Weird dash problem

weirdest thing …(these are the conditions at night headlights on radio on) when I’m at idle my dash lights dim almost out n my radio starts cutting off especially if I hit the brakes or turn signals (basically if I put another load on) my alternators still good n so is the battery any ideas guys

Cmon nobody has an answer

Check your grounds. Better yet just go ahead and replace them. I had very similar issues and my grounds looked okay but were pretty old. Replaced them and cleared up the electrical gremlins I was having.

Ditto the above, kind of.

I would start by just redoing the main grounds, [batt. post and cable clamp, batt. to chassis ground and chassis to engine ground] do not just eyeball the ground connections, undo them, clean both contact surfaces and reconnect making sure the connection is “snug”, do not over-tighten. .

No need to replace the ground cable unless you find something wrong with it. 94

Will do…I’ll keep updates going
