/I received my new Key West Regulator and have a couple questions.
/First, the new reg is not heat synched with any cooling fins. I
/plan to mount it on the inside of the Firewall directly to the inside
/padding. Should it be mounted on standoffs to provide some air flow
/in behind it? Don't know how hot the thing gets.
It DOES heat up . . . check the instructions closely. Make sure
they don't recommend mounting against some metal surface. Many
power products that don't have fins depend on metal mouting surface
to to reject heat.
/Second, does the SS provided noise capacitor hook up the same?
Yes
/Third, the schematic provided by Key West shows two ways to hook
/it up. One with and one without a Battery system. The Battery system
/hookup shows hooking the output of the regulator directly to the A/C
/Battery and not through any switch. This method provides no
/seperation in case of failures in the battery or the regulator.
Bad idea . . .
/ I plan to bring in the battery power through a master solonoid and make
/ the connection to the regulator inside the A/C. Doesn't this make
/ more sense? This way, you can kill the master solonoid and still have
/ regulated power available from the regulator. With another regulator
/ switch, you can kill the regulator and use battery only. Seems like
/ the best of both worlds. What do you think?
I recommend that ov protection be included . . . those regulators CAN
fail and they'll drive the bus voltage right on up there . . .
A small (1 cubic inch) 30-amp relay can be added in series with the
regulator output and controled via switch and circuit breaker just
like on big airplanes. A crowbar ov module across the relay coil
will provide automatic shutdown of a failed alternator. I can
supply schematics and bill of materials to anyone who will send me
their mailing address. I also have ov modules assembled and tested
for those who choose to buy rather than build.
