Ed, Make sure that you put the RV7 switch in the correct position(s).  If you did, then proceed. If you didn't even have lights, I would check the bulb.  Take it out and make sure it lights on 12 volts from a small power supply.  If the bulb lights, then I would look at the jones socket on the

The TR-7 nylon gears are not affected by oil because the gear bushings are brass on brass. The older PTO's used a nylon gear over a brass bushing and oil is a problem. I have had to disassemble many older 4 line PTO's with binding gears and open up the hole in the nylon gear with a wood dowel
