Thread: Help me fix my E-Mag!

    Help me fix my E-Mag!

    I'm trying to fix an old e-mag I have.
    The chip that the solenoid is connected to (upper) burnt up due to a botched solder job on the solenoid from the previous owner.
    I've soldered new lead wires on the solenoid but now I need to replace the chip, the problem is that I cant tell the part # of the chip due to it being melted.(I'm assuming it's some type of SMD transistor or voltage regulator?)
    Anyone know the part number of this SMD item or an equivalent through hole replacement?
    Or even if anyone is willing to post a hi-res image of their own board (rev # ARC3800)

    Thanks for all your help!

    Chip says 451A and has what I believe is a FSC logo. If I had to take a guess, I believe its the NDT451AN.

    Thanks so much for the info!
    I ordered a couple in case I burn one up replacing it.
    Just need a E-mag sear and battery charger and the gun should be up and running again.
