Here's Another Part that ERA Should Sell to Us
|
Better patent that before ERA starts producing them. Who knows, the profits may be enough for Ellie to build her own cobra :LOL:

Patrick,
The problem with a mount like that is that over time, the solid copper will break due to vibration and chassis flex. Could be one season, could be three, it's not a matter of if, but a matter of when.

OK Patrick - your electrical flunky here. I'm not sure I follow the point of this. :confused: My old Corvette doesn't have a neg battery terminal to frame ground and they are notorious for having to ground everything due to the fiberglass body. I don't even have a drivetrain to frame ground on my ERA (but I ordered one from McMasters and intend to install it at the transmission) - and I haven't noticed any issues with grounding. I assume this is just precautionary or have you noticed a problem?

Ya I agree, nice job but I think a #4awg MTW might last longer in our car's with the vibrations. |

By the time that guy vibrates apart, I will long be dead and buried.:LOL:

No problems, just tweaking. But if you want to know whether your frame is properly grounded, turn on your lights and fans and put an inductive ammeter around the little black wire that runs from the passenger side cylinder head to the firewall. If it's carrying more than 15 amps, do some additional grounding. |

You absolutely want a ground from battery to frame and engine to frame!!!! I welded three transmission shift cables before I figured out what was going on when I forgot to reconnect the ground from the engine to frame. You probably are getting your ground through your motor mounts, if you werent the car would not be running.

I also run a braided strap from the intake manifold to the firewall. But in order to get that "little black wire" (which was originally the only ground source to the frame other than nuts/bolts/cables) down to under 15 amps with all of my fans and lights on, I needed a third ground. That little black wire appears to be 14 gauge.

Patrick,
It's your car, you do with it what you want, but you'll be alive when it happens unless you do not plan to be around in the next 1-3 years. The real question is, will you be man enough to admit it when it happens?
Bill S.
PS: There is a reason why regular ground straps are made of stranded or braided materials, same goes for your battery cables. Think about it for a while, you'll figure it all out I'm sure of it. :rolleyes: |

Oh, I don't know. Maybe a check of your prior 15,384 posts might give you a clue.:LOL: |

Which one did you have in mind?:D |

Pat,
I would go with the stranded wire in this case which has some flex. Solid copper would also tend to vibrate more over time since it does not flex. However, I would use solid for very short runs.

Oh by the way, that engine is way to clean. I could eat off of that. You must have solved all your oil leaks! (:

I just ran a braided ground wire from the starter base to the transmission ground. It fit perfect. I cannot imaging anything that is not grounded now!
Patrick - If you are thinking of going the way of all men in the earth early perhaps you could donate your can to Dan or me. I think we could use all of the spare parts.

I have no plans at the present....:cool: |

FYI
If you do not have a good ground between the engine and the chassis and chassis to the battery the electrical current will create its own ground path, this is not a good for your mechanical components! The current will travel through whatever means possible to get back to the battery and completing the circuit. The current can travel through bearings and races, gears, etc. and cause pitting and ultimately failure in those components.

Yes, I have seen the many ground posts. I have many grounds throughout my vehicle and at the present, have no issues.
