+===== Stanley LED Spotlight =====
+I gave this to him some time ago. The batteries no longer can hold much of a charge so I am trying to replace them, since the spotlight is otherwise in good condition.
+==== Battery Pack ====
+There are 6 AAA Ni-MH 1.2V cells, 700mAh. The outside cover read like this:
+<code>
+Ni-MH AAA 700mAh 7.2V
+Do not dispose of in fire or
+short circuit.
+Lexel 0907.
+</code>
+I couldn't find a direct replacement by searching. 8/16/2016
+There are four conductors attached to the six cells: Black, red, grey and white. I'm assuming there are two wire pairs, connected to each set of three batteries. When I receive replacement cells, I'll take apart the old battery pack and solder to the new cells. 8/16/2016.
+====== Well Pump ======

+Reference: "AIM Manual, pages 13, 46, and 47"
+^Yellow|Common|
+^Black|Main|
+^Red|Start|
+^Green|Ground|
+==== Ground resistance ====
+A good pump needs to have 500K or more between Ground (Green) and each of the 3 wires.
+==== Winding resistance ====
+A good 1.5 HP pump needs to have resistances as follows.
+^Yellow to Black|1.7 to 2.1 ohms|
+^Yellow to Red|7.5 to 9.2 ohms|
+===== Pump not working 12/22/2020 =====
+Rick called me to say that the pump stopped pumping. I went to his house and saw that Julie had pulled the main circuit fuse box in the pump house. There was a heater plugged in, which is tapped to half of the 240 volt supply. I measured the resistance values as follows, and when all looked fine, turned on the main circuit breaker and immediately heard the pump running, and the pressure gauge began to raise. Went inside the house and the water was running fine.
+Not sure what happened. The fuses in the fuse box are cartridge type, and may be old - maybe they need to be replacing, or contacts are intermittent. Also the pump may have a brush-to-commutator contact issue. Concerned that one of the crimp connects could be failing, but the fact that operation has returned with nothing changed (other than disconnecting/reconnecting the power leads to do the resistive test) confuses the cause.
+As of 12/24/2020, the pump continues to run.
+==== Measured Values (on 12/22/2020) ====
+^Ground to Yellow, Black, Red|1.6 Meg ohm typical|
+^Yellow to Black|about 2.2 ohms|
+^Yellow to Red|about 6.3 ohms|
+====== Replaced Pump Again ======
+Rick's pump stopped working, approximately 12/2021. The start winding went to 1.4 ohms, causing the circuit breaker to break on startup. I opened the pump after replacing it, and there was water and a lot of fine black powder inside the motor.
+Purchased a new pump from Home Depot, 1.5 HP. This one is rated at 10 GPM, versus the approximately 20 GPM from the previous one. The original pump that was in place when Rick bought the house was also 10 GPM. This might have made it more durable.

+Eco-Flo 4" Submersible Pump 1-1/2 HP.
+Ben, Robert and I did the installation. It went quite fast, perhaps 2.5 hours. Worked correctly immediately.
+This diagram came with the pump. Although we did not change the wiring, this is approximately the wiring that is in place in Rick's configuration.

+[1/30/2022]
+====== Pump wouldn't run again ======
+The pump wouldn't run. Checked voltage at the pressure switch and noticed that the voltage wasn't going through the switch. Wiggled the contacts with a screw driver, turned on power, and the pump started running.
+Replaced pump with a 40/60 PSI version from Home Depot (for about $27).
+Water restored [7/13/2023]
