Yam 90 2 stroke

walruz · 21 February 2010, 15:22

Ok guys I need a bit of advice and I'm trying to pull in a favour from someone I know to give me a hand with this problem. My 91 (rebuilt 2006) 90 is giving me some fun. I left her out too long last season and so she got flooded to hell and back. I've just spent 4 hours freeing up the steering and removing it and the engine to run fresh battery leads and install a new 70 ah battery. I briefly managed to get someone who is good with a multi meter and have a strong 12 V getting to the engine, TT working fine but nothing on the ignition although you can here the choke working.

Can someone please give me an idea where to start looking next? My current thought train is to look at the control box next.

Thanks for looking at this and in advance for any advice offered.

I would start by looking at all the obvious thing first. Fuses and relays would be my first choice. I'm guessing here that if you replaced the battery leads, could you have disturbed the started motor lead which might terminate at the same place as the battery leads. Just some thoughts.

Good luck with it all.

You should be getting a bit more than 12v at the engine if the battery is fully charged.At 12v it's not discharged enough for the engine not to turn so I'd be looking for a bad connection somewhere. Either that or your starter solenoid is fubar.

so do you get voltage at the start solenoid when you turn the key?

That's where I need help as I do not have a multi tester and am not (self admitedly) knowledgable enough to answer your question Jizm.

I have someone who is going to help me when he has the time and that is the prob as I ideally want to get the boat back on it's mooring soon ( BUT only when it is reliable).

You could start by buying a simple lamp voltage tester 12v, attaching it across an earth and the positive for the solenoid. A simple visual indication of voltage present.

not brilliant but for less than a fiver you could try one of these.
