I got the Comanche back together and flying on Monday with the help of my A&P. I ended up replacing the main feed wire from the alternator to the breaker panel. We also replaced the 60 amp alternator circuit breaker and three other breakers. I could find no wiring issues with the landing lights other than slightly corroded connectors at the lights. However, due the overall weakness of the system I decided to replace both landing lights with LED lights. They are awesome and well worth the money. They only draw 6.6 amps when both on compared to 16 amps with the old halogens.
I flew it with everything turned on, gear moving, flaps moving and no issues.
One thing that surprised me was that piper ran 4 gauge wire from the alternator to the breaker. Then on the other end of the breaker the power is distributed via 1/16" aluminum bus bar. Just doesn't seem right but I guess it works!
Thanks for all the input!
