<VV> Was Still having electrical problems/ now Importance of good grounds

[jvhroberts at aol.com]

 Don't get me started on Lucas, Prince of Darkness... <G> 

And American cars in the 60s had their fair share of ground faults. How many cars from that era had the mysterious taillights that would go out when you hit the brakes, or flash out of sync with the front lights, and other weirdness, all due to bad grounds? And let's not forget the LM dash ground issue. 

And the less said about the Horrid Red Plastic Thingy, the better... <G>

Amen,
 
Anyone who has had a sixties era European car know this first hand as  
well.  On my Greenbrier just detaching, cleaning up and reattaching ground  
wires at the taillights, headlights and parking lights made a tremendous  
difference in lighting brightness.

Without a doubt, good grounds are a MUST! These grounding  straps are for 
RFI issues, but are stout enough (if they're all there) to  improve the 
electrical ground to the engine. Of course, the main reason the  negative 
battery 
cable goes to the engine is for this reason as well.  

One of the things modern cars do a LOT better is grounding. They  
invariably have a grounding wire from whatever electrical/electronic device to  
a 
good, solid ground. No metal clips, no grounding through the screws into the  
body/frame, etc., an actual, honest to God ground wire! A pretty good example 
 to follow, actually, whenever you work on some part, like taillight 
sockets,  etc., would be to add a grounding pigtail, and not rely on the socket 
clips to  the housing to do the job.

Hello  All,  My '65 Monza sedan is still having an electrical  issue and I  
am checking to see if anyone else has experienced a similar  problem.  
First- 
thanks for the advice so far!  <snip> 3- The  copper  ground straps from 
engine to body were in very poor shape-  have been replaced  and ground is 
now 
ok. <snip>

Jim  (and everyone else),
The three or four little copper straps that ground the  engine shroud to  
the body are for radio noise suppression only. If  you got your car or FC  
without a radio, it didn't come with the  straps... also, if you DID get a  
radio, you also got a capacitor  (a.k.a. condenser) installed on the 
voltage  
regulator and the coil  (or if an EM, on the generator and the coil)... to  
the 
best of my  knowledge, all other grounding was done through the factory  
wiring  harness or at the negative battery cable where it attached to the 
frame   
(on EMs) or the small pigtail on the LM ground cable. 

Someone more  knowledgeable than me needs to correct me if I'm wrong...  
Ned? You  did some schematics... what say   you?
