Ronnie, If you are going to repair that alternator slip ring connection =
please give some serious thought to using a high silver content solder.  =
Sears used to sell it.  Use rosin core only, not acid core solder. FWIW.

  My IO 360's alternator is a Hitachi supposedly from a 1981-1987 Mazda. =
 It has an external regulator - I have a solid state VR600.  Right now =
it is down due to a broken wire in the field to slip ring connection.  I =
am going to try to repair it and replace the brushes which are supposed =
to arrive on Thursday.  This alternator came with the Don George engine.

  I see no reason why you couldn't use a built in regulator - as Keith =
states most autos now use built in regulators - it certainly improves =
your chances of finding a match from a more common automobile.   But you =
will have to find a bracket to match the Lycoming alternator mounting =
boss.  I'd favor the $200 kit from Velocity, it should also include the =
mounting boss and adjusting bracket.

  Bob Nuckols favors the external regulator and the overvoltage =
protection scheme he designed.  The advantage is that IF there was a =
voltage run away, it would minimize the damage to the high dollar =
avionics in your panel.

    Mel,

    Any "aircraft" alternator will not have an internal regulator, but =
just about every "automobile" alternator will incorporate a regulator.  =
I'm going with the B&C alternators myself, which are nothing more than =
Nippon Denso auto alternators which have been precision balanced and had =
the built-in regulator removed.  Yes, it's a lot of money, but it's hard =
to argue with their record of success!

      I purchased a B&C voltage regulator several years ago and intended =
to also buy their alternator.  Now I find that I no longer think that =
they are worth $600 to $700.  Velocity has a 60 amp for about $200 but =
it has the voltage regulator built in and I hear that it's a major =
effort to disable it.  Does anyone know of an alternator without a =
regulator that will fit my LYC IO360?  Also, what's the difference =
between a case mount and a boss mount?=20

      99.9% finished and taking for ever!!=20
