That would be our daily user. 580b with a cab. Negative ground. 1975
This one is a 580 CK from looking at some pics on Google.
The wiring is a mess on this thing. Years of shade tree backyard mechanic shortcuts, bypasses and rewiring. Pretty sure the cable ends are the same size but they look to have been replaced. I'll take a better light with me in the morning and look it over better.
There was a 12 volt battery laying under it so I assume it's 12 volt and someone has messed with it in the past and gave up.

Positive or negative ground? How to tell?
