Yes you have a internal fault of the amp. the circuit that puts it into safe mode is bad or is seeing something bad and that is a very small chip on the board know as a op amp. needs to be repaired.

Have checked fuses, replaced taillight bulb, checked wireing & ground connections. brake light works but tail light doesnt come on. can anyone help please.


While something has gone wrong to cause the light to stop working, you could spend hours trouble shooting and replacing parts or you can purchase a repair manual from: http://clymer.com/SearchResults.aspx?t=VT1100&y=2005&mid=125&mn=Honda&

The power window will go up and down but smelled like it was burning inside the door then when I put my lights on the tail lights blew out and the fuses i put in it.


The power windows & tail lights or not likely on the
same fuses or circuit

I would address the smell of something burning first
If you have to remove the door panels & look things over

Leave the fuses out for now that blew

You need wiring diagrams after an hour or so
of checking out the tail lights

Fuses only blow from an overload or short,sort of
one in the same

I would be looking for wires rubbing that are in the
circuit that blew the fuse

We can not help at all without having the car,it
may be a time consuming process to find & resolve

If any thing was added to the car that is not factory
or anyone recently did work on it,I would go there first

My amp blew the 20 amp fuses. Replaced and they blew as soon as the radio kicked in. Took the back off to look for any burnt connections or blown open/expanded capacitors or resistors. It smells like...


Remove all the wires from the amp including the remote turn on wire. Once you do that, after about 30 seconds the amp will reset. Hook the power up first, then the ground then the remote. Turn the unit on and check for power WITHOUT the speakers hooked up. If you get no power by now it's a good chance that the amp is cooked. If you do get power, try hoking up your speakers first on one channel then the other channel and then bridged. If it cuts out or off when you touch the speaker wires to one channel or the other, then that channel is no good. Hope this helps.

When i turn on my Samsung HT-C550 IT showing PROT and DVD turn off. What this is mean PROT?


PROT means that the AMP is protecting itself from damage due to bad or incorrect wiring or damaged and or incorrect speakers. Check your wiring and speakers.
If you find no problem then, DISCONNECT YOUR SYSTEM FROM THE POWER, disconnect your speaker wires...all of them, then reconnect the power ONLY, turn on the system and see if it still says PROT. If it does then your amp is damaged.

Hello i just bought a power acoustik cpt1-4000d amplifier and we and a friend of mine were hooking it up and he accidently blew the 4 30 amp fuses in the amp. so we replaced them with 4 40 amp fuses and...


You shouldn't have replaced 30 amp fuses with 40 amp fuses. The 30 amp fuses were in there for a reason. You'll probably find that if you put the correct sized fuses in then it will work. If it doesn't then you have burnt out or melted something and it will need repairing.

Window won't roll down, powersteering doesnt work, spedometer doesnt work, ac doesnt work. all this happend when i charged the vehicle


Hopefully all you blew was some fuses. Need to check all fuses under dash & in relay/fuse box underhood. Easiest way, hook up test light to ground & test across all fuses. If blown 1 side of fuse will get power,but not the other side.

Marathon 2000 amp... PROT light


Ok this means the AMP is in protection mode!..most likely the cause is a short in your wireing from the speaker wires! check all wires going in and out of amp! Look for stray wires touching metal or other contacts! (If this does not fix it the short may be inside of amp!
(This has nothing to do with a fuse!)
Please rate this FREE response!
THANK YOU!

Sounds like you shorted out the main power wire somewhere and killed the amp. Is the amp on the fuse intact or blown? Do you have 12 volts at the amp? check you connections and see if it helps.
