Small terminal on starter solenoid- if Ford product and have 2 smaller terminals - pick either - disregard 2nd small terminal
It is the ignition wire. The purple wire goes to the small stud on starter.
change the ignition starter switch
how do you connect the wire from the alternater to the starter?
The small purple wire on the "S" terminal of an older GM vehicle starter would lead to the ignition switch. With the key in the start (crank) position, the purple wire signals the starter solenoid to engage the starter.
The ignition wire in a Nissan 350z is black and red. The starter wire is white/red and the second starter wire is white/green.
Starter Relay Test Place transmission in Park. Apply parking brake. Check for battery voltage between starter relay battery terminal and ground. Connect jumper wire on starter relay between battery and ignition terminals. If engine does not crank, connect a second jumper wire to starter relay between ground terminal and good ground and repeat test. If engine cranks in step 3, transmission linkage is misadjusted or neutral safety switch is defective. If engine does not crank in step 3, starter relay is defective. Follow this step by step and you will pinpoint the problem.
purple is the trigger wire for the starter. Yellow is the ignition wire.
The proper way to connect a second starter wire depends with the configuration used.
you can try to short the starter motor . take a screw driver and bridge ffrom battery cable on starter to ignition wire on starter. if starter is good, engine will crank. if starter is bad , solenoid will click if no clicking, solenoid is bad
You need to determine whether your problem is a "no crank" problem, or a "no start" problem. To determine if it is a "no crank" problem, you will need to make two jumper wires. The first jumper wire should be about 6"-8" long, clips on either end, about 18g wire. disconnect smaller gage wire wire on the starter solenoid and jumper it with your jumper wire. Turn the ignition key on and then using another heavy gage (about 10 gage) wire, go directly from the positive terminal of the battery to the terminal on the starter where the battery wire connects. The engine should crank over. If it does not, replace the starter. If it does crank over, then you don't have a "no crank" problem, you have a "no start" problem, in which case this may be an issue with the alarm system. I goit lucky in that my problem was the starter, and not the alarm system. I performed the trouble shooting that I described above to determine that it was a bad starter. I replaced the starter, and all is well!
If you know the battery is good, then you have a bad ignition switch or starter, or a loose wire.
If you can crank the engine over by turning the key: First connect a voltmeter and an ammeter. Then disable the ignition. Note the voltage and amp draw of the starter while cranking. If voltage is too low or amperage too high (check service manual for specifications) it is bad. Otherwise, remove those meters and use an oscilloscope to look for any irregularities in the waveform. If any irregularities exist, the starter is bad. Otherwise, it is probably good. If you cannot crank the engine: Check for BatteryV- at the body of the starter, BatteryV+ at the big wire to the starter and (only while turning key to crank) BatteryV+ at the small wire to the starter. If one or more of these is not present, correct this problem before continuing testing of the starter. Now check that the starter makes some sound (at least a click) while turning key to crank If not, starter solenoid (part of starter) is bad. Otherwise, remove starter from engine but leave electrical connections in place. Turn key to crank. If it doesn't crank, starter is bad, otherwise starter cranks and proceed to testing as if you can crank the engine by turning the key as described above.
