I have been plagued with the intermittent problems for over 6 months. At 1500 to 2000 ft AGL the alternator quits. Sometimes blows the 5 amp circuit breaker that goes to the field, sometimes it just quits.
On the ground she works fine, even at 2200 RPM with a full load. On again off again with a full load , high speed taxi test. Yet, when I get in the air she quits at about 1500 AGL?
I have a B&C Regulator model LR3C (older and has been repaired) and a B&C alternator plus there has been no technical help at B&C for the last two days (Tim quit and the boss is out of town)
So has anyone had altermator problems and how did you fix it.
I have replaced the battery behind rear baggage in my RV8
Replaced ground cable from the frame to the battery
New bus bar with 1/4 studs from McMaster-Carr
New heavier cable (Stein Air) from bus bar to B lead on alternator
Removed 60 amp circuit breaker from system installed replaced with a firewall mounted DC 60 amp fuse
All cables crimped and soldered at ring end only
Glass panel from OP Technologies has no problem, CrossBow AHRS has no problem. Radios have no problem
Help? any one have any ideas or experience with alternator gremlins
