Icon8 Weird Electrical Issue

I recently had my engine swapped. Had a H22A4 before and I had another swapped in. But after the swap I started having weird electronic issues. I've had my battery and my alternator tested and they both are good. When I'm driving and I shift or put the clutch in, or let off the gas or some sort of jerking motion the radio will cut out or my headlights will dim. My temperature gauge also does ready correctly. It'll fluctuate with the bass of my car. And with summer here, I need that gauge to read correctly just in case. I have researched and haven't found anything. Sometimes my idle will die down to like 100rpms and when that happens the lights inside my car and outside will dim with it, and then when it returns to normal, the lights will as well. So I have no idea. Any help, or troubleshooting tips would be awesome. Thanks!

Re: Weird Electrical Issue

How much juice is your stereo pulling?
Could be you have an undr powered alternator.

Pretty much got flamed for driving like a jackass and was told to slow down. And I'll be damned, slowing down fixed it.

Well my I had my stereo in the car before the swap. I'm not exactly sure. I have 1 10" and a 1000w amp. I'll try to upload a video and put the link here so you can get a better visual.

Here's a link to a video of it. It's not too bad in the video, but it'll help you get a visualization.

Re: Weird Electrical Issue

I'd be willing to bet that when you had your swap done some of your wiring in your harness was damaged and/or not properly connected. Sounds to me like there is good chance that you have a short in the wiring. That's probably why when you shift or any other change in motion is also moving whatever damaged/incorrectly connected wiring you have. The fluctuating gauge is strange, but either way something is definitely coming in contact or has somehow been tied in circuit with something else. Grab a flashlight and check out your wiring harnesses. Good luck and let us know what you find.

Re: Weird Electrical Issue

^^ Good points 9998.

Check your grounds.

If you don't have one download a service manual, and note the vast number of grounds your car has. Chapter 23 if memory serves...

The sensor that's supposed to go into the air intake, isn't able to go in because the aftermarket intake that came with it doesn't have a spot for it, so I learned that is why my idle fluctuates. I have a crack in my coil, so I'm changing that tomorrow. The ground from the battery to the frame was super tight so I changed it so it could be more free. Still no fix. Tomorrow I'm going to check the other grounds. If I can't find anything then I'm going to take it to an electrical shop and have them redo it all and clean it all up and if that doesn't solve the issue then shoot me please haha.

Re: Weird Electrical Issue

Well it sounds like you have at least made some headway. Electrical issues are something that can make anyone pull their hair out. Just be consistent with your checks and keep an eye out for any exposed wiring where the insulation has rubbed off or been cut as well as any places where the wiring may actually be trying to pull out of the back of a connector. It doesn't take a whole lot to pull a wire out of a connector or at least make it loose to the point where it makes a poor connection. good luck

Re: Weird Electrical Issue

Well I took a look and a good deal of the engine grounds weren't there. I added one ground and the problem went away.
