10.5 milliamp drain on battery

["Robert McBride" <rmcbride@twmi.rr.com>]

As I'm getting closer to getting my 76 on the road again, I need to tackle the
10.5 milliamp drain on the battery that drops down to 1.6 milliamp if I pull
the single wire off the alternator and goes to 0.0 when I also pull off the 3
wire plug....  Sounds like a bad diode right???  Anyone have any luck finding
spares and replacing them???  Bob
