't light up and Tilt Trim doesn't work.<br /><br />Battery has full juice. There was one fuse near battery, switched that out. <br /><br />Bilge pump, Lowrance and live well work. Just seems engine and ignition dash lights are not getting electricity.<br /><br />Clymers is a joke. I know there are fuses at the engine but can't find them. Clymers doesn't say one word about fuses. How can you ever troubleshoot an engine without knowing where the fuses are.<br /><br />Rod /JB hope you guys are out there still.<br /><br /><br />Thanks,<br /><br />Kid

Take your battery connections off and wire brush them good and clean. Then Use A Pliers to tighten those wingnuts. Finger-tight is not good enough.

Ben,<br /><br />now thats what i'm talkin bout. Can you believe clymers mentions nothing......nothing about those 2 fuses. <br /><br />If one or both of these fuses popped, would thta cause the engine to start running rough ?<br /><br />Thanks, I'll check this out and let you know.<br /><br />Thank you for taking time to write.<br /><br />Don / Kid
