New Engine is in!

[sick_ram]

Well I just finished putting a new engine in my 05 truck after melting #5 and #6. But I have one Question why would my starter be spining backwords? The harness to the starter has only a few cables and they have different plugs so you can't mess them up so I am not sure what is going on. Any Ideas?

Are you sure it's spinning backwards?



Mine acted like it was, but after double checking the connections, I just decided to replace it, and back to new it was.

I thought the same thing. I put another in and still doing it, you can see that the tooth contacts are on the wrong side and its take chuncks of the gears away.

Check polarity (+ -) at starter

Well I took both starters and bench tested them, and the both spunn the wrong way then I switched +/- on the starter and still did it. Do you think they are both bad.

Is there any possibility that your battery could have the polarity reversed?

 

[sick_ram]

I even teseted them with a battery charger and still the same

When both starters spin backwards... They may not be spinning backwards... Hard to get two spinning the wrong way... .



I've seen flywheels and starters destroyed in gassers by a hydrolocked engine, or an engine that kicks back very hard (high timing).



Which way is the motor supposed to turn?



I think the top of the crank spins to the drivers side, which means the starter, if looking straight at it will spin to the left.

Brandon,

Did you make sure your flywheel housings are the same as in no spacer for the starter(that maybe the auto didnt have)?

No doubt, the starters are fine sounds like you have an electronic issue or starter engagement issue.



Remember the engine run clockwise looking at it from the front of the truck.

So the starter will run counter clockwise looking at it standing in front of the truck.



From reading your posts it sounds like you need swap your auto flywheel housing in and remove the manual flywheel housing if they are indeed different.



Like I said one might have a spacer (the spacer is a raised piece of aluminum about . 5") one might not.



Give me a call when you get up!

most starter motors [if not all] have electro magnets. it don't matter which way you feed power to it it will always spin the way it was designed to spin [the armature and field coils are looped in series]

Found the problem had the wrong flywheel houseing. Engine runs greats. Thanks Justin
