Dodge Lancer Voltage regulator
MOST modern replacements for the 69 and earlier regulators ARE solid state, HOW DO YOU tell? Easy. If it is about 1/2 as tall it is solid state. If it is full height, turn it upside down and look at the bottom. The original electro-mechanical ones had 1 or 2 wirewound resistors on the bottm. The solid state ones have no such.
