Now this one has been sitting since 2004. I replaced the battery and had to clean the fuel system. So the tank came off to get cleaned.
This may be where the short is located.
Tank flushed, new fluids, and filter.
I removed a ton of unneeded wiring. Installed a new proper switch. That dash mounted unit has to go!! Turn signals are gone as well. Head light works now and so does the HI/LOW indicator. Short gone!
