all i could see on my unit without taking it apart was a burn mark on the inside of the unit around the indicator lamp. it looked to me as if one of the wires attached to the light had made contact with the side of the hole that the light emerges from. once again, as i did not want to void the warranty i chose not to open up the vape and take a look at it even though i did have the urge to see the inner electronics of this vape.
i surmise that the electronics are very basic with a 3 way switch one side would go to a small trimpot to control the temp the other side of the switch would bypass the trimpot and provide full line power to the heating element. also in parallel with the heating element would be the indicator lamp being very close to the inner workings of the silver surfer vape. which the power would go to a pot then to the heating element with a lamp in parallel. the major differance being the addition of the 3 way switch to provide full power on demand while retaining the settings of the trimpot, and the ssv also has a 3 wire grounded plug grounding the whole vape (as it is all metal). so the 3rd round prong of the plug would be attatched to the inside of the ssv to the metal surface so in the event that any malfunction of the electronics, the user would be protected.
thats why im pushing very strongly for epicvape to add a 3 wire plug to their vapes, to protect the end user. even though this seems to be an isolated event, if it happened once, it could happen again. The 3rd wire would be screwed into the metal base and would protect against shock to the user. even if the user were to drop their vape into a full bathtub the grounding plug "should" protect the user. With exposed metal parts that can potentially make contact with 120V 15 A circuit there should be some sort of grounding in place. as it only takes .06 amps across your heart to kill you, 15 amps is enough to kill you many times over. people get into the habit of thinking that the outlets in their house are safe because they are "only 120 volts" and are located in their living space, when the truth is many people a year get killed by imporper grounding. weather by removing the ground plug to fit into an older style 2 prong outlet, or by having an outlet that is not properly wired and grounded.
