boatbod ... I stumbled across pr2501's thread and your post re: the SL70 Pathfinder radar
service manual ... any chance I could also get a copy?
My new-to-me Uniflite 42' DCS has this radar. The MFD seems to operate OK (can be switched from Standby mode to Transmit mode by a brief touch of the Power button), however, no imagery is displayed, no error messages appear, and, I can't hear the scanner rotating ... my first thought was to confirm that the main radar cable carries all wires required ... as I have black and green AWG 16 wires that are routed through my tubular SS radar arch
as far as the scanner but have been left unconnected and tied off in a knot
... so that they don't disappear back through the hole they're sticking out of ...
