Usually a sign that one or more of the circuits in the electrical portion of
the ignition switch is not making good contact. The switch can be replaced
separately from the lock section.
Ignition Switch 77-95 P/N 964.613.012.00 $50.77
Terminal numbers on the switch correspond to circuit and bus numbers in the
There are three circuit 30 terminals on the switch. These three are common to each other. With the switch in any position, there should be zero resistance among any of those terminals.
There is one terminal P, that is common to terminal 30 when the switch is in position 0 only
There is one terminal R, that is common to terminal 30 when the switch is in positions 1 or 2 only
There are two circuit 15 terminals on the switch. These two are common to each other. These are common to terminal 30 when the switch is in position 2 or 3 only. (for engine-run loads)
There are two terminals X on the switch. These two are common to each other. These are common to terminal 30 when the switch is in position 1 or 2 only. (for high-current accessories, drops when starter is engaged)
There are one circuit 50 terminal on the switch. This is common to terminal 30 when the switch is in position 3 only. (cranks the starter)
In addition, there is an internal switch with terminals labeled 1 and 2, used to indicate when the key is actually in place in the ignition lock. These two terminals are connected when the key is inserted.
The ignition switch position zero is the key-insert position, no travel
Position 1 is the "accessory" position
Position 2 is the engine-run position
Position 3 is the starter-crank position
