    Alt. signal wire

    From page #1 of the original problem: (Alt sense wire cooked) My first thought was that the voltage regulator was shot!

    Felpro os34510T This is the one with two dipstick holes and does NOT seal on the Dr side rail. The felpro 1881 would work?? but is cut out for a stroked block removing 1/3 of the sealing surface, not good in my eye. The one I just removed (Black silicone rubber) has "NPC1" "MN3981" cast...
