Or....you can buy a brand new starter relay (Solenoid) that came bolted to the fender of an 88 or 89 Crown Vic, Towncar, or Merc Marqee. It will not have the 12v output lug for the brown wire (pink wire bypass at starting) but if you need it you could very easily install a relay to provide that function.

The issue that I'm having currently is random. I think the last time the solenoid stuck, it was after the car had sat about a week and a half. I can then go a while with no issues and then it will stick again and I have to tap it.
I still wonder if the solenoids are crap...
Each time it sticks, I lose all the presets in the radio.
This is what i was asking before, how long does the car sit between starts? Is there something else draining the battery. If the battery is low, it will draw more amps to start the car. The radio does not reset stations because the the solenoid sticks, the radio resets because the battery is low.

I would suggest taking your battery and have it tested. My local Advanced Auto (Previously Car Quest) has a tester that will charge and discharge to check its condition. Depending on condition, they might be able restore most of its capacity. It’s not a quick test, just in case you’re expecting fast.
Extreme heat or cold is tough on a battery. Allowing it to sit discharged reduces battery life as well. Sometimes you can charge at a higher current to get the charging started, but have to reduce to lower current so you don’t create excessive (explosive) gases. Definitely perform charging in a well ventilated area away from explosive liquids and gases.

I was reading that if you don't have full voltage to trigger a solenoid, that it might not clamp down the contact solid enough for a proper electrical connection. If the connection is not solid, it will have a greater resistance and can get hot. This could explain the sticking.

Have you checked your starter to see if something may causing high current draw?
You just replaced battery recently?
What size wire from battery to solenoid?
And from solenoid to starter?
Checked for high resistance on cables?
Any questionable crimps or corrosion on cables?
Are you running headers?
This may help us troubleshoot possible root problems causing solenoid failures.

Dan,
Consider adding to your checklist “make sure the solenoid itself is properly grounded through the mounting ears”.

I just caught this while rereading posts.
Once your solenoid sticks closed and doesn’t drop out, especially if starter keeps going.
It is highly recommended to replace it ...or carry a spare when it fails again.
When it sticks like that, the main contacts that feed the starter are damaged...think of bubble gum welds.
As mentioned earlier, check all of your grounds.
I perform this check by leaving one meter lead on positive at battery and place negative lead where it should be grounded.
You should have full or close to full battery voltage at each connection for ground.
Yeah check that connection too Ron. That is the ground for the solenoid.

I usually start and drive the car once or twice a week. Sometimes it might go two weeks, without starting, but I really try to avoid that.
The solenoid seems to stick at random times. When it happens, it will go something like this... I turn the key and then everything goes dead, total power loss. I then pop the hood and either check the tightness of the positive cable to the battery or tap the solenoid. Immediately the power is comes back on and I can start the car. After this little episode happens, I then need to reset all the saved radio stations, because of the total power loss.

The power for the car comes from the same side of the solenoid as the cable from battery positive.
Assuming a good connection and cable between those 2 points, regardless of whether the solenoid is good or not, if that power connection to the car fails, its gotta be on the ground side.
Butt, ya know what they say bout assume. If tapping the solenoid, really restores the connection, then clean and check the connection of wire to both eyelets on that side of the solenoid.
Do the headlights work when it happens?

I was thinking something similar 50vert.
Sounds like an issue from solenoid to the fuse box.
The main power from solenoid- firewall connector- fuse box.
Try this first:
Connect meter to Cigar circuit to ground...should be full battery voltage.
Move wiring around in engine compartment and see if it changes.
I believe the underhood wiring and/or firewall connection has corrosion or poor connection going to fuse box.
Disconnect battery prior to work on firewall connection.
Just be careful with that connector, it may not come apart easily...worst case break on you.
My 65 with gauges, had a melted feed wire to the fuse box both underhood as well as under dash when I bought it.
I had similar problems.
I also ended up changing out my ignition switch too, due to failure as well.

Dan's idea of the firewall connector is a great place to start.

Thanks guys...
The wiring should all be good. I really went over all this and had it all tested. But... maybe there is an issue?
I would have no idea about the headlights going off. When it happens, I go to crank the engine over and I hear this kind of buzz noise (has to be starter attempting to engage) and then everything is dead.
This does not happen all the time, just very randomly.

Testing for continuity with a ohm meter will not show a high resistance problem. Voltage drop test will.
The buzz you hear is probably from the load burning through what connectivity it does have, to none.
Because everything goes out, the problem is between the battery, and where the power supply cable terminates in the cabin. only 4 connection points on that ... battery positive, solenoid, firewall connector, and the end point in the cabin. Or between the battery negative and ground.
How do you have the grounds setup? Is the engine or body ground points heavily painted?
Shouldn't be able to twist battery connection either.

Hello everyone. My 65/ 289 auto is down getting ready for the Bash and my starter looks to be original, brushes are about 1/4 now and full of copper dust. What one would you recommend from Rock Auto or should I go with the Ebay one. If i want the Ebay one you listed is it just a 30amp relay needed and a extra wire to the starter?
Offline
I'm a low tech kinda guy, butt...I looove the new PMGR late model style starter I installed a couple of months ago. Just an idea.

The ebay link has a diagram for using your existing solenoid. If you wanna use a relay to replace the solenoid, and you mount it in the location the solenoid was, you won't need to lengthen the switch wire.
But, you will need a 12v to the relay, wire out to the solenoid on the starter, and a one piece heavy cable to the starter. and a ground. I'd try to hide it a bit, maybe under the battery tray.
You'll also need to lengthen the power supply to the cabin that was on the old solenoid.
It's probably worth mounting a fuse block under the tray.
Use a relay with a diode across the coil to kill the voltage spike generated by the PMGR.

OK I went with the new PMGR starter from the link you sent me , That's the same place I got my 3G alt for my 65, good people. i will keep the stock soilond for now since all my upgraded wiring come from there. Also bought a new harmonic balancer from R.A. since mine was old and cracky. Should be able to get the car back together by mid Jan if I dont take much more apart.

Ok, thanks for all the information on this.
I will definitely check all my earths and connections first up and if I still have issues, I will look at these other two options suggested.
REMEMBER!!! When posting a question about your Mustang or other Ford on this forum, BE SURE to tell us what it is, what year, engine, etc so we have enough information to go on. |
