Frustrating alt whine won't go away...


Guest

Recommended Posts

check out this vid on youtube for this problem

I already have copper wire wrapped around my RCAs outputs and grounded it from my prvious amp...its still there now, and it does not seem to be helping...

Did you used a multimeter on the ground points yet for the amp?

No. For continuity?

nope on impedence on the multimeter negative test lead to the negative post on the battery then a long jumper test lead from the positive on the multimeter to the grounding point where the amp is grounding at for this test

Ok, I'll check the grounds for impedence...since I have rear batt, should I also front battery neg to rear battery neg?

what are the numbers when you check it?

about to go test them...should I disconnect the grounding wire and test it underneath or can I just test from on top of the lug? And i'll let you know.

Tested front battery to ground, I wasn't ohms...I had only sanded it away before...so now that I have a dremel, I used that and ground the surface down, the resistance is now 0 ohms. The noise was actually gone when I started my car up this morning...not sure why or if its permanent...noise is still gone after fixed batt ground

noise is still gone after fixed batt ground

Im not sure if you fixed this or not but it is a grounding issue

ground loop

Not sure if I've permanently fixed it...if it is a ground loop issue, how would you go about trying to fix it?
