Can a starter drop dead with no previous indications of it going bad?

Recently bout 6 weeks ago replaced the ignition switch. Kinda thinking this could be the neutral safety switch. How can I bypass for diagnostics?

To bypass, a battery cable is connected to the starter solenoid. The starter solenoid also has a small wire that activates the solenoid when this small wire is energyzed. The basic method to bypass the key switch circuit is to connect, tap for contact, between the battery wire and the small wire terminal.
Some starter solenoids are mounted on the starter motor, others may be located on a fender well in the engine compartment.
The starter solenoid relay is a remote electric switch. The starter uses a huge wire and amount of juice, so a relay is used so a small wire and small amount of juice is used for the starter key switch and other safety and security switches.

Hi Frank , what make vehicle ? Do you have any warning lights lit on the dash , SECURITY maybe ? Check engine light ? Did you check to see if there is battery voltage at the starter solenoid ? Did you check if there is A starter relay ?

    Hi Jeff. 1996 S10. All the normal lights come on like preignition. No check engine. I'm trying to do anything I can to keep from having to test the starter. It's the worst location for a starter I've ever seen and you literally have to loosen and jack parts of the transmission to get it back in. It's impossible to test the solenoid without removing the starter. I already tested the starter relay.

    You can use a jumper wire at the relay socket to see if the starter cranks ! On the relay it should be marked on the side or the bottom , with a diagram or pin numbers 85,86 an 30 , 87 .pin 30 is battery voltage ,pin 87 goes down to the starter solenoid . jump pin 30 to 87 if ok the starter will crank !

    Thanks Jeff. I'll try that when I get off work. Outta curiosity will tht bypass the neutral safety? Or is the 30 pin after the neutral safety on the wiring path?

  • Randy Ohler Apr 28, 2015

    No Frank it doesn't by pass the safety switch. It gives you direct power to the starter. To by pass the safety switch, you have to pull the plug from the transmission and jump wires for the safety part. Year make and model please. I have several on alldata, but i buy them and may not have yours. If I do, it's yours.

    Frank , the park neutral switch is on the control side of the relay 85 , you can test that at the realy socket too. with a test light or a volt meter . have someone turn the key to the start position an check for battery voltage at pin 85 .if there is battery voltage the park neutral switch is good an ignition switch too. You may as well check pin 86 for ground while you are there !

I have a 2004 Saturn vue...I replaced starter last year...but about a week ago I had to turn the key on and off multiple times and then finally starts...now it wont start...battery is good startergood


It's possibly the ignition switch or the battery cable going to the starter . Would need to do some testing to say for sure . Can you do electrical testing ? Have someone turn the key to the start position and someone check for B+ voltage at the S terminal on the starter solenoid . If B+ voltage is there , voltage drop test the starter circuit .

How do I check a ground connection ? My 1988 GMC Jimmy has a new starter and again it seems to free wheel and not start.Seems to help if I put it in neutral.


You could possibly have a bad park neutral safety switch , power ( voltage ) from ignition goes thru the park neutral safety switch to the S terminal on the starter solenoid . Does your vehicle have automatic or manual transmission ? And you should have voltage drop testing on the starter circuit done . Starter Voltage Drop You could have a bad battery cable .

Truck will not start, has lights, radio. But if I jump solenoid, it will start. replaced solenoid same thing as before. THIS IS A F-150, SORRY I PUT F-450

Dead battery


You have a random electrical short in the system and it is on the acc. side of your ignition system.Systems such as interior lights, glovebox light, brake lights, memory circuits for onboard computer, radio and some aftermarket components. Without me being able to see your car it is very hard to determine the cause. First determine that the battery is dead. Its possible that the battery cables have a bad connection, not at the battery but at the starter sol. or the battery cable ground connection on the engine. Clean these connections to see if you fixed it. If not then after that you will need to remove the poss. battery cable take a volt ohm meter and put the black lead to the poss. post of the battery and the red lead to the cable, set the meter to 10 amps BEFORE you hook it up. Then wate until all systems have timed out when this happens the needle will drop. If not then you have a direct short. If it does drop it should drop to less then 2 amps (that is normal) if it is above that you have a drain on the battery. Before you start this test make sure the key is out of the ign. then remove the interior light fuse that way you can open the doors without resetting the timers. Watch the meter and remove one fuse at a time, if the needle drops then that is the circuit that is giving you the trouble. Find out what that fuse controls and repair as needed. Hope this helps. Let everyone know if it did OK

2001 bmw wagon , last week would not start , could not jump either . 1. checked battery ? it was good 2. replace starter 3. worked for 2 days 4 now same symptons again will not start or...


it is a possibility that it is bad or the ignition switch. cause a bad ignition switch will not send voltage for starter to start. an ignition switch handles a bout 50% of all voltage needs. the safety switch does it start in nuetral, or any other gear! if it starts in any other gear then it is out of adjustment. or needs replaced. first check and see if you have voltage from battery to starter, if so, check small ignition wire at starter. either wire could be bad also.

I have a 2004 hyundai accent. the starter went bad two weeks ago, and a friend and I replaced it. (it wnt without warning ) The other day, it went again. I'm told it could be in the ignition. That it's not...


if this starter "went bad" by refusing to work (run)
replace your ignition switch: it's behind the ignition lock on the steering column.
ignitions do not tell starters to do anything: the ignition switch key turns the starter on and, a spring returns the key to off when you release it turning the starter off.

Could be a poor connection on one of the battery terminals - be sure they are tight.
Could also be a starter solenoid that is sticking.

Voltage drop testing the starter electrical circuit would be a good first step , ruling out the cable's connections an ground !
Starter Voltage Drop If this doesn't find a problem ,then check the control side . Ignition switch , when it won't start check for Battery voltage at the connection at the starter solenoid "S" terminal .
