John Deere 318 Front PTO problem. I need more help!

Hello, I need more help with my John Deere 318. Now I have a problem with my front PTO, it is the one that runs the mower deck. Normally when you flip the switch you can hear an audible sound when the PTO engages and disengages. Now when you flip the switch, you can see the dash lights dim, but no noise. I took the field coil out like the manual says and a bolt sticks to the electro magnet when energized and falls off when it should, so I believe it is good. Side notes; The indicator light for the front PTO does not come on any more and I am only getting around 9.5 volts down to the PTO from the power source. Another thing to mention is after the compression problem was repaired, and the engine was put back together we tried to start the tractor, when the we turned the key to the start position nothing happened until we flip the front pto switch, then it started turning over. After awhile it started turning over like normal. Any thoughts or suggestions would be helpful. Thanks, Jack

Jack u have a wiring issue under the battery.Mine was acting in a similar way once before.For my problem it was the single wire that hooks to the ign. switch.I do believe it had an inline fuse.I used an inline fuse holder, blade type 30a fuse from NAPA.That fix my troubles.I do remember the light in the dash was acting funny.
 
Here's a wiring diagram for the 318 with 2 pto's. Hal
