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

How do you tell if the stater solenoid is bad or not?
if the started doesnt do anything its the solenoid if it just clicks and spins its the bendix
How do you tell if a solenoid is bad?
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.
How do you tell if starter or solenoid 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.
What will a bad transmission solenoid do?
A bad transmission solenoid will cause hard shifting and can eventually damage the unit. You should change the solenoid if it is bad.
How can you tell the starter solenoid is bad?
Good power all the way to the starter, 12 volts at solenoid/start circuit wire when key engaged, but no click or starter engage
How can you tell if a solenoid is good on a go kart?
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.
How do you tell if starter relay is bad in a 1995 Dodge Spirit?
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.
How do you know if the solenoid is bad on a Yamaha raptor ATV?
If your solenoid is bad on your atv raptor it will just click when trying to start it
My alternator is not getting power from the battery The wiring from the battery to the solenoid and from the solenoid to the alternator is good is this a bad solenoid the car will start and run?
Check for a bad fusable link at alternator
Why wont starter engage all the time when i turn on the key on a 96 pa?
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.
Does a bad solenoid smoke?
It can as it is an electrical part
Is a starter bad if you jump the solenoid and nothing happens?
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.
