While fixing a leak in the mid water tank I came to realize that the Jeanneau branded tank monitor on the boat was reading full even though the tank was empty. During the survey we assumed the monitor was working and the tanks were full (expensive mistake?).
Does anyone know the manufacturer of the 2 tank monitor system used in these boats back in 2004 or should I just disconnect the wiring and start drilling a new hole (ss tank) for an updated tank monitor system?

Although my boat is new I guess it's possible that they were using the same supplier when your boat was built. The tank monitor is a Navigraph model built by Scheiber.
Might be worth checking out on the web.

My 2004 SO35 also has a tank monitor by Scheiber.

Thank you for the postings. I pulled the monitor panel off the wall and as you suggested is was made by Scheiber. I also noticed one of the control boxes for the windass was made by them as well.
Looks like I'll be hunting down minor electrical issues for awhile. The Quick control for the windlass resets when using it with no warning. This appears to be three contributing factors - Weak/Undercharged starting battery, Xantrex inverter/charger not connected to the start battery, noise in the ground line. The ground line noise was the real culprit nd the system works fine whith the engine running once I disconnected the Quick Chain Monitor ground from the BIG black cable on the windless and connected it to a clean instrument ground. Haven't figured out the wiring for the windlass which should prevent operation with the engine stopped. This doesn't have the mod posted on Proboards installed, so now I'm looking for info on the White Scheiber control unit used with the windlass. Metering out the connections I have a pretty good idea how it works, but in my case it seems to be acting as a couple of junction boxes and providing a 10A fuse (only one of the two fuses is wired into the boat)

My manual clearly states that the windlass should be used only with the engine running. But I don't have the battery capacity of a 40DS.

With regard to the windlass, you might have the same battery capacity. The lofrans is connected to the engine battery, not the house bank. A key reason to state only operate the windlass with the engine running is to avoid severely discharging the start battery.
I'll post my observations on the white scheiber control box's functionality after I get my notes off the boat. It appears that it contains unused functionality based upon the SO40 (not DS) wiring diagram and the SHNT between 10-11 may over-ride the alternator input. I haven't found the cross-reference for the warning symbol in the wiring diagram yet.

Fixed the tank monitor tonight. four burned out transistors. These old units with three green and one red LED per tank are incredibly simple. They typically rely upon the resistance in tap water to properly bias the transistors and turn the LEDS on.
Cost of transistors $0.80

Cost of shipping: $2.46
Soldering Iron and knowing how to use it saved $160 for a new panel and shipping from France...
