    Fixing the Circuit for a DC Motor with Rechargeable battery?

    Just as I am trying to find the faulty components of the main PCB to replace them (by desoldering and soldering), so I will replace (desolder and solder)) any faulty component in the charger if detected. In the previous posts I stated my reasons for thinking that it is highly unlikely that the...

    Fixing the Circuit for a DC Motor with Rechargeable battery?

    Hello poormystic Because of the following reason, it is highly unlikely that the fault is caused by the charger. I have two similar circuits and two similar chargers, as I said in some of the above posts. One of the circuits works well but the other have the faults I described in #1 post. Both...

    Fixing the Circuit for a DC Motor with Rechargeable battery?

    You said "Next time start with that!". My answer is that in the #1 post I mentioned the similar circuit. You said "Post your two circuit schematics Please". My answer is that I do not have the schematic of these two circuits; I only have the PCBs. Will the pictures of the PCB of the second...

    Fixing the Circuit for a DC Motor with Rechargeable battery?

    what I described in the post #1, happens both with new and old batteries, and with two different special chargers for this circuit. I have two similar circuits. In the other circuit that works well, both new and old batteries work well with both chargers.

    Fixing the Circuit for a DC Motor with Rechargeable battery?

    what I described in the post #1, happens both with new and old batteries, and with two different special chargers for this circuit. All of the voltage changes I described in the post #1 happen with fully charged batteries. I have two similar circuits. In the other circuit that works well, both...

    Fixing the Circuit for a DC Motor with Rechargeable battery?

    Hi friends of electronics What you see in the attached pictures is a circuit for a DC motor with a rechargeable 3.6V battery (3 NiMH batteries in series). When the Circuit was OK, its green LEDs lit up one at a time to show that the battery has charged more. But now that the circuit is flawed...
