To Group,
I am having issue’s with  the starter wiring.
I am using an after  market ignition switch
from the auto parts store. It has four terminals
on it. They are marked as follows; Batt., Acc. ,
Ign., Str. There were no instructions in the
package. I also have an amp meter that ties
into the ignition switch. I have power from the
buss to the Batt. terminal, and I have another
powered wire from one side of the amp meter.
This second wire is as per the amp meter
instruction, only it does not say which terminal
to attach it to; so I have put it on the ignition
terminal. The third wire involved in the switch
goes from the terminal marked Str. to the starter
solenoid.

Now the problem; when I turn the ignition
switch to start, the engine will turn over. This
occurs regardless of whether the primary buss’s
switch is on or off. I know that the wire from
the amp meter is hot, so I probably have it
connected to the wrong terminal; only which
one does it go to. Any suggestions.

Use an ohm meter to check out the key switch and see what terminal becomes
hot when you turn the key to start.  Now connect that terminal with 16 gage
stranded wire to the starter contacter. That is the small cylindrical
device on the top
of the starter. The contacter is just a heavy duty relay.


The key switch is connected to any source of 12 volts.

Al least one terminal connects to all others from time to time
depending on the position of the key. That is the common terminal
and that is what is connected to the 12 volt supply.

A push button switch on the instrument panel will work as well.

Let's amend that test to using a meter set for Volts not for Ohms.
