Looking from some advice from the experts on this great site.<br /><br />I've just purchased a 1988 Yamaha 70 2stroke, which generally starts first or second time.<br /><br />If I switch off the engine after running for 15 mins or so, as soon as I try to restart there is no power to starter or any electrics, yet battery seems to be full of charge.<br /><br />I then have to manual start engine (works first time). Then coming back a few days later, electrical restart is possible.<br /><br />Trim tilt while engine is operating also seems to work intermittantly and several gauges don't work.<br /><br />I'm working through all of the electrics, but any ideas what could be causing such an intermittant fault?<br /><br />Thanks
