[GreenKeys] suggestion for ST6 Modification.

I believe the HAL ST-6 does this already.  When the auto-start relay times out, it also disconnects the loop supply.

Subject: [GreenKeys] suggestion for ST6 Modification.
 


Hello all,
 
I’ve been bitten with the autostart bug. As I refamiliarize myself with the ST6 (having not played with it much in a few years).  I realized that even after it turns the motor outlet off, the loop current remains flowing. I thought it would be a good mod to have the loop open up when the motor turns off to safe heat, magnets, etc.  I thought one solution might be to change the motor relay to one that has another pole. Then run the loop through that pole. So when the relay opens, so does the loop.  
 
But I wonder if there would be a more elegant solution that would be purely electronic and not have to change the relay.  Or perhaps there really is not benefit in turning off the loop.
