300 hpdi. No Power to engine or trim/tilt

[reel_adventure]

When trying to start engine this past week, could not get any response from engine when turning key. Thought the batteries were dead and had them charged. Replaced them but still no response. Put throttle fully forward then in reverse then back to neutral and engine started.

Was cruising later in the day and engine cut out and similar no power situation. This time nothing seemed to work. Came back using my *****ing motor.

Checked the fuses but all are OK. Did notice that after turning the battery switch off them back on I hear a click at the engine when testing the trim\tilt but nothing else. Also when I installed the charged batteries and fired up the engine the first time, I heard a snap sound but only when starting the engine the first time.

Any ideas on what to check?

battery connections? and main power cables to engine,

Thanks for the suggestion. Battery cables are fine. Tried to jump the starter with fresh 12volt source and no action. Seems that the starter solenoid tries to engage but stops.

Arranged for a service visit from a Yamaha dealer so maybe he will be able to diagnose the problem.

Actually it was the battery cable - the main cable from the power switch to the engine. It was badly corroded. Had it replaced and engine worked fine.
