Cambridge 302 needle stops moving intermittently

[Eric Greenwell[_4_]]

On the last two flights, the needle on my 302 stopped moving. Cycling
the power didn't bring the needle to life, but the everything else
continued to work: audio, slow/fast arrows, averager, MC setting, GPS.

The first flight, it began moving again after a half hour or so; on the
second flight, it didn't start working again until I tried it again
about an hour after I landed.

Is there fix for this besides sending it back to Cambridge?

If you don't want to use the flight recorder, you could open it up and
reseat the inter-board connectors (using contact cleaner sparingly). Strip
and reassembly is not difficult with care.

If you want to use the flight recorder for any claim/competition then
opening kills the electronic seal, so it needs to go to the factory (or
approved repair agent outside the US) anyway after fixing.

some older models had a problem with the indicater coming loose or
falling off,
again requiring an opening of unit to reclue the needle on its axle
and of course a reseal by approved dealer or factory.

Since we talking 302 problems, mine started to loose GPS signal
intermittently. I suspect it is not the the GPS antenna since today
the signal did not came back until I restarted the 302.
Any suggestions?

Hi Ramy,

I recommend verifying that the antenna is firmly attached to the back of the
302 - not just finger tight.

It may be that a new antenna would fix the problem. Or perhaps the GPS
engine needs replacement. I recommend sending it to Cambridge for repair.
