    I couldn't find my pictures, I think these came from B&C or Atlee Dodge.

    Is this an STC for an internal regulated alternator?

    update info from Oshkosh: The B&C Alternator BC400 is now STCed for most shortwings, regardless of the oilcooler position. Unfortunately it is fairly expensive at 850$. This price includes the bracket and the regulator.

    I talked to B&C and was quite imprssed with the design of the oil cooler brackets that come with the kit. Have modified the existing brackets I think it is worth the extra money.

    I installed the B&C alternator in my PA22/20 160. The new bracket is very robust and the whole system is well worth the money. Ill send pics in the next couple weeks. Very easy installation.

    It sure looks like you could save a lot of weight going from a generator to that alternator, and from the stock starter to a lightweight version....15 lbs maybe?

    Saving weight is great but a person needs to keep an eye on the W&B. I have seen lead added to the nose on other airframes because someone switched to as many light weight engine components as they could. Weight is weight so it doesn’t matter if it functional weight or dead weight but functional weight doesn’t take up extra space or need a new mounting system to be there.

    I have seen that one time. But that was when they de-mil ed an old P80/T33 and moving the batteries up front was not enough in the nose
