Century 2000

[Richard Allen]

My century 2000 ap died 2 yrs after extensive repairs from factory. Now they have no technicians and are unable to repair computer.

has anyone had a 2000 successfully repaired at an avionics shop?

also has anyone had an upgrade to another make ap, and how did it turn out?

If anyone can do it, these guys can   @Jake@BevanAviation         https://bevanaviation.com/avionics-repair/

Depends on the failure of the unit.  I am currently waiting on boards from Century to fix a C2000 that is already here.  Century said lead time was 4-6 weeks for board assemblies.  There is a capacitor that likes to short that will cause a pico fuse to open and render the unit INOP.  If you have a better description of the failure that might give me a idea of what the problem could be.

Yes, pitch servo works with external power, 27 volts to engage, and 5 volts to move arm in both directions.

Computer engages servo, but will not turn motor either direction with up down buttons.

sometimes when unit is turned on alt illuminates instead of att.

Roll and trim are fine. 
so in short, when engaged ap will only activate trim to hold alt or att.

Richard if you quote his post or type an @ in front of his name he will get notified that you responded and will be able to respond sooner. @Jake@BevanAviation

If you have tested the motor and it works my guess is something went wrong with the drive transistors on the pitch board assembly.  I would check the pitch servo connector using the up/down buttons and see if you get any DC drive voltage at the servo connector.

I just removed a working C2000 with electric trim, servos and trim switch off of my '90 201.  I hadn't planned listing it on the classified page until next week.  Message me if you're interested.

[Richard Allen]

I’m interested in computer, and possibly pitch sevo if it is working.

does it have a ND 360? Or Flight Director?

when was the last repair on computer and by whom?

Let me know part and serial no’s.

what did you upgrade to?

Richard -

I took my reply offline.  You should have a PM.

Did that. Dc voltage .6 volts at pitch servoconnector.

ps. Also checked voltage at trim servo which works fine. 10.0 volts

@Richard Allen .6 DC drive voltage at the servo connector is way low.  My guess is something failed on the pitch board possibly drive transistors.
