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
