Hi there,

OK so the alternator went bad in my 85 Volvo 240 GL.  Went to the wrecker,
and found two 240s, an 81 and an 84.  My 85 is a B230F engine, these were
both B21s.  I did take the alternator from one of them, and put it into my 85,
and it seems to work fine.  THere was a size difference, but upon doing some
research, discovered they are both 70 amp, and both have regulators on the
alternator.  Both have the same bolt pattern and tensioning method.

Can anybody thing of any adverse effects to putting an alternator from a
different motor onto my car?

I tested the voltage once installed, and it was at 13.6volts.  When I brought
the alternator from the wrecker to the local autoparts shop, it tested good.

Any thoughts?
