Bobby, no I did not fuse the B lead. What amperage would it be if installed? Jeff Jeff, Do you have a fuse in the B lead? Bobby -----Original Message----- From: Jeff Whaley Sent: August-02-18 10:41 AM To: Rotary motors in aircraft Subject: Alternator Damaged - Internal Short Last Thursday I decided to try my cooling on a hot day 32C (90F); orbiting the airport, the cooling wasn't too bad but while waiting for the temps to stabilize I smelled smoke so landed immediately. Saw a bit of smoke exiting the oil cooler plenum so thought I was baking some fiberglass. On the weekend I did a more thorough inspection and found the battery mains cable burned where attached to my alternator cut-out relay and the relay fried to the point that the input terminal was loose. The connections stayed in place but open-circuited the relay - so the engine never skipped a beat and I was unaware there was an electrical problem at the time. Only reporting this now as it took me a while to get the alternator tested. Jeff -- Homepage: http://www.flyrotary.com/ Archive and UnSub: http://mail.lancaironline.net:81/lists/flyrotary/List.html
