RonH Posted November 11 Report Share Posted November 11 Cheers, I recently purchased a USB port from Leonelli so I can charge my phone so I’ll have GPS tracking. I live in the Pacific Northwest and it’s very easy to get lost in the forests around here. I’ve tried connecting it twice without and luck but I failed both times. I have their instruction but I can understand what I’m supposed to be doing. I’ve contacted several people for help but nothing has worked. Below is the schematic and if you understand how it’s suppose to be attached please get in touch. My bike is a 2023 Gasgas TXT and obviously has no battery. It just gets its power when the bike is running and generating charge. im no electrician by any means and the diagram is confusing to me. There’s three wire coming from the unit. One goes to the USB which is a no brainer. The second is a ground wire which also is easy to figure out but the third is where the powered device is supposed to be attached. It shows two methods of attaching it but it’s confusing. There are two snap on connections to the power wires and I have no idea where they’re supposed to attach. Thanks guys and gals!

RonH Posted November 11 Author Report Share Posted November 11 I forgot to add my bikes wiring diagram if it helps at all. Quote Link to comment Share on other sites More sharing options...

RonH Posted November 11 Author Report Share Posted November 11 Thank you. I’ll give it a try. Quote Link to comment Share on other sites More sharing options...
RonH Posted November 11 Author Report Share Posted November 11 Thanks for the suggestion Lemur but the Vista port "L" Salida 12VDC output doesn’t seem to exist on my bike. I can’t find it anywhere in the jumble of wires. I’ve found the regulator/rectifier and the CDI. The rest is wires and connectors. I’m sorry if I’m being an idiot but between an Italian diagram, a Spanish diagram and my parts diagram nothing looks the same. They all use different symbols and I’d hate to have to spend another hundred or two hundred dollars to have someone attach a $45 part.

lemur Posted November 12 Report Share Posted November 12 Follow the fan wire all the way back to where it first joins in with other hot wires, that is a reasonable place to pickup the positive connection, use the chassis ground for the negative. The fan switches on and off by make or break of the ground connection via the thermostat switch. Would be cheaper and easier to buy a USB battery extender. 1 Quote Link to comment Share on other sites More sharing options...
RonH Posted November 12 Author Report Share Posted November 12 I just have to say that I’m really impressed by your knowledge and willingness to help others. You’ve certainly been around the block and speaking for others we appreciate your efforts. I’m new to this and have a goal of doing all the maintenance and work on my bike myself as is reasonable and it’s others like you that make that possible. Thank you Lemur! 1 Quote Link to comment Share on other sites More sharing options...
lemur Posted November 13 Report Share Posted November 13 Love electronics. You know those computers (objective auto-refractor) that automatically tell you what prescription you need for glasses or the (NCT) machine that puffs air into your eye to read your intraocular pressure, I use to on-site repair those for a living, motorcycle electrics are bone simple. 1 Quote Link to comment Share on other sites More sharing options...
RonH Posted November 13 Author Report Share Posted November 13 Lemur, Do you think connecting the hot wire on the USB tomorrow the out/positive wire from the Regulator/Rectifier would work? I have an electro tap to make connection. The wire happens to be black where id like to make the connection. I’d assume it to be red but what do I know. 1 Quote Link to comment Share on other sites More sharing options...
lemur Posted November 13 Report Share Posted November 13 (edited) Simple test meter is very inexpensive and even a cheap one works, they are just easy to break compared to a expensive one. The device you bought is just a 12 volt to 5 volt step down transformer and some diodes to make it so the device can even run on AC. It will run off anything that is hot when the motor is running because you have no battery, it doesn't even need to be on a switched circuit. and yes I think you found a reasonable place to connect it as it draws very little power. Edited November 13 by lemur fixed it Quote Link to comment Share on other sites More sharing options...
lemur Posted November 13 Report Share Posted November 13 Hard to see on the documentation but I think it says it will operate off 6-30 volts ac/dc and that it is a voltage regulator. That implies you could run it even if your bike has no regulator/rectifier hence the optional connection method choices. ... likely not a step-down transformer as such inside the little black box, most likely contains all semi-conductors. It will work until you exceed that 30 volts. Quote Link to comment Share on other sites More sharing options...
