dead throttle on 2007 suzuki df250

[mike]

hello,
I had my engine serviced a couple of months ago and upon tucking her up for the winter dropped the engine from the engine trim tab.
I went out yesterday to move the boat and after trying the trim on the helm nothing, I diagnosed flat battery but that appears to be ok as both batteries show 100 %
the instruments do not light up nor does anything happen when you turn the key to start etc.
gps nav echo vhfs all work fine. Is there an in line fuse on the ignition? I couldn't see one tonight by torch light??
the helm throttle is effectively dead, no clicks no lights nothing, the engine trim is fine ie the trim on the engine.
any ideas, fuses or whether it's possible the service has left a wire un connected?
suzy manual useless.
The engine is superb and I am assuming this is a simple matter as the only thing I have done differently is servicing agent, who are very competant and experienced.
needless to say I will call them tomorrow am.
regards
Mike

Hi Mike,
could be a dodgy contact on part of your main wiring. That's where I'd start to fault find. I'm sure someone more knowledgeable will be able to tell more.

Hope it's a short cheap fix.

So, everything that should become live when you turn the key doesn't, but the trim/tilt works?
There's a starting point.

hello,
no from the throttle nothing, all the gps vhf are unrelated so the only trim control is off the engine. sadly absolutely nothing from the helm throttle/ignition.none of it's functuions work and the unit is completely lifeless!
will try fuses today.

Probably the best bet. If it's not fuses and you've got a warranty I'd take it in-the next candidate is the ignition switch.

Sorry to hear of your problems. I had an identical sounding problem with the same (late 2006) engine a couple of months back (although the problem arose in the middle of Christchurch Bay, necessitating a tow into Lymington by the RNLI whose cox worryingly admitted to having the same engine on his own boat!).

It turned out to be caused by corrosion in the 21-pin connecting block which connects the main wiring harness to the engine. If you remove the engine cover, you will see the block towards the top on the starboard side. Not all the pins are necessarily affected and you may have to remove the individual pins to see it.

The problem was solved by replacement of the wiring harness under warranty. Suzuki initially rejected the claim but I hear via the servicing agent (Yellow Penguin in Poole) that Ribcraft (whom they contacted to discuss the matter) had also recently dealt with an identical problem on the same engine.

I can't guarantee that yours is the same problem - but it seems rather coincidental.

Good luck.

turn the key to on, get up the back end and just twist the main loom plug glently backwards and forwards to see if the dash lights up, if it does it's definately what the other post said

[mike]

thanks. I have tried to wiggle it etc but sadly no response, fuses ok, now tracing under dash power cables all thru boat as the hydrocarbon detector which powers up at the same time is also out.
I am going to try again later re wiggle but it looks possible a cable has simply died somewhere and since the electrical circuit seems dead this may be the cause of the problem.
I have removed the batteries and will have a go later at following it to where the igniition joins the loop.

luckily engine is just inside warranty(8 weeks) so hopefully if the loom is dead may have a result, if it's worn wiring (after 80 hours??) will be one of those things, at present I just want it working! the sea was flat yesterday and today until later when it got interesting so a fun day was missed!!!
fingers crossed re power circuit which will be easier and more accessible to sort.

Get it in and sorted. You really don't want them saying the warranty is invalid because you tried to fix it!

[mike]

you are right I think, I have the main agent coming here this am. Thanks for all suggestions I have decided to let the pro's deal with it and then argue about details later.
I don't want to go backwards and cause extra problems so plan B stay in the warm, drink T earn some cash let somebody else worry about it and then have fun in the summer!

Will update with result when I have one.
most odd.Mike
