[CA] [CA11] Raymarine C80 Radar Issues

[Chuck - Raymarine - Moderator]

Welcome to the Raymarine Forum Chris,

I generally recommend that caution be exercised when considering the purchase of one of MFDs of this generation ... particularly with regard to the availability of cartography, and that parts and service are no longer available many these legacy products (i.e. C/E-Series Classic MFDs, 2D/4D/RD218/RD424 radomes, DSM250/30/300). It accordingly recommended that any second hand product be purchased only after having verified its operation and/or securing a guarantee of operation from the seller.

As indicated within the referenced FAQ, with regard to video, analog, and trigger lead tests no tolerances are specified, the tester will be primarily seeking to determine whether the resistance checks indicate any open circuit readings. Your tests indicate an open circuit within the Trigger test. Failure of the radar cable test may necessitate replacement of the radome connector, radar cable, radome and/or the radar display. The cable may be ruled out by unplugging the radome connector plug from the radome and radar plug from the MFD and then performing continuity tests of the cable's trigger leads. If continuity is verified, then it likely that the radome's circuitry has suffered a failure, as the radar circuitry within MFDs rarely failed. While Raymarine's ability to repair this generation of radomes ended some time ago, you may want to consider contacting SeaWire Marine, Inc. (305.489.1600) to determine whether they can still service your radome.
