Gun not working after upgrade

[Pancake]

I upgraded my guns internals, and now it won't fire. My motor click everytime I try to fire, and I think I heard a click in my gearbox once. After trying to fire a couple times my battery got warm and my wires were hot. Whats wrong?

Which parts did you upgrade? And what type of gun/gearbox is it? Stop trying to fire your gun if the motor won't rotate, you will blow a fuse and break other stuff that way. My guess is your anti-reversal latch or something else is jamming the gears.

M120 spring, High Torque Motor, New cylinder and piston set. 9.6v battery.

Yeah you are gonna have to open up your gearbox again and look at it, maybe post some pics. Or take it to a tech.

I just checked my gears and they spin fine, so everything should be fine.

Obviously they weren't when your gearbox was put together. Make sure your anti-reversal latch is on the correct side of the bevel gear and the gears still rotate properly when you have it in place.

no i tried spinning them when it was put together, i think i found the problem though, i think its called my tappet plate, whatever is connected to the air nozzle. I think that its not being pushed back like its supposed to, because everything else looks fine.

Try pushing the air nozzle back and see if that pops the tappet plate into place. Or you might have to open it up and adjust it. OR, your motor adjustment could just be off. If you can spin the gears but the motor can't, that might be it.

When my gearbox was assembled I could push the air nozzle back just fine, ill try reassembling it. Okay my air nozzle doesn't have any resistance, so i don't think the air nozzle is on it right.

The air nozzle should fit into the cut out part of the tappet plate pretty easily.

The nozzle/tappet plate wouldn't cause that. If the wires are heating up, check all the soldering points and check for pinched wires and try a spare motor in your gun. When you check to see if the gears spin freely, make sure you close the gearbox AND screw ALL of the screws in it when you test it.

The simplest solution would be flipping the motor contacts, see if that works

This. (make sure red is to red and black is to black).

If that is what is happening your motor is attempting to spin backwards but is being held back by the anti-reversal latch (just doing its job) and results in heating up the motor and wiring (along with blowing fuses).

Im with pseudo, check your rotation direction.
If that doesnt do it, then check your shimming - as in, take your gearbox down, take the cylinder, spring, and piston out and screw your gearbox back together - see if the gears spin freely.
If thats the case, then I really dont know what else to tell you.

I predict it'll be miswired contacts however, and the motor is spinning backwards.

this +1.

also, not all motors have black as the negative contact. for whatever chinaman reason, a bunch of the aimtop ones are reversed.
