[DeTomaso] Hazard Warning Switch Issues - Part 2

[SOBill at aol.com]

Chris,
 
The green wire comes from Fuse #8 and provides power to flasher  module when 
the Ignition Switch is OFF........ like you were parked by the side  of the 
road. This allows you to verify 95% of all the wiring.
 
The illumination for the Hazard Switch comes from the instrument  dimmer when 
the headlights are on and will be fairly dim. There will be just  enough 
light so you can find the switch in the dark.
 
When the hazard switch is depressed, the illumination will go to  full 
brightness and will flash and will cycle with the flasher.  If illumination doesn't 
go to full bright, either the flasher is bad or the  hazard switch is bad  
..... assuming all the wires are connected  correctly.
 
With ignition OFF, depress the hazard switch. Pull the flasher unit  and 
jumper 12V to the upper right hand socket. The turn  signals and turn indicator 
should now follow the turn signal switch position  (but not blink) and the 
hazard switch illumination should be at full  brightness.if the turn signals work 
correctly you have checked out a lot of  wiring. If the hazard switch doesn't 
illuminate you have a bad hazard switch.  The switches are available from BMW 
and are also repairable.
 
Check for 12V at the upper left hand socket of the  flasher socket. If you 
have 12V (from Fuse #8), release the hazard switch, put  the ignition switch in 
run, at check for 12V again. If you do not have  12V, the wire from Fuse #12 
is missing from Pin #15 of the hazard  switch.
 
When all of the above checks OK, with the ignition OFF, install the  flasher 
unit and depress the hazard switch, all the lights should flash. If they  do 
not flash, you have a bad flasher unit. Release the hazard switch, put  the 
ignition in Run. Turn signal lights should flash only you use the turn  signal 
switch.
 
let me know what you find.
 
Have fun,
