25 Amp fuses blow, after the unit got wet.

The unit is dry but a continuity check at the fuse socket shows a short circuit.

My 89 VW beetle blows fuses for the cig auxiliary port it requires a 15a fuse but I've tried 20 25 and30 all blew


of course they will blow
you have a dead short in the cigarette lighter socket
at 30 amp it is a wonder that the wires didn't burn up
pull the socket and check where the wire is shorting out

Rear park lights keep blowing fuse


first mistake you make is to increase the fuse capacity to above that required. You have a short in the circuit and by putting such a large fuse in you run the very real risk of burning the wiring loom. Check the bulb sockets and check that the right bulbs are in the sockets. bulbs come in two styles. one has 2 contact points and is either for 2 filaments (stop and tail) or a earth wire (Plastic light units) and the other is a single contact that earths out through the metal base . If you have the wrong bulb in place the current will short directly across the contacts and the light will not come on and the fuse will blow. Fuses for tail lights will be 5 amp maximun

My tail light fuse on my92 s-10 just keeps on blowin and when it blows my tail lights and my inside dash lights doint work, howcome it would b doin that??


Check your tail light and other running light sockets for corrosion.
Pull each and every bulb to check it, also check the back side of the socket.
(Your headlights are not part of this circuit.)
Rust or water with rust will conduct enough current to blow the fuses.
Please revert back to the 20 amp fuse, as you may damage the wires leading to the bulbs in places you won't be able to find or fix.
It's unlikely that it's one of the actual light bulbs, all light bulbs tend to go open instead of shorted, but you can check them too.

My 2000 watts legecy amp is not working whats wrong with it?


HelloPower light doesn't come ON, means there is no power enters inside the circuits. There will be an over current protection fuse, inside the amp, meant to blow up, if any short circuit occur inside the circuit board of the amp, or at outside speaker connection. You should locate this fuse and check it. it will be a glass cartridge type, slided into a fuse holder. You can detach it from its holder by a hard pull out. Just locate it, detach it from the fuse holder, and check it with a multimeter, set in Ohms range. The meter should show continuity. If there is no continuity, means the fuse is blown up. Before replacing the fuse, you have to check the reason for its failure. Without rectifying the reason, if you insert an other fuse and switch ON the set, the inserted new fuse also will blow up. Sometimes, it may cause to further component damage too.So check the circuit for any short. You must have thorough knowledge in electronics and all tools to do the work. If you are not aware in electronics, get this set repaired by any experienced service technician. OK.

Drier stops drying while clothes are still wet.



Hi


If the dryer is not drying the clothes then you would need to check for the following things-

Electric Dryer---

1. Inspect the fuses and circuit breakers they may have burned out or tripped. Usually, dryer will still tumble but not create heat if a fuse or a circuit breaker is not working.

2. Check for the amp reading at 240 V, it should have reading of 24, 21 and 3 amp (approx.) for 2 lines and neutral respectively.

3. Heating element may have turned or the connection to the element might be loose. Sometimes a shorted circuit element will keep on blowing the fuse or circuit breaker.

4. Motor wiring shorting to ground.


Gas Dryer---


1. Inspect the fuses and circuit breakers they may have burned out or tripped. Usually, dryer will still tumble but not create heat if a fuse or a circuit breaker is not working.

2. Check for the continuity of the heating element in your gas dryer using a multimeter. Replace the element if continuity is not there.

3. Inspect the thermal fuse if it is burnt out, it is attached to the exhaust duct on the back panel of the gas dryer. Replace if necessary.

4. Check the igniter by first disconnecting it, and then place the probes onto the two contacts of the igniter. The meter should read under 100 Ohms of resistance, if it is above 100 then replace the igniter.

5. Check the continuity on the flame sensor. The sensors are usually located close by the igniter so are easily visible.

Hope this helps...

The circuit board has a 25 Amp slow blow fuse is blown


if your circuit board has a 25 amp fuse that a lot of power, like running the compressor.. you need to have a model and serial number for the unit , there is no generic control board , each manufacture has it's own design

20 amp fuse for brake lights continually blows out


you have a short in the wiring to your brake circuit.check the pedal switch,it could be cracked and shorting out.those switches are known for having the tail lights stay on until you hit it a few times.the other thing to check is the light assemblies.there may be enough corrosion to cause a short.instead of a fuse,wire a bulb across an open fuse.when the short shows up the bulb will light.use a 25 watt bulb.

Microwave oven blowing 20 amp ceramic fuse


Chances are if the varistor fails, it fails drastically causing a short circuit across the supply. It will sit across the supply (it will look like a thick ceramic capacitor) and you can check for continuity after isolating that at one end. If it shows low resistance (it should show almost open circuit with a Digital meter), replace it.

It need not be the culprit. If you are familiar working with High voltage circuits ( they are lethal inside a microwave ovens as the current capability is high here), you can discharge the doubler capacitor and isolate the high voltage diode to check for shorts in the HT area.
