Our Deere wheel loaders have always had accessory posts which is where we have had VHF radios connected to for decades. This way it only gets power when the machine is running, and we don't have to hear all of the radio chatter if people forget to turn the radio off. It also doesn't drain the battery if we have a machine sitting on the yard and there is a lot of radio chatter while the machine is not in use. Coming from experience, having radio's powered directly from the battery means dead batteries guaranteed.
I have some with fuses and some without. Never blown one yet. The factory wiring that comes with the radios I have does have a fuse, however some radios were installed using previous wiring and it seems to work fine.
I would also like the flasher and the VHF radio on the accessory post as I need to use the accessory socket for a JDLink M Modem power source.
