    How to use LTspice

    good news! I put a thermistor in my battery and it works, Hooray. Thank you for all you guys helping me figure out the problem. Have a nice day.:)

    Clamp on analog meter

    The circuits seem fairly simple I just need to know what components are in it. Do you have some simple analog multimeter circuits?

    Clamp on analog meter

    I tested my galvanometer and the needle went all the way to the right so I assume it is still working. What should I do next?

    Clamp on analog meter

    HI, I have an old Craftsman clamp on analog multimeter that I want to resurrect. I can't find any data sheet or information about this 82024 Craftsman meter anywhere on the internet. Some components on the board are missing and I want to know what goes there. If anyone has information about...

    How to use LTspice

    I think you can remove the heatshrinked plastic and look inside. Can you do that please?

    How to use LTspice

    Do you know what type of thermistor it is? Which thermistor should I get for my battery? The voltage coming out of the charger temperature pin is 5V.

    How to use LTspice

    I don't, but from your photo I'm not sure where the two black cables are connected to. Could you show me please? This might be the problem!!:)

    How to use LTspice

    I replaced all four rectifying diodes with 1N4007 diodes, but the charger is still not working. The LED indicator got brighter though. What should I do next?

    How to use LTspice

    I resolder every joint on the board but it didn't work, the battery is still not charging. :( I got 570, 580, 700 and 832 on my DMM's diode test function and when reverse bias they all got OL. Is that acceptable?

    How to use LTspice

    I don't have another Battery or charger, but I can charge my battery with my bench power supply. I use 8 VDC to charge the 7.2V battery and have a 10 Ω resistor in series with the battery. It works fine, I can use the drill continuously for about 12 minutes before i need to discharge and...

    How to use LTspice

    My Bosch cordless drill battery charger is broken. When I put the battery in the charger an LED light is suppose to blink indicating that the batt is charging, but the led is not blinking. So I left the batt in the charger for a while but it didn't gain any charge and I can't figure out what...

    How to use LTspice

    There another problem, I can't seem to find the datasheet of 6HKB 07501758 IC any where. Is there a website that will give you this information. I looked at www.st.com but can't find it. This is the picture of the IC.

    How to use LTspice

    I have a problem. I want to analyze this battery charger circuit with LTspice but I can't find the IC in the program. The IC is a 6HKB 07501758 IC. Where can I get the IC? What can I do to make this circuit complete and test it?

    How to use LTspice

    Hi, I'm 17 years old and currently studying electronics at a technical school in Thailand. I want to be able to analyze circuits by using LTspice, but it is really hard to use. I can connect components and draw a circuit but I don't know how to test it. Often there won't be components I need...

    Drill's battery not working.

    I charged the battery for 2 hours with 8V this morning. I measured the voltage of the battery and it was 8V so I tried to use it. The drill spun for 4 minutes then stopped. I measured the voltage and it was 6.2V. Now I want to completely discharge it before charging it again. I want to do...
