[TR] panel lights on TR3

[Carl-TR]

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

Subject: [TR] panel lights on TR3

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.
