    So... I got my new Systema Motor Long Power Torque Magnum.
    Pretty excited... so I pulled out the JGM4A1 and started the removal/install
    process...
    1st... I accidentally severed the red wire... Urgh.. fixed it. no problems.
    2nd... I install the new motor and got off a good 30 rounds, not enough to test any improvements, and BAM! the gun stops working. No power into the motor....
    I blew the darn fuse.
    What to do? I guess get a new one from the hardware store. Hopefully they got it.
    I wonder if this will just happen again, or do I need to upgrade in fuse or what?
    any suggestions?

    Im no electronics wiz, as you might have guessed!!!

    hi,

    although i wouldn't recommend it and you will have decide for yourself also i will no accept reponsibility for it, you could removed the fuse altogether. Me and my teammate just removed the fuse because we change the battery from standard 8.4V to 9.6V, even try 12V. I think there was a review somewhere, i forgot where, that say fuse removal is not really an issue. I have been playing since 2006 without the protection and did not have any problem. But once again, do it at your own risk. Can anybody else comment on this ?

    thanks.

    best regards,
    arctur

    I remove all the fuses on my guns.

    Since you have an M4 it will have version 2 mech box which means u ran the wires inside there are a lot of people who have issues with the gears stripping the wires if not placed correctly.

    Another possible problem was you over tightened motor plate and it was not seated correctly and after a few shots pretty much locked up and blew ur fuse.

    If you are comfortable I would take the mechbox apart clean it spray it down with tri-flow (teflon coating) reshim it and make sure all the wires gears etc are in working order.

    Ok guys! thanks for the all the replies and suggestions.
    I have confirmed, based on the shooting with no fuse thing, that it is indeed the fuse.
    the fillament is in 2 pieces and it works with the fuse connectors connecting to eachother, minus fuse ofcourse.
    So, this is just a temporary fix.
    what are the potential hazzards of running with out a fuse.
    btw, I am using an 8.4volt battery.
    I think it runs a bit hotter now....

    Many people run AEG's without a fuse, the fuse is there to protect the AEG from a power surge or jolt.

    Many things can create a short within the electrical so the fuse is there to act as a bouncer to prevent the surge before it hits the juicy innards.

    People I know have had little problems without the fuse installed, however one local I know had to replace all of the wires and replace his mosfet board as a result of surge from his new lipo!

    The fact is gentleman the fuse is your first and only defence against power surges, many disregard this however know that without a fuse your internal electricals are always at risk.

    So my advice is go buy a 20 pack "o" fuses and save the worry..

    :D

    Hey guys, thanks for all the replies. I will get a good supply of fuses, as suggested.
    Better then having to repair the internals if they get fried...
    thanks!

    You can always install a mosfet to replace the fuse... it acts like what a speed controller would do on a RC car.
