I have an old simpson 160 vom and the battery terminals needed cleaning so I removed the board separated the battery box and found the 22v battery lead broken at one end. anyone know where this wire goes on the board or switch? an old friend who has passed left me this meter and a bunch of other stuff because I used to help him at his tv shop, I would like to get it back in working shape if I could. I think it was the wire broken rather than the battery terminal.

Re: simpson 160 battery lead help
Wow, these analog multimeters are still for sale.
The 260 is quite big but the 160 needs the 22.5V battery.
22V (+) goes to 1.5V (+) and ohms adjust pot.
22V (-) goes to switchComment

Re: simpson 160 battery lead help
How have those of you who have these old meters been dealing with batteries for these units?
I sort of feel lucky with my not-as-good Eico 555 which uses 4xAA's for the Rx10k range...Comment

Re: simpson 160 battery lead help
thanks for the help, got her running perfect now. yep, got 2 260's the 160 which is close to new looking. I didn't plan on using it as I have flukes and triplett dmm's but should the need arise.Comment

Re: simpson 160 battery lead help
Nice that batteries plus still carries that battery. I would have thought they were unobtanium due to the infrequent use of them.
I actually use the Eico more than once in a while, mainly because I can measure voltage or current without having to worry about battery drain down and not need a power cord...
Not much reason to measure resistance on the meter, however.Comment

My question pertains to understanding the control circuity inside a Dell PT434 type battery used in Dell E6400, E6410 and other Dell notebooks?
Does anyone have a circuit diagram for the inside of a Dell PT434 battery and/or a description of how the control lines work to control this battery?
My reason for asking is I have a battery which I cannot get to charge beyond 1% in a Dell E6410 or E6400.
The LED bar graph charge indicator on the battery shows one LED lighted when the info button is pressed.
I have tried multiple different Dell power adapters. My Dell... -
We have an Lenovo Yoga 710 15ISK that we use as a secondary laptop. To cut a long story short, around May 2023, while traveling, I connected the laptop into an electrical outlet that was already switched on. Something made a "pfft" sound and the laptop refused to turn on after that. After getting back home, I gave the the laptop for repair to an informal repair person. He replaced the adapter and an internal motherboard part, but after he returned it I noticed that the LCD did not look normal. Essentially, every alternate horizontal line on the screen had gone missing. The laptop was... -
Hello everyone,
Mark and model: ASUS X571
Symptoms: not turning on. There is only the LED battery indicator working. The owner of the laptop told me this problem arrived one week after having changed the battery. He then managed to power on the laptop only once, and then it never powered on again.
Tests already made:
- Battery is charging when laptop is plugged in. The LED battery indicator turns white after a couple of hours of charge, indicating that battery is fully charged. However, laptop won't turn on anyway, with or without AC plug.
- I have removed... -
I bought a Vostro 3400 motherboard (LA-K033P) to upgrade over my damaged Inspiron 5593 (LA-J091P) board. Everything else is ok except for the battery. This battery I am using now is already a replacement one since I disposed of the bloated original one. Back in the Inspiron 5593 motherboard, the battery charges fine and is identified just fine. However, with the upgraded motherboard, suddenly the replacement battery is labeled as "Not a dell battery". When I borrow a similar battery from my colleague (which did not have replacements yet), it is identified and charges just fine.

The ISL88739 & ISL88739AHRZ are a highly versatile combo battery charger
configurable for operating as either a Hybrid Power Boost (HPB)
charger or a Narrow VDC (NVDC) charger, supporting 2-, 3-, or
4-cell batteries. Both configurations allow the battery to work with
the adapter together to supply the system load when it exceeds
the adapter capability, referred to as system Turbo mode. HPB
charger configuration reverse-boosts battery energy to the system
bus to help the adapter provide the system power in Turbo mode.
NVDC charger configuration...11-05-2024, 03:28 PM
