Guys, Does anyone know if it matters which terminal you attach the power to on the W58 series breakers? Near as I can tell there is not any positive or negative marks on any that I have. Right now I have wired with feed to the bottom terinals and form the top terminals wired to either the units or a switch. I also ran into a little trouble trying to figure out the low fuel warning switch that I installed in the header tank. The switch has only 2 black wires out of it. The only clue in the instruction sheet ( if you can call it instructions) is one side up is a normally open circut and installled other side up it is a normally closed circut. I figured that it was simply a interupted ground that the switch completed the circut. I tested it every way I could think of with a battery charger and couldn't get the light to come on. The light does work when it's hooked to the charger. Any ideas or maybe I have a bad switch. BTW hopefully tomorrow night the 3100cc corvair comes to life. The fuel is inthe tank and battery onthe charger. Thanks for any help-- Joe Horton
