Video transcript

so in this video we're going to take the the nine volt connector that we have that we're using to take power from our battery and feed it to the bot and we're going to upgrade the wires from around 32 gauge stranded to 18 gauge solid copper wire and so they can handle more current and we know our motors can pull at least an amp each so we want to make sure we have enough current capacity handling capacity with our wires and we'll talk about that in another video so the first thing we need to do is trim off the outer plastic shell around the connector that's I think it's a vinyl shell maybe PVC and we're just going to remove that and expose the the connector and the wires you can see on the back we have two rivets and those rivets are crimped onto the wire and we're just going to pull the wires right out of those crimps and so we'll just have the rivets and the connectors exposed so it's important when you connect these that you make sure to wire them to the correct side so the the the positive one is going to be the one that sort of mushroomed out on the top and the negative one is going to be the smaller of the two connectors there so when you when you flip it over so we're just soldering a little bit more solder to the back of that connector to hold the the positive lead in place and it's important that you get a good flow of solder all the way around and then we're doing the the negative as well and now that we have the two wires connected we're going to protect the back of them by using a piece of shrink wrap so we'll slide the shrink wrap over the wires and then we're going to punch two holes in the shrink wrap for our connections so we'll move moosh the shrink wrap around those connection points the socket points and once we've got that pushed all out around there like that we'll do the other side and then we're just going to trim off the excess with a break off blade knife and then we'll take the get there get the rest of that excess there and then we'll take our heat gun and we'll shrink wrap we'll shrink the shrink wrap so that we have a nice tight connection there that's not going to come apart and we'll just mush the end together while the shrink wrap is still soft okay so now we're going to connect our new connector to our batteries we're just going to put it in and use our large screwdriver to snap it in place once the wires are snapped in place it's really important that you keep them separated otherwise the two two leads on the to the ends of the wires could touch each other and when they touch they'll short out and it'll cause the wires to heat up it could could cause a problem for you it'll definitely drain your batteries so you don't want that to happen so we're gonna feed our black negative wire up through the the hole that we created for our battery wires and the positive wire will also go up through that hole and then it's going to come back down through the hole by the motor and we're going to use once it comes back down through the hole by the motor we're going to connect it to our switch which will allow us to turn the bot on and off and we'll show you how to wire the switch in the next video
