Just how stupid is it to change out a fuel tank sender (diesel) while there is fuel in the tank?

I'll see you guys out there somewhere, Ralph. Absolutely.

Best wishes getting this sorted out now. You sure don't want to get stuck in BFE with electrical issues.

Our old Hunter is on the move again, but painfully slow. We'll be in Rockport tomorrow, after 4 agonizing days at 3-4 knots for 160 miles. A new bottom job, and we'll be on our way again. I hope to catch up with you somewhere along the way.

BTW, be careful if you ever cross the Brazos River when it's running 3 1/2 knots between the flood gates. Crazy stuff, I tell ya. You should have seen Bob's Tartan 41 when he got hit by the current in front of us.

Re: 1989 Hunter 40 - A million questions.

From what I understand the sulfur smell means that the cell is no longer accepting a charge (due to a short, a defect, over-charging, etc.) and is essentially boiling off the acid as the charger keeps pushing charge in - hence the sizzle and popped cap.

I've checked the incoming charge from the Xantrex before and levels seemed right. I'll check everything again when I get this new battery in.

Sure you didn't add Scotch to those batteries?

You drinking cheap scotch again? Definitely not good if it smells like sulfur. Make sure it is above the age of consent.

Don't hit me. What made the starter battery sizzle? Look closely at the whole system before you connect the new bat and have a multimeter at hand. May be just a funkey battery.

Re: 1989 Hunter 40 - A million questions.

Okay - another work weekend on the boat getting ready for our departure in June (we'll sail tomorrow just to get away from the freakin' work!).

I'm working on the solar charging system (write-up coming soon) and bought two more batteries for the house bank today. As I'm measuring things to install the 2 new batts, I hear a sizzle. I trace it to the starting battery and notice that the cap is off of one side. Hmm. Strange.

Not knowing squat about batteries (well just a little bit) - I know that this means the water level is low. So I add some distilled water until full. Problem solved right?

Later this evening I come into the spacious aft cabin with my tumbler of scotch and notice a sulfur smell. Not good. That's when batteries explode and cause fires. That much I know.

So, I douse the Xantrex and pull the starter battery out of the boat. I'll replace it tomorrow.

What's another benjamin?

Hmpf! Sunny Sweden - you are welcome to visit

But if this reasoning didn't work, letī's look on a budget:
Income: if you have 50 W solar panels (which is about a minimum for a 40 ft) then that would give .. mmm... 3 A during 12 hours - in average, if everything is good (I do not get this, but then I am living in chilly Sweden ), summing up to 36 Ah.

Consumption: OK, that is mainly the fridge, and that would be ? A good fridge would average on 1 A on a 24 h duty cycle. => 24 Ah

Then, the other consumeras are the radio, the bilge and some general current leaks. They sum up max 0.1 A on average. => 2-3 Ah.

Thus, you are good!
+36 Ah / 24 hour
-30 Ah / 24 hour

OK, I do not know fridge consumption in your area. It is a question of balance - but it should not consume more than indicated (we can have a separate discussion on that, you bring the beers, I'll have the arguments).

Did I say you need to have at least 300 Ah in total? 400 Ah is better. I known you have been whining about no space for batteries - but this is a question of a) having cold beer and b) being creative. I know you hjave considerable interests in both.

Do you want to hear all the arguments why you should not be connected to AC for a long periods, as in weeks? (Guess some here do not want to hear that, as they are charging 24/7). Separate thread, that too? OK, you start it if you want

Sunny Sweden ...

Smack, I echo everyone else. In the slip,with the fridge off (and with us away from the boat) we leave solar on and shore power off. If the fridge is on then shore power goes on.

I do also have a simple switch in circuit to engage/disengage solar power.

I actually have a lot of switches on a a variety of stuff which I find is handy for diagnosing/fault finding at the least. (When freaky stuff is going on, it is handy to add and remove components one by one).

We have 200w of Solar with a 4 stage PWM charge controller.
