So basically you hooked both wires to 12V - right? 
 
Yep, = but with the=20 diode that's shown in the = drawing.
 
Are you using a contactor and crowbar setup to = diconnect the B=20 lead in case of overvoltage? 
 
Nope.  Modern=20 alternators are reliable enough for me.  I'm also not so sure = that the=20 alternator can produce voltages high enough to hurt anything, except = maybe the=20 battery, eventually.  When I first hooked mine up, I put a switch = in the=20 circuit, thinking I could shut off the alternator.  All I managed = to do was=20 cause several different variations of unregulated voltage.  It=20 never went over about 18V, which is well within the range of what = most 12V=20 items can tolerate. 
 
Jusr curious - why not use the alternator warning since = it's=20 there. 
 
I = figured someone=20 would ask that :-)  I didn't want to mount another warning light, = since I=20 plan to have the (say it with me <g>) EM-2 watching the=20 voltage.
