OK it would appear that you have a failed "Chopper" transistor(s) in you SMPSU. I would try Googling for the "Service manual" you most probably can buy one online. Good Luck.

1970 volkswagen beetle, my #1 fuse keeps blowing. I am using an 8 amp as suggested, but as soon as i put it in and turn the car on it pops. Any suggestions?


Hey Kellan,
I would try to find out WHY the fuse is blowing.. but... you might try a 10 amp.. BUT NO MORE.... if the 10 amp blows right away... you MUST find out why they are blowing...
Check battery connections, ignition switch, any where the main wiring is passing through the firewall, or anywhere the harness is reduced through tight spaces...

With the fuse blowing like that ,you have a direct short to ground on that circuit. If you don't know how to do automotive electrical circuit testing ,suggest you take to a qualified repair shop.

How to change the fuse on Kitchen Aid model KEMS308SBL02 combination oven and microwave. The oven door locked after a power outage this week and now the oven won't come on.


Hi,

Press the "Off/Clear' button to cancel anything on the display, and reset the microwave. This is a soft reset and will simply get you out of any program you have started. Press it when the cooking complete reminder appears on the display.
Perform a hard reset. Pull the plug out of the wall power supply, and wait a moment. Plug the GE microwave back into the wall power supply to reset any anomalies with the microwave's memory. You will need to reset the time of day if you perform a hard reset.
Reset the time of day. Press the "Clock" button, and turn the dial to set the hours. Press the dial to enter. Follow the same procedure for the minutes and a.m. or p.m. Press the "Start" button to start the clock.

INTERNAL FUSE BLOWN (T500mAL250V) - WHERE CAN I OBTAIN REPLACEMENTS?


It is a T (Trage German for Slow) 500mA 250V fuse.
So you can pop into any electronic parts shop and ask for a "Slow blow 500 Milli Amp 250 volt fuse".
better yet take the old one with, and get be sure to get the same size (physical) one.

Hooked up a two-way radio,now speedometer, rpm, gas gages don't work


I'd check for
(1) blown fuse (owner's manual should list which fuse is for the instrument panel - may list it as IP fuse)
(2) broken wire or loose wire in area where you obtained power for the new accessory.

Where did you get power for the 2-way radio?

If you find a blown fuse, replace, and it immediately blows again, unhook the 2-way radio, replace fuse, and see if that works.

BLOWN FUSES IN THE POWER CORDS ON MY PVS72901


you can get fuses from almost any electrical shop, just take the blown fuse with you, give it to the shopkeeper and ask for a new one. The fuse might be blowing because,
-if you have a fan it might be blocked,
-the DVD Player gets switched on and off,
-The device its connected to might be malfuctioning.

HOPE THIS HELPS!

I think what has happened is that your power supply malfunctioned and what has happened is that a capacitor has blown up. I would suggest that you do a complete search of the power supply to determine the location of the blown capacitor, I would advise getting a schematic to aid you in this. If you don't have experience in electronics I would also advise taking the set to the shop or calling a repairman to take care of this issue.

Try JAYCAR www.jaycar.com.au take the fuse into the store. You should get something to do the job. Be aware that the fuse may have blown for a reason and may be an indication of something more serious.
