Questions F43

[KajLehtinen]

Hi!

More questions on my F43 and its installations.

1. Those of you that has air heater (webasto/ebersprächer), where has Sealine mounted the fuelpickup? My installation that was done when I purchased the boat had the fuel taken from the main fuel line from the port side engine, which worked fine in the beginning but after 2-3 months of use it stopped working and gave error that it had problem with getting fuel.

2. The attached picture, what does the the battery isolation switch do exactly? Kill everything or separate start / aux?

3. The thing under the white box is, I guess, the relay that joins aux & starter battery banks if one needs that (Crossfeed). But what does the white box usually consist of? I havent opened it yet, but will soon do that I guess.

4. The black thing, is that a charging diod relay for charging the bowthruster bank?

1. Separate pick up near the rear of the Stbd tank. Pump is on the engine hatch cross member.

2. Can't remember but I think it kills everything.

3. White box consists of a nut and botl connecting all of the negative wires (I just had to look in mine)

4. Can't be sure but I think it may be the charge for the main and aux batteries, not sure where the bow thruster battery gets it's charge. Did put a question on here re split diodes but never got the answer.

Have you checked the filter in the fuel pump for the heater,could be blocked.

Small black box is relay for split charge from starboard engine, they do fail quite regularly when you use the jump relay if the stb engine is running as it overloads it and burns it out. Better replaced with volvox propr split diode pack in my view. It has no moving parts to burn out. From pic I see jump relay under White plastic box.
