Re: SM 2000, Yanmar, negative solenoids isolating the engine

Naegels Patrick <naegels@...>

Hi John,

This solenoid is not displayed in Yanmar documentation, because this
is an Amel add on.

Indeed, you can meet some difficulties to turn on or off your engine
with a solenoid in bad state.

I replaced mine after 5 years. You have to buy one from Amel, it's
the same item as Windlass one, but in 12v instead of 24V.

It's not very easy to replace because this spare part is rather
inside engine. We did it at sea, very uncomfortable ...

Good luck

different source. A meter reading on the feed to the solenoid from
the stop button reads about 6 volts until I short out the terminals

stop solenoid works.
Ant help would be much appreciated as otherwise I have to queue up
