Alternator type terminal
Hi,
I 'm an italian student(then excuse for my english)and i've a problem with my alternator(120 ampere installed on a Lycoming 360);my problem is the broken of the wire on the terminal of my alternator,the terminal is intact but the wire result as cut. The reason for me is the high vibraction in the zone of connection of the terminal on the alternator and I don't know if the broken owe by the rigidity of the wire(the size is for the positive 4 AWG and negative 6 AWG,the type of the wire is Raychem for aereonautical application)or by the wrong crimp. I wont ask at you that type of the terminal is indicated use in this case?(I utilize a Amp PIDG terminal form square);exist other possibily cause? Thank you in advance |

Thank you in advance I am positive that your English is better than my Italian. The main reason for the wire breaking would either be the wire routing, or possibly a bad crimp. The wire should be routed with some slack, and should be mounted so it can flex/bend somewhere away from the terminal end when the engine is running. The wrong crimping tool can also cause problems. The proper wire and stud/bolt hole size AMP terminal should work fine. Regards; TC |

First I would try to get rid of the vibration. Find someone with a
helicopter balancer. You might try replacing the stiff wire with flexible silicone jacket welding cable of the same size since this will take much more flex before it breaks. A small loop at the terminal will tend to distribute the flex over a larger length and help stop the breaking where the flex is concentrated. Crimp terminals are better than solder in high vibration enviroments.

Hi,
thanks very much for your information,i've appreciate your interest,but i need of another information: You talk to sobstitutewire with flexible silicone jacket welding cable but i don't know this type of wire,be able you to give me factory link or other information for this wire? Is this wire usable on the aircraft of general aviation?(spec. militar standard). Thank you in advance Luigi "gix" ha scritto nel messaggio ...
