Ford NAA-311006 Solenoid

I recently purchased the 311006 solenoid and installed. I have 12.64 VDC on one small terminal and the other small terminal is grounded. Is this enough voltage to work the solenoid?
 
(quoted from post at 14:32:55 02/19/13) I recently purchased the 311006 solenoid and installed. I have 12.64 VDC on one small terminal and the other small terminal is grounded. Is this enough voltage to work the solenoid?
hould be.
 
a 12v solenoid will usually pull in at about 9-10v and not drop out till 8 or under.

what problems are you experiencing?

have you done a bench test on the solenoid using a known good battery and some jumper clips and an ohm meter?
 
If you have 12.64V on one small terminal and the other small terminal is connected to Ground you should hear and/or feel the solenoid click as it engages.
 
This was going to be my next step. I recently replaced the old 6V solenoid with the 12V(previously converted to 12V system). I have one small terminal connected to the key switch and the other connected to ground. When I check the voltage at the small hot terminal, I have over 12V, but the solenoid does not close. I have checked my connections and they are good.
 
do you actually have the correct solenoid, and not a bypass slenoid, and have the bypass side hooked up?

try this.

hookup bat to both the big posts.

hook ground to case

probe either small post with wire from bat.

if it clicks.. it's the wrong one.

if not, try bat / ground on the small post.. ethen reverse them.

There"s lots of chinese junk out there now. This same problem shows up regularly on the Mustang forums.

I tried that same solenoid when I converted my NAA to 12 volt. It's not the right solenoid and will not work with the neutral safety switch. The correct solenoid with the isolated base I found was at NAPA solenoid number ST542.

ery interesting experience that you had, Kris. NAPA cross references 311006 to ST-542, both 4 terminal isolated coil units. :?:
 
Sure was a nice experience. I have the supposed to be (311006) sitting in the garage on a shelf and it is not an isolated coil.

How I wired the ST-542

Left large terminal ~ connected to starter
Right large terminal ~ connected to battery
Left small terminal ~ connected to ground push button
Right small terminal ~ connected to positive key switch

When the 311006 was wired this way and the key switch was turned on the solenoid was activated without pushing the ground button.

So if they are supposed to be the same solenoid I must have gotten a mis-packaged 311006. I'm good for getting the 1 out of 1000 products that's packaged wrong. Happens to me quite often. :wink:

pparently mis-packaged or NAPA book wrong!
 
NAPA's book is probably right, I'm good for getting mis-packaged products. Not the first time for me and I'm sure it won't be the last.
 
Tested the 311006. I removed the harness wires from the solenoid and the placed the ground under the mounting bolt of the solenoid. Fixed a jumper to run from the positive battery post and placed it on the I (small terminal first). Nothing happened. I then placed the jumper on the S terminal and the solenoid closed and the starter engaged. Just for understanding I then grounded the I terminal and placed the jumper on the S terminal. The solenoid chattered. I received this solenoid from a tractor parts supplier. All the numbers indicated that this was the correct part for my tractor, my luck also.

" Just for understanding I then grounded the I terminal and placed the jumper on the S terminal. The solenoid chattered. ",,,,,,,,that does not make sense for any solenoid...right or wrong type. "I" is an open ended circuit until the solenoid is pulled in. You don't have the wrong type, it is a defective part & further, even if the wrong part, to function like your description, it would still need to be a defective part.
 
To me the solenoid sounded as though it chattered. The starter did not engage, the solenoid was not continuously closed. I am planning on trying the NAPA ST 542. I will let you know what happens. I know that the part could be bad out of the box and anything is possible. But I received this part from a supposedly quality tractor parts dealer. This issue makes me even more timid about dealing with suppliers.
 
and wrong part IMHO.. but not defective..


he grounded the base of the solenoid then hit S with power.. solenoid engaged. that's wrong part.. not an iso base. my guess is it's a bypass solenoid

he then added a ground to I and hit S with power and solenoid chattered.

why?

when solenoid pulled in with S being powered.. then there was a ground present common to battery, menaing ground present common to that jumper to S.. and that probably kicked her out.. which broke ground path and let her pull back in.

sounds like a ignition bypass solenoid to me..

ay be.....but I'm not there to see his lash up. He did say it "pulled in & ran starter", so sounds like big honkin battery cable connected & I can not imagine that little finger inside that picks up power for the "I" terminal, not being instantly vaporized when he engaged with "I" grounded. Just can't see it pulling down battery enough to release solenoid....something somewhere should have produced smoke. In less than a minute in either of our hands, we would know what solenoid he has...or had...but he may never know. Especially now! I just stepped into this affair to prevent archives from recording that 311006 was not same as ST-542. :roll:
 
I too think the lil contact should have burned or welded.. like you say. not being there and seeing what he is using as jump cables and or meter readings. I agree hard to say, other than it's not behaving right.

TEX the solenoid's are still available from Ford at a reasonable price... I have had my share of new aftermarket solenoids bad right out of the box :cry: Mostly sticking... It has to have something to do with the copper content/recipe the off shores use...
