If I understand what you are saying, then 4.25 volts is getting lost through those cables. Is that right? Almost half the voltage..

When you hooked it up directly to the battery, did you use the same cables?

Hey, it is possible that the battery has a "weak" cell.

You have less voltage through those cables to the starter @ 8.56 volts than a transistor radio battery. It should be 12 volts. I know you said the cables should be good but you have said you are losing 4+ volts between the battery and the starter, so where and why do you think it is going?

As near as I can tell, being you have used 2 different starters, 2 or 3 different batteries, Any only ONE set of jumper cables, and had the same results every time, then I would look at the cables. The car battery should be able to spin that starter for a very long time at a high rate of speed, either starter. With the plug out it should even spin faster and longer, Now here is the catch, IF the 12 volts is making through the cables to the starter.

It is possible for the car battery to have 12 volts and not have enough amps to turn the starter very long. Jumper cables clips, (the things that attach to the posts of the battery), go bad, sometimes in the soldered joint or crimp. Remember only one side of the jumper cable clip has "juice" the other side of the same clip only gets what comes through the pin in the hinge.

Check the battery,the car battery and the jumper cables.Yeah, I know you have already checked them, but that 4+ volts is going somewhere.

The battery even through the jumper cables should be enough to weld with, there should be enough power there to melt steel. The voltage and the amps of that battery from the car should spin the starter and the engine for a long period of time.

Re read my first post on this thread.

 

i took my battery out of the car and hooked it up to the quad and it still does the samething a guy that was working on my well said he thinks it is a spun bearing but he was not positive

 

How did you hook it up to the quad?

Did you use the same jumper cables?
Was it the same battery that you have been using?

Remember when you said it had a voltage drop from the battery to the starter? Did it have it then?

It is like you didn't read my last post. Did you not understand it?

 

i hooked it straight up to the quad in place of the quad battery the battery i used is out of my 04 envoy the battery i was using was out of my 89 mustang

no jumper cables

it still had the voltage drop that is why the guy thought it was a bearing

 

I've really been busy at work so I've been out of the loop for a couple days.

1) So the engine turns with a wrench (proving it is not frozen).

2) Two starters spin outside the engine when jumped directly to a good battery.

3) Two starters don't spin when installed in the engine, and they drag down the voltage on a good car battery (the latter point is the one I'm having the most problem getting my hands around).

If you can spin the engine with a wrench, then so should the starter be able to spin the engine. The starter connects to the engine through a sprag starter clutch. Could the input side (starter side) of the starter clutch be locked up? I can't imagine how this could be, but try spinning the engine again with a wrench (manually with the ignition off), but go backwards this time. This will lock up the starter clutch and spin the engine and starter motor together. It will be tougher than going forward since you will engage the starter motor which will be geared way up when going backwards, but I think it should still spin (I've never tried this).

Spun bearings in the engine would not allow you to turn it with a wrench any easier than the starter motor.

 

on this quad it has a starter chain and when you turn it either way the starter turns
i have pics of it but not sure how to put them on here

 

That is not right. The starter clutch is between the engine and the chain/starter motor. It's function is to disconnect the engine from the starter motor when the quad starts up and runs faster than the starter motor. If the starter is stopped then rotating the engine forward is always faster than a stopped starter so the clutch should disengage and the starter motor should stay still.

When you spin the engine backwards the engine rotation speed is a negative number the starter clutch should lock up and spin the starter.

 

To post pic's (or several other types of documents) on this forum do the following procedure. I'm not sure it is the best or most efficient way, but it works:

1) Find a message you want to reply to with a picture attached (or start a new thread).

2) Above the window where you type in your message look for an icon that looks like a paper clip. Click on it and select "Manage Attachments".

3) A menu pops up that displays the supported file types and the size contraints. If you have a picture (like a *.JPG file) the file could be unnecessarally huge - you may need to use a photo editor to compress the file size down to something that even a dial up account can download.

4) Select "browse" from the ""upload file from my computer" line. Select the file you want to upload and press the "upload" button. If you have several files then upload them all. Note that as you upload files they appear in the "current attachments" box. When you are done uploading files close the window (the red 'X' in the upper right corner if you're running windows).

5) Now you are back in the message edit window. Edit your mesage up to the point where you want to include one of your attachments.

6) Then click on the paper clip icon again. Now you will see the "manage attachments" selection like you did before, but you will also see links to your uploaded attachments as well. Click on the uploaded item you want to insert and the link to your picture (or other supported file) will be inserted into your message.

7) Click the preview button to see the message with picture thumbnails displayed. Click on the thumbnail to see the actual pictures.

8) Close any pictures expanded out from the thumbnails, then Post the message.

 

I wonder what ever happened on this deal.

People should always send something back to let us know what happened.

 

Just re reading and thinking. This engine should have roller bearing on the crank, or needles bearing,if you will, .. Or a babbit rod,(not), but I haven't seen one with inserts, or shells, like an automobile.. Because of that it is hard for me to think it is a "spun" bearing.
