Electrical Woes (Update)

[willhawk at shaw.ca (W.Hawker)]

Thanks for the advise so far in solving the electrical problems.  The 
problem with the turn signal/tail light  persist. Long hours bent over 
the Bentley and those "#?#@&**&!" wiring diagrams, have only made me 
more aware of the wiring, but no solution. For the uninitiated, here is 
the problem. Left turn signal bulb and the tail light go on together 
when the lights are turned on, plus the signals are all screwed up 
(fronts flash out of sequence on 4-way, or flash quicker on the left)

I pulled the plug from terminal F on the fuse box and checked the 
continuity. The (bk/w) wire from the plug at F19 to the turn signal 
bulb is OK, Same with the taillight circuit from plug F9 to the tail 
light bulb (gr/bk wire).

If I put a volt,meter on the fuse terminal pin F9 (power to the left 
rear tail light)  and operate the light switch everything works as 
expected. Switch ON power to the bulb. Switch OFF, no voltage.

When I connect the voltmeter to pin F19 (power to left rear turn 
signal), and turn on the light switch, current flows through here also. 
  Nothing in the 82 wiring diagram shows how current can go through the 
light switch and into the left turn signal circuit! They are two 
independent circuits. The light switch should not affect the turn 
signal circuit. It is receiving power from the light circuit somewhere.

IDEAS AND SUGGESTIONS WELCOME.

Sorry for the long winded post, but it is hard to describe in less than 
5,000 words.

PS.......The horn now only grunts or a short noise, then stops. Even 
when the contact on the wheel is grounded, only makes an attempt to 
sound.
