[Milsurplus] Wire size

[CL in NC]

If you are running an ART13 with its DY17 dynamotor, what size wire are you using between your 28 volt supply and the input to the DY17?  My power source, a 125amp switching supply with a pair of auto batteries across it, voltage sags at initial keyup and causes the ART13 to double click the antenna relay before staying in TX.  It is only a fraction of a second, but enough to worry me. I thought what I am using would be big enough based on how it filled the solder cups in power plug.  The dynamotor is a Ballantine manf. unit with little to no run time as brush and commutator wear seem to show.
