When I try turning on my Tredex 6.0 the belt runs as fast as possible then shuts down showing a E. Is there an easy way to fix this?

did you check all fuses in dash box and engine by box>?

the first check , is the A/C compression clutch enraged?
that 1st check ,begins the long diagnosis.
if engaged and compr. is spinnng fast (belt not missing)
this mean serious loop failure (Freon)
if not engaged, (bad clutch) that means the BRAIN is blocking it for
good reasons. if true, we can find out easy what it is with a voltmeter.
Its a set of 6 possible logic fails that shut it down.
post back if clutch is disengaged. full time.

Run the software calibration for easy diagnostic and fix it.

God bless you

either drive belt too too big or drive belt tensioner broken or drive belt need adjustment if you have v type belt.

Most likely the valves were bent.
When you attempt to start the motor does it turns over a bit fast and will not sound quit right - Not even attempt to spark up or fire up.
Check engine cylinder compression. The valves were bent when the belt broke.
you will
1. check compression (and when it fails)
2. decide to have the head checked and if possible rebuilt (use new head bolts)
or
3. Look for and buy a low milage used motor
or
4. Look for a rebuilt head

Someone is going to have to look inside, the mechanism that moves the tape has a problem which will cause shutdown, possible belt or mechanical issue.

With cover off and a tape inserted look down at top of cassette and engage in FAST FORWARD----do reels in the cassette move quickly or not-----Sometimes if a worn belt or drive idler running the tape back and forth with fast forward and rewind will cure the issue for a short time----no movement equals no motion and unit should shut down.

1) LUbe the deck belt, the lack of lube produce Shut down, by enough friction between deck vs deck belt
2) Lube the rollers bearing very well
3) Measure the input voltage motor, if there are the motor need repair
4) Measure the output voltage board, for input voltage motor, if there are Not the board is faulty.
5) Run the software calibration, for diagnose, and troubleshooting.
God bless you

You need to replace the motor controller and walking belt.

The noise is caused by the engine running on after the ignition is shut off. It makes noise because the pistons are rattling in the cylinders from incorrect timing. This has nothing to do with the mechanical or electronic timing of the engine. The engine runs on either because of hot glowing carbon deposits in the cylinder head or because the engine was shut down when it was running too fast. Sometimes the carbon can be literally blown out by running the engine at high rpm for a short time. Put it in second gear and run it for a couple of miles on the highway. If this does not work the heads will have to be removed and the carbon cleaned out manually. The shut down when running too fast problem can be caused by the idle being set too high or by shutting the engine off before it has reached idle speed. If you can adjust the idle speed try reducing it. If not always hesitate before shutting the engine down to let it reach idle speed. Good Luck!

DO NOT spray anything into this unit. The problem is a slipping belt and is a simple fix for any audio shop. While possible, it is rare for a motor to fail. There is a small belt that drives the take up side along with a felt clutch assembly that can slip. If this is the case, the unit will realize that the take-up reel is not turning and shutdown the unit. Please have this serviced. The belts will run around $6-$10 total.

Horrible squeal. If my 740 made a horrible squeal I would be upset also. These ideas - timing belt has somehow slipped out of time. Easy check. One of the other belts are slowing the engine any of them can squeal: The alternator belt The power steering belt The fan belt. Does the noise occur only when driving? Does the engine sound normal when revving in neutral? Does turning on the lights or a/c affect the noise? Does the power steering work when car is standing? Is the squeal heard when turning the wheels. A logical diagnosis will identify and eliminate these easy to fix problems.
