Re: Isolated ground solenoid

Before you start chasing zebras, try these simple tests.
Does the engine start id you depress the valeo solenoid and someone tries to start the engine?
If you are able to start the engine then try the following.
Measure the voltage at the engine between the power + wire to the valeo solenoid and the battery ground when someone tries to start the engine.. IF you get 12.5 volts + then there is a problem either with the valeo solenoid or the yanmar black solenoid mounted next to the valeo solenoid.
If you do not get 12.5+ volts then there is a problem with the red wire from the panel. Look at the yanmar B panel wiring diagram.
The red wire is a wire going from the Yanmar engine panel to a 3 wire harness. The wire is Red but it might be spliced into a white wire.
Remove the Yanmar panel and look behind it for a solderless crimp connector joining the 2 wires.
It is about 1 foot from the panel down in the mess of wires. If you have that connection remove it and solder the wires together. That is the wire that both closes the valeo solenoid and starts the engine.
That wire runs to the smallest of the 3 harness connectors at the engine Starboard side possibly under the insulation. There is a red, blue, and white wire on the 3 wire connectors. Open it up and spray it with corrosion x.
I would love to know what you find.
The valeo is just an expensive starter motor solenoid for 12 volt vehicles. . What makes it different is the back actuator button.
If you have an automobile starter solenoid make it is an isolated ground solenoid. If the negative wire is connected to the metal body of the solenoid it is not isolated ground and defeats the Amel bonding.
It could be an internal connection. It is a great spare to have.
The 24 volt valeo solenoid if for the genoa furler mounted most forward port side forward cabin.
The Valeo 12 V solenoid is 160 euros and the Auto version is about $20- Thats a lot of money for a rubber button
Where are you located?
Ps do you have a switch mounted in a white plastic perforated box outboard of the engine stringer and forward of a Calpeda AC pump? It is for a high water alarm. If you have this switch please see if you can identify the maker or at least send me a photo with measurements.
somehow the top 1/2 of that switch disappeared on Kimberlite.
