Juki 1541S Inconsistent Tension

Any chance of showing the thread path from the spool of thread to the bobbin tension discs onto the bobbin winder.

I am assuming you mean the caution light is for your motor as most of the Juki dnu-1541 don't have a caution light unless you have a DNU-1541-7 with the box of electronics mounted on top of the machine. Since you have oiled and cleaned the machine I would go back to basic's to narrow the problem down.

1) what size of needle are you using for what size of thread?

2) thread path from the thread spool to the needle is it correct?

3) thread caught inside the bobbin case holder?

4) With the machine threaded up and some material under the presser feet

i) remove the drive belt from the machine to the motor

ii) turning the handwheel towards yourself does the machine sew

I would say your problem lies with the motor so check that the motors power cord. Is it in good condition and fully plugged in to a good wall receptacle? The connection from the motor to the on/off switch or the control box in good condition? Also most motor arrangements have a built in fuse which may not be fully seated or faulty.

A couple of photo's of your thread path and motor setup could be helpful.
