comments to TRACE [RE-wrenches]

[Mark Downing]

Since most of my woes were from toasted DR series
inverters, I started just hanging the LA302DC on the
DC end of the inverter.  Green wire to the inverter's
ground lug, pos and neg to the inverter's DC input
terminals.  I haven't used many LA302Rs, except when
there is a long ac run to another building.
