I have an F14 that has a problem. Both lane diverters are not working and all three kickbacks are not working (launch, rescue, ripoff). I am very new to pin repairs. What are some of the first areas I should check?
 
Hey Joe...
First off you should give up on pins and just give them all to me for safe keeping :)
If you can't bring yourself to do that, then ....
- download the schematic (if you don't have the manual [ which would be much better ]).
- Check the fuses (pull one side and ohm them out, do not trust a visual inspection). If the fuses all check out,
- Find the transistors that are controlling the offending devices (i.e Q77 for the upper diverter). Use a jumper wire to short the metal tab on the transistor (the collector) to ground and see if the diverter actuates.
- If nothing happens then either there is no power going to the coil (check from the common lug to ground for 34 (approx, probably higher) Volts DC.) or a connector is bad somewhere.
- It shorting the transistor makes it work, the either the transistor, the drive circuit for it, or (likely) both have been fried.

With multiple things going out like that... look for common components.

Hope this helps a bit...
cheers

Tim, I really should give up on them, I am so much more into vids than pins. Thanks for the advice, I will check it out in the am.
