Went to the local aquarium this afternoon for a sort of time off. They had a new exhibit--"Odd Water". Showing the odd fish in the sea. Lots of them. Really a very nice exhibit. Lots of kids as well as adults. Apparently, it is one of the best aquariums on the entire West coast. Who knew--and it's right down the street behind the marina.
Now that the forward head tank has been refiberglassed, I went about filling it with water to see how much it actually held and since it had been cleaned at the last pump out, I could freely empty what I poured into it with a clear conscience. I got to 6 five gallon portable tanks and it appeared to be full so it holds a lot more than we thought. Plus the existing pump got rid of all of it. We did buy a new pump that will do a better job getting rid of what is in the tank. I'll be installing it in a day or two.
There is nice weather coming--at least that is what the weather people are saying. We could finally hit 60 tomorrow!!! A heat wave-finally!!
We still have to start installing our new wind power generator. With luck, and good weather we will start on it tomorrow. There is a forecast for high winds off shore so we will see what we get here in the harbor. I'll take a nice breeze but not the gail force winds they are talking about.

The shunt is used by the battery charger to measure the current going through the battery bank. It turns out that, in electronics, it's easy to measure a voltage but it's tricky to measure current. A shunt is something that's used which converts a lot of current into a small amount of voltage which can be measured.
Physically, a shunt is typically a block of metal which is precisely shaped to have a very specific (but small) amount of electrical resistance. I'm pretty sure I remember seeing the shunt for your battery charger installed, so it's likely you already have one. However, in order to properly calculate the amount of current going through the shunt, the charger has to know what the resistance value of the shunt is (shunts come in a variety of values). For this reason, battery charger systems either provide you with their own shunt or explicitly tell you what shunt you need to provide it. It's not certain that the shunt you had installed on the old charger will work with the new one. If you find your old shunt, you might be able to read what its resistance value is ). The charger manal will specify what value of shunt it assumes.
Also, the charger will have two 'sense' wires that need to connect to either side of the shunt so it can measure the current going through it.
