turns over very slowly when hot

[racerrad8]

Good comments, Randy. But the problem lies with heat. If my bike is cold, it is able to crank repeatedly over and over and over, but usually fires right up. When cold, my starter is very strong. BUT when the bike has been running in the heat... maybe even stop and go traffic in the city or something, if I shut it down, I get an extremely slow crank - maybe just a couple revolutions and that's it. That shouldn't be a ground issue, right?

It could be, heat causes higher resistance which means if the ground side is weak when cold it is even worse when hot.

But, with that said the starter will do the same thing when hot as the resistance within the starter is higher than the battery can overcome.

Just what are you calling a solenoid?  There is a starter relay, but that's not a solenoid.  The FJ starter works through a starter clutch.  It has no solenoid.

David,

This;

Ford has sold billions of these since the 50's; Starter Solenoid:

A solenoid is a wire wrapped in a coil to create a magnetic field thus actuating a rod. A relay has a small version of that inside and a solenoid has a large version. What they control is dependant on the amperage requirement(s) of the application.

The only connection of a solenoid to the Bendix or starter drive is the actuation of the steel shaft to engage it into the flywheel. Yamaha uses the one way clutch ans leaves the starter in constant mesh so there is not need to actuate a lever to engage the starter drive.

These are two totally different functions and no matter who make the starter drive, they all do the same thing; allow the starter to turn the engine over and then freewheel so the engine doesn't continue to turn the starter when running.

P.S. I have sent an email to Ford Motor Company so they can update all of there service and parts manuals to the correct there terminology.

one of the reasons for mine was a main fuse. The starter is still a little slow the first few seconds but then engages fine. I finally had to look what was causing the problem when I got nothing when I turned the key. Not even a headlight and as I checked around showed a blown fuse. It must have been real burnt and just hanging by a thread when I was having the real slow starts.

Got it. That all makes sense. Thank you!

I guess when I said "solonoid" I assumed the FJ had one mounted on the starter (I didn't look or know). I've rebuilt and tinkered with a billion Chevy small-block V8s and I knew my FJ acted just like those do when you run headers near the starter/solonoid. The smokin' hot exhaust that close really cooks them and makes them fail quickly.

P.S. - My fuses are all perfect.

I would like to add that I drove it today and this this is STILL A BEAST. You need to be an experienced/mature rider to push this thing to the redline through the first few gears!!!

Randy, if you're going to be pedantic, I'm going to attack your use of there/their/they're... !

I agree, I'd call it a solenoid.  It's a bigass relay, but common usage calls it a solenoid when it's used in a starter system.  In theory a relay is a coil that snaps a set of connections closed/open, but a solenoid does the same thing in a linear fashion to cause movement.  Call it a linear relay if you want, I suspect?

I call it a solenoid too. The guy at the parts counter knows what I mean.  "It's that little round thingy next to the battery   "

Yes, I know...My dad was an auto mechanics instructor for over 40 years, so sometimes I do have to much knowledge for my own good ;

but...


I must say I was laughing pretty hard when I wrote that 5:23 this morning. As I posted it, I was sitting there in my chair, I got a call from the one & only Amsoil Ed and we chuckled and talked for quite sometime. He was wondering if they're (Ford) considering renaming the solenoid to a relay and I told him I doubted if the really gave a care about what their parts are called...

Then after our conversation I reread my post I saw the error of my way, but do to the inability to edit the post after a specified time period ; my boo-boo is now part if the world wide web history...

Now back to our regularly scheduled antics...

Randy, the bold is the difference between a solenoid and a relay....  A solenoid does mechanical work, such as actuate the arm that throws the bendix into engagement. A relay is an electro-mechanical switch, which is a switch ONLY.  The Ford part is called a solenoid, but it actually is NOT, it is only a relay.

Nope.... it's a starter relay, just like the diagram shows.  David's right, relay yes, solenoid no. Hint: If it switches/controls electrical current, it's a relay.

The "solenoid" shown on the above single line diagram is part of the Calif model's vapor recovery system.

It really depends if you are south of the Mason/Dixon or not.

It really depends if you are south of the Mason/Dixon or not.

I live in south eastern PA.  Although I am clearly a Yankee, the Mason/Dixon is maybe 8 miles from my back door.  I cross it all the time for tax free shopping!  Funny, I don't remember once seeing a sign or anything. Nor do I change what I call my power plant after I've crossed it.

To the point, I call it either an engine or motor depending on mood (not current location).

Sooo much for the guys question...nerds.
