Stalls with electrical loads

The factory values for the coil resistors are in the back of the electrical section of various shop manuals. Once again, you can download those at MyMopar.

The '73 book shows .5--.6 for the COIL side and 1.6--1.79 for the ECU side

My 67 (points) book shows same thing.......... .5--.6 ohms
