Blowing voltage regulators

@67Dart273 This is actually the Standard motor products VR101 that is of the traditional mechanical type, it could be adjusted but I don't either think its the problem as I have blown 3 already.
I did the first test of the field current draw test where it says to measure voltage drop between battery and VR field terminal. This should not be more than 0,55v, I have 1,01v. Now then it says to go through the connections on the route to the battery and find where it changes significantly, that was the IGN terminal on the VR where it is 0,6v drop. If i i unplug the IGN terminal from the VR and measure directly from the IGN connector I have 0,1-0,2v drop. The voltage is almost correct if the VR is unplugged, is this normal?
