yamaha 150 will not start or tilt

[bradosh]

hi guys
could someone please advise me on the following.
when i turn the key to try and start my engine there is no response what so ever. not even a tapping noise which would indicate weak battery . also my tilt/trim will not work from the throttle button. or on the side of the engine. kill cord in in place. all instruments and nav lights work ok
my battery is fully charged and all the fuses seem ok

It looks like an electrical problem. Did you tried with another battery?

What is the voltage of your battery after 24hrs?

[bradosh]

the battery is fully charged up . i also tried my new battery off my 4x4
same response off both
last wk all was working ok this is a sudden problem

Put a volt meter on the lead to the trim switch on the incoming side make sure you are getting power, also check to see if power line to the engine is tight and has not been corroded. You could also use the volt meter and start from battery and work your way back to the engine.

thanks sonar

i thought there was only me with a engine problem until i opened up the attatched.
i will carry on reading through the pages but up to now my problem as not been highlighted by others (typical)

there is a slight clicking noise when i press the tilt switch.but no tilt movement on the motor then after a couple of presses all goes quiet.
when i turn the ignition key that is just dead.
i will have to learn how to use a vault meter at the weekend before i pay through the nose getting a spark in fault finding

thanks i will have ago

No worries. You dont really need to understand the volt meter necessarily you just need to see if you are getting power. if you are then you would need to see how much to see if you have an issue with getting the amount of juice required. How long has your boat been layed up? You might have a frozen starter in which case a tap around the starter housing should free it up. just follow the Black wire to the starter and see if you are getting juice their. sounds like the leads to your engine probably from the battery switch are corroded ore lose. make sure all connections are tight. if you have oxidation on them a quick fix to check could be to dump some Coka Cola on them it will eat up the oxidation and allow for additional power to travel. Give that a go.

something to do with the battery leads bolted to your engine, take them both off and tap them together for a split second, if they arc then you won't need the voltage tester, if they don't it's either your leads or battery switch, if they do arc check where they were bolted for corrosion, can't be much else to make trim and starter play up, try turning the flywheel by hand and try putting a screw driver across the 2 big terminals on one of your trim seleniods to see if it works, out of all that i would go for battery switch( if fitted) turn it on and off a few times while doing the trim, tell me how you got on

My vote is for checking the main cbale to the engine - I had a suzi that suffered much the same problem- basically down to corroded terminals o nthe main battery switch - conducted enough to let small amounts of power through to keep the VHF alive, but crank the engine and a load of electrical laws about voltage, current & resistances in series came into play and resulted in most of the voltage showing up across the corroded termainals - i.e the starter got about 2.5V.

It's the high current draw of the starter / trim motor that causaes that to happen. I bet if you have a voltage sensor on one of yout instruments the reading will plummet when you try the trim / starter. - If so, check your cables for corrosion.
