[VAC] Re: Why Car & Trailer Battery to Univolt?

[Chris Bryant <bryantrv@xxxxxxxxxx>]

         Personally, I like relays better than diode isolators- but both 
systems have their proponents.
         Tekonsha makes a continuous duty solenoid that should be available 
at any RV dealer for around  $13- they don't have an amperage rating, but I 
would make a swag that it could handle 50 amps very comfortably.
         For something heavier, Intellitec makes a relay system (several) 
that senses the charging voltage, and doesn't engage the relay until the 
voltage is above 13.3 volt, and one that uses a diesel starting solenoid, 
but reduces the coil voltage to (IIRC) 4 volts or so, so that an 
intermittent duty solenoid can be used for continuous duty.

Managment" from the drop down menu.
