Hi,

So I took the bait and ordered a Denso racing alternator from DB 
Electrical. Nice unit. Mounting it was a 1 on a scale of 1 to 10 with 10 
being impossible. Easy, peasey.

So, here's my question: the alternator is supposed to be 
"self-exciting". Once you get to 3000 rpm, the thing should turn on. I was 
expecting to see the system voltage jump up a bit to 13-ish when the 
alternator turned on, but that is not the case. I get ROCK STEADY 12.06 
volts from when I start the car 'till I shut it off.

Can anyone else whoe's done the conversion comment on the operation of 
this setup?

Maybe I should be looking to use one of the other spade lugs on 
the alternator to get the thing to turn on?

Alternately confused,
rml
