Some time ago the stop solenoid stopped working on my DV10 so I've been using the decompression lever to stop the engine.
Finally bit the bullet and bought a new one and fitted it today.
Got it from the UK for $275 inclusive which is $175 less than I was quoted here in Aus.
So a big saving by shopping around and using overseas suppliers. I would prefer to use local or interstate but that's a big saving for the genuine (Bosch) item inc post.
The old one failed because there was a very slight water drip from the exhaust elbow which dripped directly on to where the body of the solenoid meets the plastic end cap so it must have eventually seeped through to the windings.







So the next job is to fit a cover over the new one to stop it ever happening again...
Was a pretty straightforward job and works better than the old one used to as it seems to shut off quicker.

Nice one, Cockpit. I've made a note of the part no in case I need it in future.

Don't have one in my hand to see water entry points, but one idea could be to consider using liquid electrical tape to seal crevices. It withstands a good deal of heat.

Just have to add that A$500 sure seems like daylight robbery, if you think about what this widget is: a copper wire coil with a plunger in a nice metal housing, essentially 100 year old technology.

Two questions.
Are there still places that do electrical rewinding in Australia?
If so , how much would it cost to rewind a simple solenoid?

When I was working as a port engineer in Singapore , we had everything rewound at a little local workshop.
It was much faster than ordering a replacement electric motor in from where ever.
Some of these were specialized winch or other motors with unique mounting flanges
Two day turn around on a 50 HP motor.

I would have gone Chinese.

I looked at several posts on other forums and no one seemed to have had theirs rewound. A couple of people had taken out the windings and made a mechanical system where they pulled a cable to actuate the plunger.
There was a company in the US who quoted $100 USD but the delivery was the same again so it actually worked out dearer than the one I bought with the exchange rate.

Yep, I had a motorcycle stator re-wound quite a few years ago. I 'think' this was the guy. www.smallcoilrewinds.com.au/index.php/repairs/48-rewinding-service

If he can do stators, generators etc, he should be able to do a solenoid.

I also bought a new stop solenoid from O/S at a similar price for my DV20, but have not fitted it yet. The Bukh manual says they are not a repairable item.

Yeah. You are right Walker.
Looking closely ate Cockpits photos you can see that the cover is pressed on.
Not repairable!
