Help...Suzuki df250 electrics

Aagghhh...any one out there who may have ideas:

used the boat from a moorings and 5 days later went to run it to beach and i couldn't start the engine.

I have two healthy batteries
I have power to the trim and tilt switch on the side of the engine which tilts the engine up and down as usual.

But i have no power at the throttle for trim and tilt
No power at the key
And no power on all the dials and readouts for the engine.

The actual nav gear on the console is working fine

All the fuses in the engine seem fine as does the main harness fuse....

any thoughts guys cause its bugging me now..??

Is this a wiring loom problem?


cheers
pete

Don't know about the 4 stroke but I had similar problems with my 2 stroke. Turned out to be the crappy bullet connectors which I hate. Try fiddling with the ones on the kill switch/ignition and there are some under the cowl.

Ended up replacing mine with soldered and heat shrink sealed proper connections!!!

Sounds like a corroded connector somewhere in the loom to me.

As Codprawn has hinted, the quality of Suzuki's looms are not their strong point.

I'm afraid you don't really have much option than to start pulling connectors apart until you find the white powdery one.
It should be OK once cleaned up and re-assembled with silicone grease to protect it.

Mine did this once. it turned out to be a 25p [car type] spade fuse which is inline from one of the batteries. It's effectivly a 'master' fuse and if/when it blows, EVERYTHING is off.

Scratch around in the console by the batteries and have a look.

it cost me 2 new heavy duty batteries, various fittings etc before they sorted it.
Ribcraft however where very helpful with the labour charges and also rewired it all on site for me.

It wasn't even a corroded one for me - just loose. They need a bit of squeezing with pliers.

quick thread this one.....YES....found the problem tonight.
My local outboard guy went through the wiring diagram and then tested all sections of loom.
There is a double feed in the loom :one wire coming from the battery via a fuse and joining into a wire that goes through to the computer relay and the other going down the loom to the engine.
Where these three connect was green and powdery....resealed and then over topped with heat shrink and its all lit up like a christmas tree again..

Luckily this join was just under the rubber grommet in the console under the deck so we had just enough slack to pull it out otherwise it would've been a nightmare..

cheers for the help

pete

The memory wire connected to the +battery is prone to failure because it's not protected until it enters the loom. It's a good idea to run a spare lead from the battery + in event of failure. Inside the engine cover on the port side, there's a spare white lead encased in a clear plastic cover. Put 12v to this and it bypasses the faulty lead.

Is this common to all Suzy DF's?
