From: Chris Zach via Elec-trak <elec-trak cosmos phy tufts edu> Date: Wed, 1 Sep 2021 14:37:41 -0400 Only annoying thing about the E15 is how it fries relays when going from F to Reverse. Unless you are totally stopped the field coil will burn up the relay. Isn't there supposed to be a varistor or something to protect the relay from this damage? Ken
