It looks like there is rust on the body, but it runs and has a plow.  Either the alternator needs replacing or it has a wiring problem.

“For sale is a 1965 Jeep CJ5 with plow. Jeep starts right up and runs good. The generator doesn’t charge the battery but the jeep runs for a while before having to charge up the battery. Plow works good, goes up and down from inside the jeep but side to side you have to do manually. If you have any questions please call Shane at 920-277-1412”
