Here is the link for the user manual for your amp if you need it; a poor ground connection can lower the voltage available to the amplifier by essentially adding a resistor in series with the amp. low voltages can often cause overheating in electronic components, but not always and unusual in amplifiers. The poor ground connection itself would get hot, even to the point of fire, and a certain amount of heat is conducted along the wire into the amp terminal, unlikely to be enough to make the amp run hot without you noticing smoldering cable insulation. What exactly do you mean by "not in a good spot"? - a ground connection is only in a bad spot if it is likely to get damaged, or not making a good connection all the way to the battery. - please explain more. A poor ground could lead to low voltage, which could lead to component damage, which could cause the components to run warmer than normal and is probably not reversible, but usually relatively easily repaired. Page 2 of the manual describes the protection function, which should activate if your amp is getting too hot - if it hasnt activated then most likely the temperature you are experiencing is normal. The protection will also cut in if the ground is bad. Hope this helps :)

Just wired up my rear spotlights and wires are heating up what would cause this.

There are two (2) possible problems.
1. What gauge of wires are you using? If the wire gauge is to small it will cause the wires to heat up because the draw of power needed to light the lights is too heavy of a load. You should use 12 gauge or even 10 gauge wires for the lights. It also would not hurt to put an in-line fuse on the hot wire (usually red) so the fuse blows and doesn't cause a fire.

2. You may have a "dead short" where the hot and neutral wires are cross connected which closes the circuit and generates heat. If the wires heat up when the switch is off I would start at the switch and make sure the connections are good and no wires touch any other wires. You may want to check the wires all the way back to see if any insulation is off and the hot wire (red) isn't touching any metal of the vehicle. Remember that vehicles are grounded to the frame so if a positive wire is bare and is touching any metal at all it will short out.

Hope this helps

1991 Toyota Camry cycle. This car runs good sometimes, bad sometimes. every 6 or 7 months the ignition coil will fail. Somthing is causeing it to fail?

Clean every ground wire you can find.

All grounds,battery cables,remove both ends
& clean & every wire you see bolted to the body,
motor or sub frame

Remove & clean mounting to any ignition module
you may have.

Does your plug have the 3rd ground plug on the cord? If yes, does the switch have the paper insulation wrapping around it? Something isn't being grounded correctly.

My rear defrost will not work but the light works, whats the problem

Visually inspect the heating grid attached to the inside of the rear window for breaks in the horizontal lines. Any break in the filaments in the grid will cause a partial failure of the defroster, leaving a portion of the window fogged or obscured.

  • 2 Use a test light or voltmeter to detect breaks in the filaments that aren't visible to the ***** eye. Touch one lead of the light or voltmeter to a grounded metal part of the car and the other lead to a spot on the heating grid. If the light doesn't light or the voltmeter doesn't register a reading, that indicates a break in the filament.
  • 3 Place a piece of tape on each side of the break. Align one piece just above the filament, the other piece just below it, leaving a thin space through which the filament passes.
  • 4 Apply the filament repair liquid with its applicator onto each break you've identified. Be sure to thoroughly cover the broken spot. Allow the repair to fully cure per the instructions on the bottle, then carefully remove the pieces of tape so they don't rip the filament repair.
  • 5 Inspect the the vertical lines on the heating grid if you've discovered that the entire heating grid fails to work. Any break in the vertical lines will cause complete grid failure. These can be can be repaired in the same way as the horizontal lines. Check to ensure that the metal power tabs on each side of the grid are securely fastened to the vertical lines, as a break here will also prevent the entire grid from heating.
  • 6 Reattach the metal power tabs to the heating grid as needed by removing the tab from its connector and repairing it using the epoxy found in the heating tab repair kit. Be sure to allow the full curing time indicated on the kit before reinserting the tab into the connector to ensure that the circuit isn't broken.
  • 7 Check the power switch and wiring to the rear window defogger if there are no breaks in the heating grid and both of the metal power tabs are securely connected to the grid. Replace the switch and/or wiring as necessary.

    you have a grounding problem, and they are hard to find, but first, is your battery in good shape, if not replace it,, after that you have to back track everything , usually its the wire going from the alt back to the battery that has a bad spot in it, any grounding of this wire, and your battery becomes toast. check the battery connections,, also,, check the fuses linked to the alt , , if you have added any amps or lights to the car check for shorts or too much draw on them ,, this causes heat and will fry an alt too

    The main power wire at the battery heats up to the fuse and the fuse heats up but does not blow it is a 30amp glass fuse. what could be the problem, i have been told its a bad ground?or that my positive...

    are you saying the unit wont turn on? if it heats up your ground and power connections are fine as it is completing the circuit. I would deff make sure the ground is as good as can be (sanded off paint and touching raw metal) and if you are using a really small guage wire for your amp that can cause a problem as well. BUT if its not turning on make sure the blue remote wire is correctly connected to both the amp and the head unit.

    My above ground filter is 20 years old. The plug from the motor just last year started to melt and the outlet also has a melted spot. What could be the cause?

    Resistance is the cause. All heated material needs to be replaced. Cut back the wiring until you get to wire that has ZERO heat damage. Splice in at this point. This is a common issue. You just have to cut back until good material, and splice in replacement plug and outlet components.

    I got a ppi d1000/1 amp cant get any sound out of it?

    Make sure your remote wire is hooked up in the right spot, also check your rca plugs and consider replacing them, check all fuses to make sure their not blown, a loose or not good ground wire or power supply wire will also cause this problem. If a power wire has a cut in it, that will also cause fuses to blow, as well as with a ground wire cut, ur amp will not be properly grounded.

    The amplifier will turn on and give out put for limited time then it turns off and the red led comes on. ive rewired it twice now and the grounds are all good

    Your over heating check and see if you can put in cooler spot also make sure u are getting good voltage through wires use a volt meter on pos and neg connectors at amp while radio is down and then when it is 3/4 volume should not drop more than.75 if is then go with bigger wires also if that does not work and amp is hot to touch check on installing fans

    Ground wire has burned plastic cover on my amp

    what type of terminal is on the amp. screw or slip on type?

    The plastic does not carry any type of ground. If your ground wire was melted, that means you have a 'hot' wire shorting across the ground somehow causing a short. This causes excessive heat like an 'arc' welder.

    You might want to check your power wire to make sure its not making any contact to ground. Make sure any foreign debris is not causing a 'bridge' between the 2 posts.

    If your terminals (or place where you hook up power and ground wires) are in good shape, re-wire and turn on the unit.
