I have a 1955 Chevy 235 engine and when I turn the ignition to start the car ,,the starter hesitates and then takes hold ,some times ,many times right after another before it engages and stays engaged long enough to start the engine .. I am asking how to determine which of the two are faulty before I buy one or the other .

It really doesn’t matter if you’ve yet to pull them off the motor. They come off as a pair. Once off it becomes easy to troubleshoot the two. Just make sure your not going down a rabbit hole. I had the same issue this spring. After way too much work, found the ignition switch had burnt contacts.

So, I take the solenoid off the starter leaving the starter connected up to the motor and then check the solenoid and relay for continuity of each to determine which one is bad.?
.I will take a look at the ignition switch first..

Does the starter spin but not turn the engine or does it click & not turn the starter?

The starter does not click .It spins .but only after it starts to connect to the fly wheel.. after a few tries it takes hold enough to turn the engine over and it starts

Sounds like you have a weak spring....assuming all your connections are good.

You don't have a starter relay and a solenoid. They are the same thing. You probably have a bad/weak battery. When it does that, jump it and see what happens. There are TWO models in 1955. 55.1 and 55.2. Which one do you have?

The starter is not supposed to spin until it engages the flywheel. So it's working correctly.

Don't mix your guess in with symptoms. Report your result after jumping. Then we can move forward with next test. Be sure you jump it with a good battery and check your battery posts and cable clamps. Take off and clean really good. Check cable and wires to starter. Check carefully.
Tell us anything you have done electrically lately with wires, battery, cables, solenoid, ignition switch...........

Don't remove starter or solenoid. That's later. Use a volt meter on battery. Touch only the posts and read. Then touch only the clamps and read. looking for 12.6V.

The only relay you have is a horn relay which also acts as a hot terminal block, sometimes, and may look like it's energizing starter.
Fords have actual starter relays.
Generally: a relay has no external mechanical linkage and a solenoid does. Their electrics operate basically the same. So confusion results.

bartamos. thanks for the help with the wiring ,,it is in and works fine except I might have gotten the wrong oil temp sender. that can wait ,,as now I want to fix the starting problem I have and had before I wired in the turn signals thru the ignition

I just went out and read my battery amps and it is at 12.55 ,,I put my slow charger on it and after it charges up to 12.6 then I will check the cables to the starter ..

I have a car motor 55 Belair ,,guess you were talking about the two years of PickUp styles with the 55.1 and 55.2 ..if not then you'll have to enlighten me..

Ok, glad I only have one relay or solenoid.. After getting all the wiring put in and tested to work properly ,,I then charged the battery to full and it is down some to 12.55 from a full 12.6..



Thats all I can come up with for now about any changes ,and like I said it did this same thing last June when I drove it last,, I do have a good battery to jump the one in the car ,,but need a helper and my son flew back home last Saturday ..

OK good. 12.55 is close enough. It could still be bad because they show 12.6 at static (no load) then break down under the extreme load of starter.
Yes, I was speaking of 55.1 55.2 trucks. Wanted to look at the correct schematic in case there were changes. If a car motor has something different than what I said, I don't know it.

I still say battery or wires/cables/terminals/clamps/connections/corrosion/, lead/copper sulfate.... The jump from another battery is still necessary. A helper is not mandatory. Pull other vehicle close, hook up cables and start motor. Stop motor, get out and disconnect. The posts and clamps MUST be thoroughly cleaned. The idea is to see if starter suddenly acts normal whether it starts the motor or not.

You can also take the battery to two different places. They will put under load and test. Don't trust one place/machine/operator. O'Reilly's, Autozone, etc do it for free. In or out of the vehicle.

So many times I have seen myself and others struggle when it was the battery or it's connections. It will fool you. So we must be 100% sure before blaming something else. This includes battery ground to the motor, ground to body and frame.

I think you might get a further hint if you turn on the dash lights before hitting the starter. If the lights blink or go out, you have a connection problem or weak battery.
