Why does my starter terminal not have power?
That terminal wont have power unless the key switch is turned to start. In other words the wire with the angled boot is the power wire that triggers the solenoid and connects the power from the battery to the starter. When you release the key it cuts the power to the solenoid, releasing it, thus cutting power to the starter.
Which is the ground terminal on a fuse box starter relay?
The “S” terminal (or 85 terminal in some relays) receives a 12-volt signal from the car’s battery. A small current, usually less than 10 amperes, passes down the terminal and through the coil windings and through to ground. In the fender-mounted relays, this is the “I” terminal. In fuse box starter relays, the ground is terminal 86.
Where do I find the voltage drop on my starter?
If you don’t get a good reading, check the terminal connected to the battery post. On starters with a remote-type solenoid (relay), check the voltage drop between: The positive battery post and the terminal connected to the starter terminal on the relay. The positive battery post and starter terminal on the relay.
Can a blown fuse cause a starter to not start?
Blown fuse – Sometimes the simplest explanation is the best one. A blown fuse in the starter circuit could be the cause of a no-start problem. Broken or corroded wiring – Damaged or dirty wires to the battery or to the starter solenoid (or wires that are loose) can prevent sufficient power from reaching the starter.

How to test for voltage at starter wire?
Start with testing the fuse for voltage. Fuse 9, in the engine fuse box. Then push in the clutch, or if alone, place a stick on it and the front of seat, or jump the switch, then test for voltage at the relay. Then and only then, if you have voltage at the relay, the relay is bad, but first check the ground.
Where does the power come from on a starter solenoid?
The power on the small wire at the starter solenoid comes from the key switch, and may or may not go through one or more security systems. First, you can verify that you have battery voltage going IN to the key switch. If not, it’s a fuse or wiring causing the voltage drop.
What should I do if my starter switch is not working?
If your solenoid is a four wire solenoid, check both small wire terminals as one is ground and the other is power from the ignition switch. *If your solenoid is a three wire solenoid, make sure the solenoid body is not corroded where it bolts to the chassis of the mower as this is your ground path back to the battery.
How is the solenoid connected to the starter relay?

When you release the key it cuts the power to the solenoid, releasing it, thus cutting power to the starter. Last edited by gregpro50; 04-04-2008 at 05:14 PM . Midland ONT. CANADA
Why does my new starter relay not work?
Brand new starter relay works because I jumped the small terminal and the car cranked over. However, I noticed the last time car cranked over fine with the small terminal connected there was a little smoke that came from that same area. I am guessing I blew a fusible link or burnt a wire that is somehow wired to that small terminal.

When does the power wire go to the starter?
The other goes to the starter and is only hot when the solenoid is engaged, which is when the key is turned to the START position. The small wire is the power wire that energizes the solenoid when the ignition switch is turned to the START position by the key.
Is there no power to starter solenoid wire?
Has power to all accessories but will not even turn motor over. Checked all the normal signs. it has… wire to starter solenoid is not cut, but has no power going to it when key is in start mode. any ideas?
How does a starter work on a truck?
What’s called the “starter” has 2 power connections – a large wire that provides power to the starter motor, and a smaller wire that powers the starter solenoid. When the key is turned to start the solenoid will engage the gear on the starter with the ring gear on the flywheel as well as trigger the starter motor to begin turning.
Why is there no power on purple wire in start position?
If there is no ground getting to the starter relay then the computer is not energizing it. Typically when this occurs it is due to the computer not receiving a signal from the ignition switch or from the transmission position sensor.
Why does the light go out when the starter goes on?
If light goes out when starter runs on, its the switch in the solenoid. If light stays on when starter runs on, theres something amiss in the ignition switch, ignition lock, wiring department. Coco is right. Let me explain a little bit further.

How does an ignition system work when there is no distributor?
When an engine has no distributor, it will use a sensor on the crankshaft to identify each firing event; the sensor also recognizes the number-one cylinder. The control unit is programmed with the correct firing order.
Why do I have no spark in my ignition?
More complicated issues may also contribute to spark loss, but basic conditions are still the general means for good function of any ignition system. Knowing what to look for when troubleshooting ignition systems can allow proper decisions to be made when selecting repair procedures or replacement parts.
Why does my starter solenoid not have power?
Yes, when the ignition switch is in the START position, the small wire on the solenoid should have power. That’s why I think your problem is in the ignition switch. If the ignition switch isn’t making contact in the START position, the solenoid wouldn’t get any power.
What to do if your starter wont turn on?
If you don’t have power you will need to gain access to the neutral safety switch (A/T only) and test input and output power. If you have power in, but not out. Confirm the car is in park/neutral before replacing the switch. The power input pin in the ignition switch draws power directly from the battery with no fuse or fusible link seemingly.

What are the causes of starter system problems?
Common Sources of Starter System Problems 1 Loose electrical connections in the starting system 2 Dirty connections 3 Corroded battery terminals 4 Worn out or failed starter system parts
When do I need to replace my starter motor?
So, if this happens the starting motor will have to be replaced. The most common problem with a starting motor is, when you turn your key and nothing happens. A solenoid or motor that has burned out or electrical issues, may cause this as well. Furthermore, a dead battery can cause the same problem.
What to do if your starter relay does not have power?
If you do have power, pull the fuse and probe the terminals that the fuse plugs into to see which one has power. The one that does not have power is the wire going to your ignition switch. Set your multimeter to Ohms to check continuity.
