Question about Profile CL1200 Car Audio Amplifier

Car Amp keeps blowing fuses

My in-line fuse blew so I replaced it. Then after I replaced it my amp played for about two minutes. Then It totally quit. I checked the in-line fuse and it is fine. I then checked the amps fuses are they were blown. I then replaced the amp's fuses and when I went to put the new ones in the immediatly blew. What is going on? Any suggestions?

    What is the audio power IC? Is that the power cable running from the battery to the amp? If so I checked the power from the battery to the in-line fuse holder and its receiving a good charge. Also I checked the power cable from the back of the in-line fuse to the amp and its also receiving a good charge. The amp in the holder is a 60 (forgot the label, ohm or whatever it may be). This happened to me on one of my other amps also.

    Yes, my my amp is rated high. I have a Profile CL1200 amp. I put in new fuses to my amp itself and re hooked it up. When I turned the amp on I noticed smoke coming from out of the top. However, the fuses to the amp, or the fuses to the inline fuses holder were still good. Should I open it or not? Or should I take it to some where to get fixed? About how much do you think it would cost?

The reason why fuses blow is that the current is too much. Is the fuse rating according to the specs ? If yes then ... One or more output power transistor (or audio power IC) may be shorted. have it checked before replacing another fuse as this might cause more damage.

    IC means Intergrated Curcuit. This is a black rectangular shaped componentinside the amplifier that is normally attached to a hetsink to dissipate the heat generated during operation.

    60 amps. This is big. Your amplifier must be rated at 200 watts or more !

    Holy smoke !

    Smoke can come from several components, the worst smoke pruducer are resistors. Capacitors will just pop, and semiconductor will also create smoke.

    Is your amp new?
    Is it possible that you made the wrong connection ? (Positive=red, negative=black). If you connected the wrong polarity, the first to blow is the reverse polarity protection, in many case this is a large diode connected across the supply in reverse polarity. If you are lucky this diode might be the one causing the smoke, it can be easily and cheaply replaced. The cost of th epart will be probably less than $5.

    However because you said that the fuse did not blow, maybe you put a large fuse. This is bad because it might destroyed other parts.

    If you are absolutely positive that your connection is OK, something else might blew up (power MOSFET transistors, power IC, etc.) This can be expensive.

I have a Panasonic inverter microwave. Was working perfectly an hour ago. Now totally dead. There is no light or anything. Have checked plug and fuses. No smell or anything. Can you please help.

Could be a shorted inverter blew fuse and unit dead. Or bad fuse holder got fuse hot and melted fuse so now unit dead. Must check fuse first and if bad replace and try, if it blows as soon as it tries to heat probably bad inverter. If it works for a long while then quits maybe bad fuse holder not grabbing fuse tightly making it over heat. So then bad by temperature not amperage.

Why would my iron heart Lainey 212 combo amp combo be blowing fuses?

Because some component in the amp is failing/failed and drawing too much current. The amp needs a repair shop. Poking around without knowing what you're doing can expose you to leather voltage. Don't do it.

Have a hartke lh1000 head . played about 5 total hours then blew the fuse. is this something i shoud be worried about?

If the fuse is correct ( check manual) it shouldn't blow under normal operation. Once in while a fuse will break internally and thus blow the fuse. look close at the blown fuse If it is a "violent" blow (totally black inside) then you have an overload condition. I would use an ohm meter to check the connection to the speakers. Usually it should be between 8 ohms and 4 ohms if the number is lower than 4 ohms your speakers or wiring are putting to much of a load on the amp. If the fuse was not a "violent" blown fuse then replace with a new fuse of the exact proper value. many amps use an MDL fuse that is a slow blow fuse and has much different in circuit function than a ACG fuse so use only the exact proper furse that the manufacture recomends. If the load (speaker and wiring) is correct and the fuse is correct and still blows then you have a component problem and the amp will need repair

I think i blew my amp. my power and ground wires touched and i lost power to my amp.

Please check the fuse on the car amplifier and line fuse for faulty fuse and have it replaced with the same value or rating.

I installed a Honeywell TH5220d 1029 thermostat on a American Standard AC/Heat pump and the install and setup went fine. It cooles for about and hour and quit. I found the 5 amp fuse at the furnace...

Red wire to R on thermostat red on furnace and red on heat pump Same with white except w1 on thermostat. Blue to common on thermostat common of furnace (probably brown but will be marked) and blue to common on heat pump. yellow to Y on thermostat and straight to heat pump. Orange to O on thermostat and straight to heat pump. If wired correctly with no shorts fuse problem should be solved. commonly people leave enough wire exposed inside the t-stat for wires to short together. This will blow the fuse. Hope this helps. I understand the frustration.

Check engine line stays on

Sometimes the manufacturers code the vehicle's computer to come on to remind owners it is due for servicing. Disconnect the negative battery cable for about 15 minutes. This should reset the computer and cause it to initiate a diagnostic cycle. If the light comes back on, check the fuses. My car blew a 40 amp fuse each time I hit the brakes too hard, causing the light to come on. Although it is not recommended, I changed it to a 50 amp fuse and the light never came on again.

I have a cub cadet 1550, Blew fuse and wont disengage from gear

You have a bad wire which rubbed on the plastic housing to the engine block near the starter mower which causes a short and blows the fuse. I have the same tractor and this happened to mine also. The wire is red.
