Sony TC-765 Reel To Reel Tape Recorder tape tension issues

I have a Sony TC-765 Reel to reel 4 track 2 channel duel capstan drive 3 motor 3 head reel to reel tape machine. When I got the unit the pinch rollers were gummed up and would not engage. I got them freed up but now I discovered the tape has no tension.

The tape jerks and ends up getting eaten as the left reel or supply reel just freewheels as it's pulled. Doing some research I found that the issue is the left motor is not staying energized or the relay is not staying energized during play.

The motor spins up for a second with no load but then freewheels down. It gets power for like a split second and that's it. Rewind and fast forward work no issues. I checked the fuses and all check out.

The relay is a Omron LC1-C-US-DC24 which is 24 volts DC. it also says 25X7D on it also. The closet replacement I can find is a Omron LC1-C-UA-DC24 with 1512D on it. Are they compatible and am I chasing the right problem or what else should I look for or try?

 

As far as I can remember...... those are the fast wind relays.
They are normally open and close to fast wind. You can confirm that function.

The actual power to the motors comes from the supply/take up motor driver circuits.
These are variable voltage drivers that vary the voltage to the reel motors.

 

I've tapped on the relays with a screw driver and no change. The motor gets power for a split second then freewheels down. Something is not sending power to it. I've included a couple pictures of the drive board. You can see the 2 relays. Rewind and fast Forward work no issues. Right takeup motor works no issues just can't get the left supply motor to run during play.

 

If the relays click in FF or REW...... then they are definitely not the problem.
