Why havemy dyson DC 59 has stated to pulse on and off after afew seconds of working?


Hi Dave, it's Jack at Dyson.

DC59's motor will make a rapid pulsing noise to warn you if something is stopping airflow from passing through the machine. The motor will then shut off for protection.

This should be quick and easy to resolve by checking the motorised floor tool, wand and bin inlet for blockages. It's also a good idea to give the washable pre-filter a rinse in cold water if this hasn't been done recently - we recommend washing it at least once a month. Make sure the filter is allowed to dry completely for at least 24 hours before replacing it.

I'm confident this will resolve the issue. If you would like further assistance after giving these steps a try, please call the Dyson Customer Helpline on 0800 298 0298 (UK), 1-866-693-9766 (US), 1-877-397-6622 (CA) or 1800 239 766 (AU).

2001 Acura mdx abs light stays on. Code reads 04?


I think you pulled the code incorrectly, or are reading it wrong. To get code:
1. Jump pins 4 & 9 on OD2 connector.
2. Turn key 2 clicks.
3. ABS light should blink to give you code. (long blinks for first digit, short ones for second. Example: One long blink and three short blinks would be 13).
Honda ABS trouble codes list :
11= Right front wheel sensor (open/short to body ground/short to power)
12= Faulty right front wheel sensor pulse signal
13= Left front wheel sensor (open/short to body ground/short to power)
14= Faulty left front wheel sensor pulse signal
15= Right rear wheel sensor (open/short to body ground/short to power)
16= Faulty right rear wheel sensor pulse signal
17= Left rear wheel sensor (open/short to body ground/short to power)
18= Faulty left rear wheel sensor pulse signal
21= Continous Operation (chipped pulser)
31-38 are all the same: "solenoid"
51= Motor lock
52= Motor stuck off
53= Motor stuck on
54= Main realy stuck off
61= Ignition voltage
81= CPU (central processing unit)

Please clear cmos if system no display after overclocking


Click the following picture to enlarge:
pctech1_0.png

CPU Overheated
If the system shutdown automatically after power on system for seconds, that means the CPU protection function has been activated. When the CPU is over heated, the motherboard will shutdown automatically to avoid a damage of the CPU, and the system may not power on again.

In this case, please double check:
1. The CPU cooler surface is placed evenly with the CPU surface.
2. CPU fan is rotated normally.
3. CPU fan speed is fulfilling with the CPU speed.

After confirmed, please follow steps below to relief the CPU protection function.
1. Remove the power cord from power supply for seconds.
2. Wait for seconds.
3. Plug in the power cord and boot up the system.

Or you can:
1. Clear the CMOS data.
2. Wait for seconds.
3. Power on the system again.

If after clearing the CMOS you still have no display, you may have damaged your motherboard, CPU, or RAM. If you need further assistance with this Motherboard, let me know.

PA9336. The protection LED remains ON. If the power switch is turned ON & OFF rapidly, the protection LED goes OFF & the amplifier functions normally. Please advise. Thanks. A.A.Mulla.


I wouldn't try repeated rapid power cycles if I were you.


Generally speaking, an amp protects itself from heat, shorts and overloads by refusing to turn on or stay on.


Overloads can be from excessive periods of high output or marginally low impedance loading by the speakers; and shorts would be wiring issues or a speaker blowing up.


You should be able to feel if it's hot. WHY is it overheating? Make sure it has sufficient ventilation on all sides and that vent holes are not blocked by dust balls. Ensure the fan (if equipped) is running as designed (some only operate on demand). Clean dust and debris from it.


If the amp comes back on after cooling, you're lucky. They only have so many self-protection cycles in their lives so continuously resetting or cycling their power without addressing the cause can do more harm than good.


If it protects immediately on a cool power up you should disconnect the speaker connections and try it 'naked'. If it comes up then diagnose which lead(s) are shorted. If it does not come up the problem is internal and should be left to an experienced and competent hands-on tech.

I have a JBL GTO 7001, it switches in an out of protection mode. i pulled out the amp, an noticed that the positive wire from the speaker was pulled out. so i disconnected the power scorce an reconnected...


Make sure that your positives and negatives are lined up correctly. This happened to me during my latest install and the problem was I had one positive speaker wire plugged into a negative speaker terminal. This switches the amp on after a few seconds and then back to protect mode once it detects a faulty speaker wire. Hope this helps!

I want a programmable timer that can, eg, switch on a single phase electric motor for 10 seconds every hour. It may be 9 secs or 11 secs.


You need a programmable interval timer.

http://waterheatertimer.org/Intermatic-timers-and-manuals.html#ET70
Intermatic and Tork make digital timers with interval settings that can be set for specific short-duration with 1 minute minimum.
(Or set to pulse bell ringing with 1-127 seconds.
10 minutes is 600 seconds)
For example ET70115 single-channel timer.
The timer would be set for 24-hour operation, and then programmed for Pulse, and then set timer with 24 programs, with 1 program for each hour.

Mechanical cycle timers from Intermatic:
http://waterheatertimer.org/Intermatic-timers-and-manuals.html#cycle
1) Talento 1 hour cycle timer/ each tripper represents 1.25 minutes
2) Model C8835/ each tripper represents 15 seconds.
To operate these timers certain hours of the day, add another timer in-line.
The in-line timer could be digital, but remember digital timers are not protected from power surge and tend to have more problems, and do not have replaceable clock motors and trippers.

Amp cycles on and off


Hello it sounds like the amp is going in & out of protection normally the protect light will pulse at the same time but is not always the case if you can get hold of a voltmeter set it to the 20v range & check to see if there is 12v present between the RCA (Phono socket) input & shield, if so then the switch mode power supply transformer is faulty. It could also be a number of problems elsewhere as well so really needs to be inspected by an experienced engineer.

Clarion apa4320 amp power light pulses


There is not enough power coming from you radio to power the amp. You might want to look in to a capacitor. What this will do is it will pull in the power and maintain a steady output for your amp to operate
