Day 10: Slipping Sands

This is a good pick for a foul weather anchorage. It's wet, for sure, but the wind has no sting. We've just been bobbing around the anchor all day while the rain buckets down.

Not much to other than tackle the electrical problems. I have a hand-drawn circuit diagram, that I only partially trust, and I have also started to trace out the wiring. As an emergency facility, a push-button switch pulls in a relay that connects all of the batteries to the starter motors. This is so that you can start the engines on the house batteries if the starter batteries are dead. However, as a side-effect, it also joins all of the batteries to the port alternator. I can use this to fault find the starboard alternator. Turns out there is a problem with this. It can only supply about 12volts and it should be up to 13/14. We need to replace it.

Battery circuit relay.

There also seems to be a problem on the port side and it doesn't seem to be able to fully charge the batteries. Tomorrow, I will try and test the port alternator/voltage regulator. I can also attempt to charge the batteries with the genny which should eliminate more possibles. Slow going, this.

Bulldog clip to tie all boat batteries together - and let them all be charged from the best source.
Small side job was to connect the VHF radio to the plotter. This uses the same interface connections as for the auto pilot. A connection block makes for better maintenance.

This block has the NMEA connections that allow data to be passed between the plotter, VHF & auto-pilot.
