[DeTomaso] Relays, Fans, Ammeter, second thoughts and project expansion

[Tomas Gunnarsson]

Actually, connecting it that way ensures that all the energy consumed by
the fans has to pass the ammeter.

Pantera Electronics make great things, I have their white and yellow in
one
parking/signal lamp. But there is another way to get the fans away from
the
fuse block. I've taken power straight from the battery to the relay.
That
has four advantages, one disadvantage:
Advantages:
-Simple, as in you won't get stranded anywhere because of this
-Cheap, no purchase necessary
-Stopped my car from running on when key is turned off. I'm not educated
enough to fully understand why, but I was told so, and it works
-No extra juice/heat past the amp gauge
Disadvantage:
When the fans turn on, your amp gauge goes to the right instead of the
left
(This can be an advantage also, because it's a sure way to see when the
thermostat turns on a fan, I discovered it is turned on way too often on
my
car, will get a hotter thermostat for the fan)

Pantera Electronics has an amazing fan controller, power is removed from
the
fuse block.
Also, look at the replacement (plug n play) fuse block.

>>>The VofC mod involves adding a second fusebox to drastically shorten

improve the current path for the fans. The aux fuseblock is powered by a
large-gauge wire hooked to the back of the ammeter; power wires then go
from
that fusebox directly to the fan relays, which are still switched
normally. 
(The fans are grounded locally with diodes as well). The problem with 
that scheme is that the fans are powered all the time, and will run on
after

the ignition is switched off. Rick Moseley deals with that by adding
more 
relays, so the power from the aux fusebox to the fan relays passes
through
ignition-switched relays.
