I get it to a point and I fundamentally agree with what you are saying, but "negative ground" is pretty standard automotive vernacular even in systems that have dedicated negative runs to everything. Also, the hmmwv (and many modern vehicles) still have a negative "ground" at the engine. The...

In some cases, that's true. In good electrical design, I believe it's best practice to have a single path back to ground where possible. There are multiple reasons for this. Multiple ground paths can create ground loops, which can create electrical problems and interference. It's probably...

Yep, I totally get that now, but why are people buying kits and running a supplemental ground wire from that point to the back of the motor? I see posts about these ground kits being needed because of the hmmwv's aluminum body. Which makes zero sense me, espcially when you say there are not...

Thanks, I was suspect that they were actually ground points (particuarly on the PCB), but I see folks adding a ground to these points with the kits. So where is the breakdown in the ground path that is pushing folks to use these kits (with positive results it seems)? If the motor is well...

I recently went through and cleaned up all my grounds. That spot on the firewall near the heater controls was the only one where I added a supplemental ground back to the engine. It had paint on both sides of the firewall and I did my best to get down to bare metal, it's a tough spot. I'm...
