SD-40 not behaving :(

I think you're going to have to  take the shell off and take a look at the tach reader spacing and condition of the tape., It also sounds like the fly wheel is hitting the shell.

I don't think a feature reset is going to do much.

BTW..... nice track work.

Might be a loose motor too.  That is a sign of no tach reader signal.  Goes to full speed. G

Thank you I'll take a look at it tomorrow, hope its just a loose screw.I'll let you know what I find.

Good morning...........Here are some photos, I don't see anything wrong other than the speaker sounds weak or bad (static).  All screws seem tight, motors are firmly attached, tach stripes look good, sensor looks correct, didn't find any pinched wires. Is there something else I could look for?         Thank you Clem  

Has anyone taken this apart? Is that a screw missing on the swivel pilot or truck side frame?

It appears that the motor may have shifted in the photo? Is it loose? (as G suggested earlier)

I wonder if the amp is failing? I had one go and the engine did act up when it was failing.

Although those are decent pictures, they don't tell if there's any shorts or other loose screws.

 Yeah everything does look  good and tidy.....   

Fly-wheel turn ok by hand?   Feature reset?    You could try pulling all the "plugs ins" except the 2 pin battery, motor leads and the HOT common tack reader ( 5 or is it 7 pin).

Hi Joe that missing screw, is a truck side frame mounting hole, however on this model it has two holes in each tab and that is not used. Sharp eye Joe !

The fly wheels turn real smooth and easy, The motors seem to be firmly in place.

I'll try the feature reset now

Thanks Joe
