Dra 355 power button fuse blows out when turned on, does the switch need to be replaced?

That is usually caused by shorted output transistors. What brand/model do you have?

You'll have to get someone to trace the circuits to find the short. You can unplug the master switch in the driver's door and use a circuit breaker in place of the fuse or a fresh fuse.
Toyota door switches have a history of problems. If you disconnect the master switch and the new fuse or circuit breaker does not blow, I would try another switch. You may also have a problem with the wiring harness between the door and the post.
If the new fuse or breaker blows, you will need to disconnect the other motors and switches or look for a short in those circuits.

remove the winker switch on right hand inspect push button spring.if is fine.follow harness to male and female plugs if fine.check the cable from starter solenoid to starter motor if is piled or burnt, run continue test signal for leakage finally test starter motor if is bridging. end of story.

Here are a few things to try to help you diagnois your problem.
1.Check for corrosion on battery terminals and the fuses.

2.Fuses are good - Did you check the fuse on the top of the solenoid?

3. Take a screwdriver and jump the solenoid wires to start the engine. If it starts, then your starter is good. (could be a bad solenoid - but lets check some wires first)
Your solenoid operates when you hit the start button.
Your start button won't work until you turn the on/off switch on.
Your on/off switch only has power when you turn the key on.
4 Use a test light to test the following:
Right Handlebar switch house - Test to see if you have power to on/off switch - Turn your ignition key on & off to see the testlight come on - if light comes on that means your igntion switch is good. If no light, the problem is in the igntion switch. or the main fuse to the igntion switch is bad.

If the light came on then you have power to one side of the on /off switch - test the on /off switch by turning it on and off. When switched to on you should have power to the other side of the on/off switch which is sending power to the rest of the bike which includes your starter button.
Test your start button with the test light by putting the test light on the solenoid - Turn key on - turn on/off switch on - push start button and see if the test light lights up. If the test light lights up that means that your solenoid fuse may be bad. It is located right on the top of the solenoid. If the fuse is good then that means your solenoid is bad. Replace it with a new one.
If the Test light did not come on then your starter button is not making contact and needs fixed or replaced.

So follow the power with the test light until through each component until you come to the faulty one.

NOTE: If its a blown fuse, check your wiring. You'll have to find out why the fuse blew and fix it or your fuse will just blow again. Could be a short somewhere, installing a battery wrong will blow fuses.

Sounds like the power supply went out. Check inside to see if a fuse is blown. Replace it once (with the exact rating) and if it blows a second time, then you have something shorting out and can be costly to repair. DO NOT replace the fuse with a higher rating for it might cause a fire.

Sounds like you have a power supply problem in the amp. I am assuming the fuse you are replacing is intergraterd into the AC connection. You need to dig deeper. If you are not an electronics person you will need a tech.

There is a ground not connected or a wire open that is causing it to blow

If the fuse blows the instant the power is switched on, there is most likely a heavy short in the primary side of the power supply. This could be the rectifier diodes or the switching transistor (or IC). If you do not have experience identifying and replacing shorted semiconductors, allow a qualified tech to handle it for you.

I had the same thing happen. This fixed it...

1. Press master power switch OFF

2. Hold down Speaker A & B buttons simultaneously then press master power switch

Display will flash at 1 second intervals denoting that the microprocessor has reset.

3. Release Speaker A & B buttons

Remote should now work.
