"[...] you may need to rev the engine a bit higher than normal to get
the alternator kicked in due to the different coil loading the
activation-warning light circuit."
Second that. I have two (2) Stancor 120-901 "contactors" (relays)
connected to the blue wire (one of which connects the alternator to the
cabin battery, the other provides an auxilary +12V for a control voltage
for another application). Each contactor needs 3/4A to pull in for a
total of 1-1/2 amps. I have to goose the engine a bit after starting to
get the alternator light to go out and pull in the contactors.
BTW, these Stancor parts have been very very reliable but have exposed
terminals which makes it important to make sure that nothing can short
against them. Data sheet at
<http://www.stancor.com/pdfs/Catalog_2006/Pg_052_53.pdf>. See them big
posts on the top of part? That's where your battery and alternator get
connected.
