RE: [DML] Alternator upgrade troubles



Ryan,

It may seem a dumb question but do you really NEED a 180 Amp alternator? In
general the higher the Amperage output the higher the RPM that is required
to trigger the regulator into the charge mode. Also the greater the wear and
tear on your poor alternator belt which DeLorean's are already known to shed
somewhat often. It probably won't start to charge much before 2000 RPM
making it impractical for anything but straight highway use. Short of major
power robbing accessories I personally think an 110A alternator is the best
optional size for the DeLorean. Why are you stuffing an alternator into your
car that is so oversized compared to your cars actual requirements? Am I
missing something or are you having a "mine is bigger than yours" contest
with someone? :) Just kidding...OK!

Folks,

I bought & installed a new 4-wire 180amp alternator tonight. It's
mounted up great and the belt is turning it just fine but I'm getting
NO power from it! I could really use some advice...

I had an original motorola alternator. There were only two connections
to it: The main power feed (8 cables going into 2 ring connectors
hooked up to the primary "batt" terminal on the alternator) and a
brown wire that goes hot with the ignition on, which I assume is the
sense for the regulator.

There were NO other wires connected to my Motorola. I was instructed
to hook up a yellow wire for the lamp light to the "L" terminal on the
new 4-wire plug. I looked all over the place but couldn't find a
yellow wire, nor any loose wires whatsoever.

So, I mounted the alternator, connected the main power wires to the
primary power terminal and connected the red "S" wire on the new
4-wire plug to the brown wire. I left the other three wires in the new
4-wire plug disconnected.

I get nothing. Zero voltage output. :(

Any ideas?? If it's just the lack of connecting the "L" wire, can
someone tell me where in the world I should start looking for that
wire? Where does it go or route from? Which wire loom does it come out
of? As I said I looked all over the place, it's not to be found
anywhere...

Thanks for any help,

-Ryan
