wiring getting very hot

ego.emlyn

lads why does my wiring get really hot when i start shooting just curious

btw i'm using an 8.4 volt batt and a vfc m4

any help would be greatly apricated

It's due to resistance in the circuit.

could it be a number of things causing this or a specific thing? my m4 wires and batt seem to get bit toasty

its just the battery and the fuse get toasty

Its due to high current levels in wiring with poor conductivity, probably because it is cheap thin wiring. You will get heating at points of resistance, if the wiring is getting hot, it is contributing. The draw of the motor, the current of the battery and the resistance of the main spring all would cause extra heating.

You would have to give further details on your particular setup to be more specific, but the first suggestion that springs to mind is replace some of your wiring with a thicker gauge higher quality wire.

Edit: If its just the battery and fuse, maybe replace the fuse with a higher amp one, is the battery a cheap chinese one or what?

BeardySi

A strong spring, poor shim job or bad lubrication will all put more strain on the motor causing it to draw more current.

More current = more more loss due to the wire's resistance = more heat in the wiring. Cheaper light gauge wire will heat up more then quality heavy gauge wire.

I wouldnt put a bigger fuse in , they are there for a reason and thats to protect from electrical faults like shorts or overloads, if you put in a bigger rated fuse then what ever is causing the problem wont blow the fuse in turn it couldend up causing more damage, Could be a number of things, you might have a dodgey battery, loose connection, dodgey motor, gears might be stiff, if the aeg is of good quality, chances are the wires csa (cross sectional area) will be enough to carry the load. Strip it down and go through verything with a fine tooth comb.

I always put 25amp fuses into repairs and upgrades, better than the normal 15A or 20A, as you with decent batteries theres a bigger output.
