This makes it more clear to me! :)

oh no,  not the locust.  highdesertranger

Fear the locusts.

They decided to circle my flooded battery today.

I noticed the amps were not tapering as normal, and it got dangerously hot during a regular absorption charge cycle at 118f in the center of the battery.  Senior OHMs is squeezing tighter and tighter within the battery.

Specific gravity reads fair to good though even temperature compensated, and weak cells that previously did not respond to higher voltages have responded now.

Current finances are not ready for replacement.  I wanted to cycle it until a cell failed, but now I am worried it might be dangerous to keep underhood and recharge.

I want a real Deep cycle 12 volt battery.

Trojan T-1275.  175$

My battery tray and hood need modification to fit this battery and it will practically be an interference fit.

Freaking locusts.

I might have to double duty my Northstar AGM, house and engine starting duty. I can plug in overnight so it will only have to deal with house loads when the solar is not sufficient and I am not at my Spot.
 
Tinjiya (Tswana recipe): remove the wings and hindlegs of the locusts, and boil in a little water until soft. Add salt, if desired, and a little fat and fry until brown. Serve with cooked, dried mealies (corn).

Sikonyane (Swazi recipe): prepare embers and roast the whole locust on the embers. Remove head, wings, and legs, in other words, only the breast part is eaten. The South Sotho people use locusts especially as food for travellers. The heads and last joint of the hindlegs are broken off and the rest laid on the coals to roast. The roasted locusts are ground on a grinding stone to a fine powder. This powder can be kept for long periods of time and is taken along on a journey. Dried locusts are also prepared for the winter months. The legs, when dried, are especially relished for their pleasant taste.

Cambodia: take several dozen locust adults, preferably females, slit the abdomen lengthwise and stuff a peanut inside. Then lightly grill the locusts in a wok or hot frying pan, adding a little oil and salt to taste. Be careful not to overcook or burn them.

Barbecue (grilled): prepare the embers or charcoal. Place about one dozen locusts on a skewer, stabbing each through the centre of the abdomen. If you only want to eat the abdomen, then you may want to take off the legs or wings either before or after cooking. Several skewers of locusts may be required for each person. Place the skewers above the hot embers and grill while turning continuously to avoid burning the locusts until they become golden brown.
 
In the US Navy Basic Electricity & Electronics Course (a pre-requisite to the A-School) the instructors explained voltage drop thusly......
Imagine a winding mountain road. The cars are the electrons. The faster they go, the higher the voltage. The tighter the curves the more resistance. Too high voltage for the resistance (the cars going too fast for the curves) they start to fall off the roadside...... "Voltage Drop"! Hehehe........
I also was having trouble understanding the concept of how a transistor worked, particularly the Gate. Then an E6 told me (a lowly E3 student at the time), "Look, Revell, the transistor is just like a sailor, it's basically stupid. It only does what it is told!" BINGO! I understood! :)

I took that navy tron course , not in the navy but in my first year of electronics school.
We didn't hear that analogy but I love it , nice mental image ! :idea:
 
They had other 'visual displays' that I liked. The rope designating the walkway for one area, with a sign on it..... "Warning! Extremely High Resistance!"
And the lab power cords hanging from the overhead, and me asking why they were knotted...... (silly me!).
"That's so the electrons don't leak out!" :)
Yeah, they actually made Basic Electronics fun.
One lab experiment, we were measuring the signal out of the signal generator with an Oscilloscope. I was having trouble getting the output high enough. Finally a buddy brushed against me as I was holding the cable, and the signal increased! Voila! I had discovered inductance! We had a couple more Squids link hands with ours.... I was able to record the proper signal strength after adding the proper number of amplifying 'inductors'!
We also had a constant problem with 'floating grounds'. A problem I could see us van folks having...... Always make sure you have a good solid ground!
