Quoted from rwarren28806:
Manual calls for FL23/600-30/2600 for all 3. Replacement from Marco website is SFL-23-600/30-2600. Not sure the significance of the dashes vs slashes. Probably none.
That's probably more my data entry than anything else.
But that leads to a follow-up question. I have a SFL-23-600/30-2600 coil. But that coil has the one diode on it, while the drawings in the manual have 2. Is that significant? The wire hookups look to be the same based on a prior pinside post about parallel and serial coils.
