i am trying to get the capacitor off my moped and the wires appear to be soldered (i don't know if i'm spelling that right). my soldering iron was working on the solder i had but wasn't getting hot enough to melt the solder on the bike although it was working a tiny bit. so is there different types of solder and soldering irons? maybe i just need a new soldering iron? my boyfriend had lent it to me and there was also this mini blow torch thing in the case that i was afraid to touch but is that something i am maybe supposed to use? i don't want to damage anything.
