SOURCE: CASIO SPF40 battery replacement

"AC" means All Clear. This terminal should be marked somehow. Use a magnifying glass to get a good look at what you are working on. My Casio had an arrow pointing to four copper leads. I used a paper clip to connect the AC terminal (I just picked one of the four) to the + side (usually the "up" side) for a couple seconds and my Casio Sea Pathfinder model 2273 powered right up. See the following link for more guidance.

SOURCE: battery replacement for a G-shock.

The reset trick works with other Casio Alarm Chrono digital watches, such as my old Model W-720, as well. After the new lithium coil cell is installed and secured with the spring clip, the watch may show random segments in the LCD display or may simply be blank. Insert a sewing needle, paper clip, or blade of a small jeweler's screwdriver into the hole on the back of the movement stamped "AC" (All Clear) to momentarily connect the gold plated contact at the bottom of the hole to the stainless steel battery clip. The battery clip in most such Casio watches is connected to the "+" terminal of the coin cell. This will reset the CMOS chip and it should start up with the watch displaying 12:00 and the date at 1-1. Then, use the control buttons to set the time and date in the normal fashion.

Do not lay the tweezers across any contacts as you may damage the watch.
First you need to examine your watch movement and find an AC point (contact). It is embedded on movement. Use an eyeglass, as the writings can be very tiny.
When found, touch an AC point with one arm of tweezers and battery+ with another arm simultaneously.
Some watches needs to do that twice, so, to be sure, do that twice.
If you are not comfortable with tweezers, you can use a thin wire, connecting one end of the wire to AC point and another to battery+.
Each shortcut should last for 3 seconds.

SOURCE: how to get casio sea-pathfinder working after replacing batteries

got a sea pathfinder and just got it back after sending it away to get batteries replaced. Worked fine for a day or two but now none of the buttons work at all - it is still chugging along keeping the correct time but no buttons including the light works - is there a manual reset procedure without taking the back off?
Cheers

Daz

Hi,

it is a tricky way but it can be done...
remove the clockworks completely (that's including the plastic casing) from
its housing
separate the plastic frame from the clock
remove the little screw you spoke about earlier
look at the edges of the big battery clip holder, they latch to the clock
housing at three locations,
pry-off the cover plate...Presto battery can be removed. Before you
reassemble in reverse order make sure that the pushbuttons in the housing
can move freely, lube with light oil if necessay or remove them completely
to remove sweat and dirth

Welcome to FixYa!
You actually do not need to do that. Your watch should be up and running after you change the battery. Short-circuiting the watch is for restoring it to factory settings and it should be done by a watch professional. Doing a wrong short circuit will can damage your watch permanently.
Thank you for using FixYa. Have a great day.

I replaced the battery. was told it needed to be grounded before it would work....yep...how do i that? thx, rick


Remove and reinsert battery.If no result,proceed as follows:
Use a watch tweezer with sharp endings.Remove watch back cover.You will see somewhere on the watch chassis "AC" engraved.There is a hole with contact at the bottom next to "AC".Gently,put one leg of the tweezer touching this contact and the other leg touching the chassis,instantly.Check the display.If no result,try again.This short-circuit/ground will activated the internal circuit and the watch will start working.If you do not have tweezer,you can use 2 watch repairer screw drivers,as well.

You need to CAREFULLY peel back that sticker and on either side of that metal clip is a way to unclip it. I really would not recommend someone changing any of their batteries unless its a "cheapo" watch! If you touch the wrong area with the tweezers you could end up having to send it in for repair! Best bet here is to take it to a reputable watch repair shop and let them do it!

Replace battery for PULSAR Y911. how ro start it?


To restart the watch, you have to short the battery with a pin that sits under a sticker on the back of the watch. The sticker is supposed to explain that. You can usually do it with a pair of sharp scissors or tweezers. Without "jumpstarting" the watch, just installing a new battery won't start the watch. (I don't know why.)

How to get casio sea-pathfinder working after replacing batteries


This certainly put me on the right track,but i found on my pathfinder mod 2271 that the four brass dots located down in the hole were unacessable with standard flat head tweezers so I inserted a small sewing needle and touched one of the brass dots while bridgeing the distance from the needle to the positive (+) surface of one of the four batteries with tweezer legs.
