How do you tell your solenoid is bad?

The easiest way is to disconnect the power and apply an Ohm meter across the terminals. Depending upon the solenoid and the power source you should read something from a few ohms to a few hundred. This will vary greatly. If you read in the thousands or an open circuit it is probably bad. You also want to measure the resistance from the input wiring to the case. Again the reading will vary greatly. For a single wire solenoid like one found in a car, you should read the same as the coil resistance in the first part. If its an AC solenoid a reading between the two terminals is probably in the hundreds of ohms. When you test from wire 1 to case and wire 2 to case you will either read an open (meg ohms) circuit or an open on one and a short on the other. this is normal.

Last, you can always apply power and see if it moves. You should see and probably hear the center throw move.

Any solenoid is an electrical switch with main terminals to pass current when

operated by the small terminal being given a voltage .

to check if sol is faulty bridge the two main terminals with thick jump lead if the starter works its faulty.

If it still does not work check these with and without operating the key switch.

1.Good Battery voltage across battery terminals

2.Same voltage at starter

1 and 2 should be the same

if 1.2 check out ok you will most likel find the brushes in the starter motor have worn out

if the started doesnt do anything its the solenoid if it just clicks and spins its the bendix

Only by knowing beforehand its internal resistance, is possible to tell if it is bad, by measuring its resistance (DC current). If it dropped to a lower resistance it is short-circuited, and so it's bad. If the solenoid doesn't attract or attract with less power it is also a sign that it is bad.

A bad transmission solenoid will cause hard shifting and can eventually damage the unit. You should change the solenoid if it is bad.

Put a stethoscope or a plastic tube onto the solenoid, listen at it while a friend turns the starter. If solenoid clicks it is good. -Problem then is low battery or dud starter.

Good power all the way to the starter, 12 volts at solenoid/start circuit wire when key engaged, but no click or starter engage

User Avatar

The wire that goes to the starter button can be connected to the power wire coming from the battery. Just tough the wire quickly. If the solenoid engages the starter, then it is ok. If not, then there is either no power from the battery of the solenoid is bad.

take the cover off the solenoid put a screw driver across the 2 studs crank the engine if it starts your solenoid was bad

If your solenoid is bad on your atv raptor it will just click when trying to start it

User Avatar

If a starter relay or solenoid is bad, usually you will only hear a single click when you turn the key to start the engine.

Could possibly a solenoid on the starter going bad. Could possibly a solenoid on the starter going bad. Could possibly a solenoid on the starter going bad.

Good battery, good connections, starter will not engage, sometimes there will be a click, but not necessarily, if you can jump a wire over the solenoid terminals to the starter and start the engine it's a for sure thing.

User Avatar

If the battery tests good and battery cables are clean and tight at both ends and you are jumping the starter solenoid correctly with no results, you probably have a bad starter/solenoid.

When a shift solenoid goes bad the solenoid doesn't make any noise.

It is important to know the signs of a bad car part.The signs that a glow plug relay would be fast clicking from the solenoid, or no clicking at all.?รฆ

User Avatar

It could be 1 of 4 things. 1.Bad solenoid, 2. Discharged battery, 3. bad battery connections,4. bad connections at the solenoid.

Sometimes the cylinoid will make a loud whine or humming when engaged if bad but the best way to tell is to remove it and have it tested.

The solenoid is connected to the starter and for the backyard mechanic if one is bad they both are bad. When you purchace a new starter it will have a solenoid attached so dont worry. Getting your hands on just a solenoid for that vehicle might prove to be a chore. I'm having the same problem and wanted to ask the same question about a 92 Sable 3.8. I'm thinking that if you don't hear a click when you turn the key it may be that the solenoid/relay is bad. I checked my solenoid with a tester and it is getting juice so I still don't know for sure if it's the starter or the relay but I'm thinking more towards it being the relay because I don't hear any clicking sound that the relay usually makes... Can anyone expound on this and help me out??? I'd appreciate it... Thanks.

If it is the solenoid just take a small jumper wire and jump out the two small terminals on the front of the solenoid and the starter should try to start the engine. If nothing happens then it is bad. Or you could take a volt meter and go from ground to the starter side of the solenoid and get some one to take the key and try to start it ,if you get 12volts and the starter doesn't try to engage then your starter is bad ,if you don't get 12volts then your solenoid is bad.

will the solenoid in a car cause it to shut off like a bad alternator

User Avatar

Yes, but eventually your started will cease to work?

User Avatar

Seized Engine? Loose or corroded battery cables? Loose connection at starter or solenoid? Bad starter solenoid Bad starter? Bad neutral safety switch?

User Avatar

yes its bad go ahead and change it.

User Avatar

there is either a bad connection to the solenoid or the solenoid itself is bad
