I am now thoroughly flummoxed ...  found two relatively new lamp holders and
re-did all of the wiring - making sure solder and fittings were tight.  Same
thing happens.  When 5 are in the panel or instruments - all is ok.  Plug in
the sixth and it flickers.  Doesn't matter which location.   To make sure I
had a good ground I added a ground line from the center panel to both the
speedo & tach.  (the dash is powder coated).   So - out they all came again.
On the bench, I hooked up jumpers to all - the same thing happens.  Also
tried it bypassing the fuse holder.  Re-checked all of the holders and none
have any broken insulation; the bulbs sit squarely on the connections;
Really getting frustrating....   I put them back in and will leave one tach
lamp out for now.  I need to keep up the forward progress.  

The other issue now is that the starter just whirs.   I took it out sometime
ago and got the bendix working but now it seems to be stuck again.  Any
suggestions so that I don't have to pull that *&^%(*)^ out again.

It seems that if 5 are connected - all is ok.  Plug in the sixth -
regardless of location - they start flickering. 
Followed Michael's suggestion...  found one that had a cracked separator
between +/-.   Without that one in the mix - all is ok.  
Of course, the spare has been re-used many times and the tines on the
backside are completely useless.  I'll go digging for another but at least I
know the problem.

Thanks Michael & Bill for the quick response.

Carl

I am pulling my hair.  (not out - I need all I have)

 

Installed the 6 panel lamps on the '3 yesterday.  

Two circuits -  one with 4 holders/bulbs for speedo/tach, the other with two
holders/bulbs for center panel

Bench tested all six at one time - all ok.

 

Problem - one holder/lamp in the center panel pair - when installed causes
everything to flicker.  I unplug the offending holder/lamp and no flicker.
I connect a ground and it is back.

 

Switched out for an older holder/lamp - same thing.

Switched the lamps around - same thing. Same location.

 

Not sure it matters but It is the center panel lamp below the turn signal
indicator.

 

Any ideas.

 

Carl
