I have a B&C Model BC460-H alternator and would like to know if there is an automotive replacement for it in the case of a failure away from home. I?m looking for the exact form factor that would allow me to go to an auto parts store and purchase one and replace the faulty B&C in order to get me home. This model uses the B&C external regulator. I used to run the auto alternator (Suzuki I think) but decided to replace it with the B&C when I upgraded the panel for IFR. The old auto alternator isn?t the same form factor and wouldn?t just bolt back up. Has anyone else thought of this scenario? Thanks David
