I've been having issues with getting power to my John Deere 260. I replaced the ignition switch and the PTO switch, and while I was able to get the power, and get it running it still seems like I'm having connection issues. I fired it up last night, turned the lights on the PTO on, and the aux light turned it back off to get one of the lights working again went to fire it up, and no power. I jiggled the connector on the PTO then did the same to the ignition switch then got my power back, I'm hoping this isn't the new norm. The terminals in the plug don't look too bad, but what is a good way to get them cleaned up that isn't too intrusive and doesn't involve soaking them, I don't have a garage.
