mrazandrewm Posted May 24, 2015 Report Share Posted May 24, 2015 Hey guys. I was changing my ground to a new/better location and now my amplifier will not turn on. No power led or protect led is lit when vehicle is on. I have the REM jumped to the power to check to see if it would work. That is not the case however. I checked the voltage before and after the fuse. Both sides show 14.5v. However, when I check the voltage at the amplifier, it only reads 2.4v. That's not normal is it? When I remove the power wire from the amp the voltage shows 14.5v while vehicle is running. However, when I check the voltage at the amplifier (power wire plugged in), it only reads 2.4v. That's not normal is it? Is my amp fried? *Side note* All three 40 amp fuses are not blown on the amp either. Thanks.

775Tundra Posted May 25, 2015 Report Share Posted May 25, 2015 Anyone??? Check your ground. Take pics and post them of your new ground.

SLYentist Posted May 25, 2015 Report Share Posted May 25, 2015 are you sure your ground is actually a ground? Quote Cables and wires almost never fail; the terminations do. Link to comment Share on other sites More sharing options...
mrazandrewm Posted May 25, 2015 Author Report Share Posted May 25, 2015 Yes. I checked with a mutimeter. I get 0.2 to 0.3 ohms with the new ground. The ground is connected to a bolt that holds down the seat on the front. Will post pics when I get home.

kandiman71874 Posted May 25, 2015 Report Share Posted May 25, 2015 seat belt grounds are generally a terrible place to ground to due to the dirtiness and rust build up those connections can have. Checking resistance with a volt/ohm meter is all find and dandy but that ohm load would be the same if only one strand of wire was touching a ground point. Only way to fully check that the ground is good is to test it's continuity loaded. I would rather use a self tapping screw and star washer on bare cleaned metal than go to a seat belt bolt.

mrazandrewm Posted May 25, 2015 Author Report Share Posted May 25, 2015 It's not a seat belt bolt. It's a bolt that holds the seat to the cab of the truck. But Thanks for the tip.

Broke_Audio_Addict Posted May 25, 2015 Report Share Posted May 25, 2015 (edited) It's not a seat belt bolt. It's a bolt that holds the seat to the cab of the truck. But Thanks for the tip.Still the same thing applies.If you have a truck why aren't you grounding it to the frame?

SLYentist Posted May 25, 2015 Report Share Posted May 25, 2015 those are also not good because they're usually covered in loctite from the factory. loctite is a good electrical insulator. did you check the resistance between the amp ground and the battery low post with everything hooked up?

SIDE SHOW Posted May 26, 2015 Report Share Posted May 26, 2015 check all your fuses and terminal/battery connections are tight and secure... connect the ground back to the original spot and see if it works, if it does then you no the issues is the new ground spot Quote Link to comment Share on other sites More sharing options...
