| Use this guide to return functionality to the 'hand crank' of your SolaDyne LED Lantern Hand Crank. | | | The hand crank is not necessarily the broken part in question this guide is addressing, but it is the crank dynamo behind the hand crank. The [link|https://www.physics.uci.edu/~demos/pdf/el-mag/5k40.80-hand_crank_generator.pdf|crank dynamo|new_window=true] is the part that allows the generation of an electrical current via rotating a loop of wire between two permanent magnets, which then charges the battery which then powers the lantern, in turn producing light. Note where the hand crank in the device diagram is in [link|https://aervoe.com/_files/techdata/7450%20IM.pdf|this document|new_window=true] for clarification. | | | Crank dynamos tend to come with an already attached hand crank, to clear up any confusion about the naming, and not every crank dynamo comes in the same shape and size as the one in this lantern, so do expect the risk of a potential misfitting should you purchase a new crank dynamo. The crank dynamo you will be replacing in this guide is not physically attached to the hand crank, so please purchase one that only comes with plugs, preferably the exact one the lantern has or you will have to do some DIY handiwork in attaching the crank dynamo to the body, as well as to the hand crank, which is not covered in this guide. | | | This guide involves the unplugging of the crank dynamo from the main power board which is connected to the battery to safely replace the crank dynamo in steps 5 to 7, however there are only two 3.6V batteries, so even with an exposed wire there is no risk of electrocution occurring in the worst case scenario of contact with a potentially exposed wire. While it may seem obvious, please do not have the lantern plugged in while doing this guide, and preferably not under the sun either as the top of the lantern has a solar panel installed. |
