As previously mentioned check the fuse, BUT
also check the blade fuse holder as over time it can become corroded. Spray electrical cleaner in it anyway.
Battery connected properly? WHITE cable goes from batteries NEGATIVE cable to the FRAME ground and the BLACK POSITIVE cable goes to the inline fuse.
Make sure your battery terminals are clean and tight, also a tight ground connection on the frame.
