No power to the amp i touched the power wire to the side of the amp

I touched my power wire to the side of my amp on accident. Right above the part where the power wire goes i sliped on my tail gate and it touched metal to metaland now i have no power to the amp i checked all fuses but nothing works is there anything i can do to fix that amp my other one still works so i know its the amp

It probably burned a trace on the circuit board.

With the amp hooked up normally and the head unit on (so the amp will have remote voltage), do you read 12v DC anywhere on the case of the amp (black meter probe on the ground terminal of the amp)?

If there is no voltage on the case, confirm that you have 12v on the B+ and remote terminals of the amp (black probe on ground terminal of the amp).

2000 jeep grand cherokee with infinity system right side speakers all stopped working but all speakers on left side still work could it be a amp problem?

If you haven't already checked the balance on your steep do that if its ok then take right hand wires off off amp & concert them to right side if they work it's the amp if not you have a short in wiring on right side of car pull door cards off then make sure no wires are bare or touching together or earthing on body

Power Mirror Wiring Schematic 92 Buick Lesabre 1992 thru 1997 & More

Here is a schematic which my dad & I devised over the course of two hours for the power mirror wiring on our 1992 lesabre, as we couldn't find any wiring info to handle this issue.

That's our/my website, and that folder will let you see & get all of the pictures & diagrams

The wiring harness for the power mirror switch was acquired through Rock Auto, and the wire lettering scheme was embossed onto the plastic.
Here's a written breakout of the wires & their locations/purposes.

A= Ground
B= Common Left/Right Motion(Splits to both sides)
C= Common Up/Down Motion(Splits to both sides)
D= Left Side - Left/Right Motion
E= Left Side - Up/Down Motion
F= Right Side - Up/Down Motion
G= Right Side - Left/Right Motion
H= Positive 12V

Now Assuming that all of the power mirrors are wired & color coordinated the same, that would connect....
B -- Light Blue wire of Both Mirrors
C -- Green wire of Both Mirrors
D -- Gray wire of Drivers Side Mirror
E -- Dark Blue wire of Drivers Side Mirror
F -- Dark Blue wire of Passengers Side Mirror
G -- Gray wire of Passengers Side Mirror

In our circumstance we hooked up the power and ground inline with the power window Power(Pink) & Ground(Black) wires which are nearby in the door. The fuse/circuit should easily handle the minor load of power mirrors, even if you were using the windows and mirrors at the very same time... a rarity I do suppose.

How to Trouble shoot Low Voltage Controls on AC-Heat

What I have always been told is if your 24 volt side burns out check the high volt side if the hi volt side burns out check the low volt side.

A quick way if the primary side is burning out due to a problem with the low volt side:
1* Mark all the thermostat wires at the indoor unit.
2* Disconnect them at the indoor unit.
3 Check main line voltage before proceeding (A on electric furnaces, 208 volt is not considered 220V and 240v Is not considered 208V. In these circumstances the voltage may have changed with the power company replacing a transformer and now you need to change the main power input lines at your control transformer for the correct operating voltage). If OK then proceed:

4 If you have an amp meter attach it to one of the lines going to the transformer.
5 Apply main power and listen for hum, note if smell starts again and if so problem has to be in board or main incoming voltage too high or too low. Amp draw should be less than 3 amps.
6 If your to this point and still haven't found any trouble in the above as of yet, Connect the wire marked "C" together. Then just touch the thermostat wires one at a time to the places where they go on the indoor unit and watch the amp meter. If you don't see the meter jump the circuit is probably OK but leave them disconnected until you touch all of them to the correct place or wire. Here is a possible problem I have seen a thermostat wiring problem if the wires are stripped too far and a "whisker" of the wire sticks out and allows one of the other wires to cross short out. In this case just cut off the excess wire or bend it over out of the way and continue with the test. You can always cut it off later after the tests. If you see the meter jump up and stay up and /or blows the fuse the wire that you used and it blew is where to concentrate.

(* you may need to reattach the wires at the indoor section then disconnect them at the Thermostat and then at the out door unit if you have not discover the cause at this point or after finding the wire(s) that cause the Spike on the AMP meter. Just take your amp meter with you and reconnect the "R" wire first and check it first. after that if nothing shows at each place connect the "R" back and proceed with touching each other wire individually while amp reading the "R" wire).

7 No wiring problem found means that you could have a relay or contactor not pulling in properly.
and this will cause the amp draw to go way over the transformers power out put or VA rating.
8 Inspect the thermostat wiring for the "whisker" I mentioned above.
9 If you have done this to the end of the thermostat wires and your main incoming voltage is correctly wired in on the transformer and your relays and contactors are pulling in evenly and not delaying excessively your problem should be fixed.

If this helps you please rate me as high as you can and thank you for using fix ya.

I replaced the spark plugs & spark plug wires with new & noticed the wire was totally melted on the left side of the engine (if you are standing in front of the car) right next to the exhaust...

Sounds like the wire was touching the exhaust manifold and was melted by the heat. There is usually a plastic thing that you clamp the wires into that keeps them from touching the exhaust manifold.
If theres not one of those things on your car, then use a zip tie or a piece of wire to tie the spark plug wire away from the exhaust manifold onto something above the wire on the cylinder head, throttle cable or something like that.

If it happened the way you described it. I don't see how it could possibly have damaged anything. I guess what you are saying is that the left tail lights are not working? ("4 way exterior dim lights"???) Touching the tail light wire to the turn signal wire will only cause your turn signals to light up. (I am assuming that the tail light switch was on at the time)
I think it is more likely that the brown wire touched ground. This would make a bright flash, blow a fuse and cause the symptom you are describing...I think you need to check the fuse again.
There are separate fuses for the left and right sides. The left side tail lamp fuse is fuse #7 in the junction block it is a 10 Amp fuse. The junction block is located on the right cowl side inner panel - We are NOT talking about the Power Distribution Center under the hood.

All of the above is also assuming that we are talking about a plain Cherokee, Cherokee SE, Cherokee classic or Cherokee Limited.

If we are talking about any of the Grand Cherokees, you may have a fried lamp outage module.

Hi There. Any impact damage that was able to rip your ampifier loose may possibly have done some damage inside the amp. I would reccomend that you disconnect your amplifier and take it in to a reputable dealer to be bench tested. They will be able to give you the diagnosis.
P. S. If ypou feel that you are technically minded and are able to solder proffesionally, then open your amplifier. Check the board for breaks or hairline cracks under a light. Repair if any are found. Check for broken solder joints on the reverse side of the board. Repair any that you may find. Stripping your amplifir is NOT RECOMENDED and WILL VOID your warranty.

Hope you solve your problem. :)

Ultra linear ul-600hc

If the amp is in protect mode, it probably has shorted output transistors. To eliminate other possible problems, do the following. I'll assume that you've checked the amplifier's on-board fuses.

With your multimeter set to DC volts, the black meter lead on the ground terminal of the amp (not on the point where the ground wire connected to the vehicle) and the head unit on (so the amp will have remote voltage applied), touch the red lead alternately to the B+ and remote terminals of the amp. If the voltage is below ~11 volts, you need to check the wiring feeding whichever line is too low.

If the voltage remains near or above 12v, disconnect all speaker wires from the speaker terminals of the amp and disconnect signal cables from the amp. If it powers up, the wiring needs to be checked. If it still shuts down, the amp almost certainly has shorted output transistors and will need to be repaired.

Let me know if you have any other questions.

Shorted a speaker wire together

Check the fuse. If its not blown rewire the ground to bare metal.  make sure the power wire is the right gauge aand connected right
