There is something electrically shorted out. DO NOT TRY TO POWER IT UP UNTIL A TECH CHECKS IT - unless of course you are a fan of whole house barbecue. Unplug it and do not plug it back in - I am begging you for your own safety!

SOURCE: I have a 1999 Yamaha Wolverine. When start button

it sounds to me like you have a faulty terminal, check voltage reading to the relay from battery pos terminal, now push and hold button and recheck on same terminal, if it stays at around 12volts check terminal on other side of relay it this is lower significantly than first side replace again with new relay. of both terminals voltage drops you have faulty battery.

SOURCE: cooling fan runs continuously, trying to locate the relay switch

Should be located in front of left frame rail (pictured below). May have to remove the left headlamp capusel and air intake cover to gain access to relay. You may also try from underneath vehicle before removing these components.

Check fuses. Check voltage. Could be a burned, or just broken fuse. Could be a dead battery. Could be as simple as poor battery connections. If not, perhaps the following will help:

A starter can be tested in a very simple way, by applying 12vdc to the power input, and grounding the case. If it spins, then it's on to step 2, checking connections.

Starters are much too simple to be more complicated than that, but the electrical system can be. Check the circuit between the relay and the starter. Is is a direct wire with no breaks? If so, check the voltage at the power output and input of the relay. If it is good, check the power input and grounding of the starter.

Most new bikes have a clutch switch, and it may interrupt the 12vdc to the starter, without affecting the relay. Same thing goes for the nuetral switch.

Try starting in nuetral, with the clutch pulled. Check the relay for conections that you may have taken off, and not replaced. Same thing for the starter.

Yamaha psr-e333. Can switch on but cannot play even the grandpiano func. Its just "yamaha" written on the display..

To start with try a master reset, whilst the instrument is off press and hold the top (highest) sounding key whilst turning on.
When the screen displays Yamaha release the top key.
If this doesn't solve the issue then it could be a number of things as the keyboard does a self check on startup and will hang if a fault is found. Check each rubber switch is not stuck down or even missing this can cause this issue. Please report back either way.

Here you go:

Scroll down to "Get manual" on the webpage and click to download. IGNORE other download links. This is a class D amplifier and the switching power supplies run directly off the power line so as a qualified technician I am sure you know to use an isolation transformer while working on this for personal safety. I am GOING to make an educated guess at the problem... The circuitry has a surge limiting precharge for the input power filter with a thermistor that when power is almost up and circuits are balanced the thermistor is shorted out by a relay so that the high currents can be handled... I suspect that the thermistor has gone bad... now that can be due to a short in the rectifier filter combination OR even a failure in the switching power supply or lastly, just a part failure of the thermistor. Using an isolation transformer, ALSO put a 100 watt incandescent lamp in serie with the power input cord to act as a resetable fuse and current limiter while working on this. Let me know how it goes...

Likely a connection to the backlight is being broken. Tap on the unoit and see if it pops back on. Illuminate screen with a flashlight and see if the characters can be seen when screen is faded. If they can, then the backlight is the problem... IF NOT then the display may be bad... This has been a problem and if you are under warranty, excersise it immediately... else replacement of the display is relatively expensive.

The speaker connected to my Yamaha EMX 312 SC is not bringing out any sound when we use the microphones but the displays on the power mix shows there is activity.

Assuming that you have checked the speaker leads for broken connections and that you know the speakers themselves work okay (test with a different amp) and that you can hear sound on the headphone socket
  1. Check that you actually have the power amp switch in the right position for the outputs (monitor jacks or main neutrik/speakon sockets) that you are using (see page 25 of the manual)
  2. That your speakers are connected to the speaker outlets on the rear panel and not the 'main outputs' on the front panel, which are for use with a separate power amplifier
  3. Check the mute button is not in
  4. You have turned both the master volume controls up.
If none of the above solves the problem it is likely that the overload protection fuses on the amplifier output stage have blown and need replacing - take to a repairer
You can find the user's manual here

Faded out the sound and will not turn power up

Make sure the STANDBY switch is not pressed. It will fade sound out on the first 8 channels and keep it off.

No sound from Yamaha Electone HS-6

First check if you get sound from the headphone jack.

Do you hear anything as the power comes on from the speakers..? A slight bump?

A lot of these dead audio things can be traced to a failure at the expression pedal. often these use a light dependent resistor and the illuminating lamp burns out. This is all down by the pedal.

Many of the Yamaha organs, including the FX20 I have, have circuitry that checks that the power amp has DC balance before a relay closes to connect the speaker. A failure in the amp can cause dead sound as well.

I have a 2600 peavey amplifier and when i turn the volum up it cuts off for about 2-3 seconds what i need to do

check that the cooling fans are working. if they are not then you are probably triggering the thermal overload protection.
