The solenoid has 2 big cables one goes to the battery and the other to the starter.
the small wire that has a boot that pushes on to the screw is the control to close the solenoid.unless the solenoid is shorted,the starter should not run

    take off the small wire on the post on the solenoid and it should not turn over.the ignition switch may be bad and it is giving 12v to the post that switches on the solenoid.

1993nissanpickup d21try startin but just click new battery


check your ignition switch solinoid, it could be shot or check your starter relays and fuses, check the theft prevention switch just under the ignition cylinder. there are multiple things that could be causing this problem, but if your like me, you can just bypass all the starting relays for the starter and run a switch inside the cab to push that runs directly from the battery to the starter, and install a push-start button on the dash. let me know if this has helped you any, good luck.

How do you wire a 1981 ford f150 starter relay?


The standard Starter relay has 2 mounting holes then you can see it has 2 copper studs 5/16 diameter one goes to battery positive and the other goes to the starter then the 2 smaller studs have letters indicating there power source "s" and "i" S stands for start this wire comes from the ignition switch The I is ignition bypass wire and is only used on point ignition and early solid state ignition systems . on 1981 it is not needed.

I lost my starter and now I can't start my car! Help please!


If is automatic ,you need to install another starter , but if is stick shift , you can push start it, you need to have a few guys pushing the car ,while you are behind the wheel, with the clutch pressed in and the ignition swith on, when the guys are pushing the car a little fast, let the clutch go and give it a little gas, it should start that way.

I have an 1989 jeep comanche. It had an ignition switch bypass. I took it off and replaced the switch and the relay. If i touch the positive battery cable to the green starter wire on the relay it...


on the relay there will be a small wire that gets power when you turn the key to the start position
find that wire and connect it to the small terminal of the starter solenoid
then if you get it right , when you turn the key to start, power will get to the starter solenoid , energize the solenoid and the starter will engage

I have a 1993 buick lesabre. The security light is flashing and will not start. I checked the fuse it was ok. I tried our other key and still wouldn't start.


there may be a broken wire from the ignition swith going down the steering column,theres two sensors at the begining opening of switch, sometimes they get stuck and dont pop back out, in turn it doesnt touch the chip on the key and cant read it,take a look with a light use a small pic and push lightly on them and see if the y push in and pop out, if they do then replace ignition swith,theres a way to bypass,use an omh meter and measure resistance of key chip, then buy a resistor with the same value,and connenet to wires from switch under the dash,cut wires and put conecting the two going to switch with resistor connecting them together,heres a diagram,193b32f.jpg

I need a simple diagram on how to install a push button starter switch using a toggle switch, push button and resistor. The only thing I need is to start the car. Its an old VW and I want to bypass the...


its hard to provide a schmatic without pictures but here is what you would need ... i assume you are using a three position toggle switch with a spring loaded position for start ... all contacts would be off at first .. contact #1 would be off, on , on ... that would switch 12 volts to the ignittion ballast resistor that is in series with the coil (normal running position).. contact #2 would be off, off, on (spring loaded) ... that would jumper the ballast resistor only for starting (that compensates for normally low battery voltage while running the starter) .... the third contact would also be off, off, on (spring loaded) . that would cnnect 12 volts to the starter relay .. that contact would have to be rated for the current drawn by the starter relay .... if you wanted a different switch arrangment ..like a toggle switch for ignition and a seperate push button for start .. then the ignition toggle would just provide 12 volts to the balast resistor that is in series with the coil ... it would only need one contact off,on .. the push button would have to have two contacts both operate at the same time .. one conntact would jump the balast resistor when on (start) .. the second would provide 12volts to the starter relay.. the second switch configuration might be easier to find than the first ...

I cant figure out how to wire a push button ignition on my 1985 ford f-150


If you're looking for wiring a push-button starter, then you just need to connect one terminal of a momentary type switch to the solenoid (little) post on your starter, and the other wire to a ground source. This will only crank the engine, so you would need an additional switch, or the actual ignition switch to switch on the accessories, and the ignition system.

By pass ignition switch


If your ignition switch is bad in your steering column, and the starter does not engage when the key is turned forward, then this is a quick fix for you.
BE SURE THE BATTERY IS DISCONECTED BEFORE YOU START WIRING. You can run some heave gauge (18 plus, and about 12 feet of it) wire to the top mount and the rear mount on the starter solenoid (one end of the wire to each, making a loop) Run the wire into the interior of the truck, and then install a toggle switch in the loop of wire. You will still have to turn on the key to engage the motor, but it will not start until you flip the toggle. That should get you by until you can replace the ignition switch in the column.

Starter switch


You'll connect one side of the button to constant 12v. like the battery positive and the other side of the switch will go to the trigger wire of the starter. This is the wire that tells the starter what to do.

Blown fuse - What's it protect???


in what country ?
My '89 2.3 liter Isuzu pickup
NO TRANSMISSION STATED (auto or stick)?
fuse are to prevent FIRES
ever see a wire burn red hot and then melt a fuel line (ugly *****)
fuses on cars with fuel are serious.!
lesson 2 is There are not 1 fuse for every load in a car, or you'd have 100s fuses.
lesson 3, the power distribution is a tree with branches fused.
same deal on cars, trains, boats and planes.
for the same reasons
my wild guess1
you work with no 89 2.3 liter schematic the proceed to hack it and find fuses blow. sure.

so my guess 2 is you bypassed the starter solenoid ?
and overload that circuit.!
the relay has purpose, its a current buffer (lesson4)
the reason car didnt crank
is the relay
the blk/white wire uses like 8amp
current is buffered by the relay to 30 times less.
This less current save you from burning up and expensive
ignition switch, (some are $100)
that 5 relay saves 100 bucks. and repeats.
the relay also us for logic
the USA laws mandate a park /in gear lock out
so the relay did that, at blk-pink wire.
now defeated. by you.
try a new relay (if hacking is a goal)
and put switch to ground (pin1,) and pin2 of switch to
brown -red wire on new relay. bam starter fixed
and no burn burned up ignition swithes or fuses.
see fuse 12 below. 10amps
that fuse can not run a solenoid direct, the relay must be working.
the starter solenoid uses a 60amp fuse. blk wire (main).
