Diagnose this Turn Indicator Problem

Mike Rocket J. Squirrel Elliott 12 April 2005 22:57:45
 Okay electrical wizards, here we go with this month's Diagnosis Derby.

71 bus (mine, actually). Turn indicator assembly is a bit loose on the
steering column, so it is possible to rotate it fore and aft a bit.

If it is not exactly in the right location (9 o' clock) a problem can
occur. This happens after using the turn indicator and then switching it
back to the middle position. Instead of just shutting off, like a good
turn indicator should, it goes into "fast blinker" mode. Fiddling with
the turn indicator assembly and rotating it back to 9 o' clock or
thereabouts fixes the problem.

'71 switches the rear lights between turn and stop
functions. If the switch hangs mid-position, it can
still energize the front turns but have no bulb
connected in the rear. Too little current and the
flasher goes into fast mode.

Okay -- what's that got to do with the fact that the system goes into
fast mode when the the turn signal is set to middle (off) position but
the whole turn signal switch assembly is rotated a bit clockwise or
counterclockwise on the steering column. It still switches to middle
position, but the light! the lights! They blink!

Dunno.. Something is dragging mechanically from the
column to the switch mech?
Doesn't the whole switch assy come off by taking 2 screws out?
I'd have a look.

IIRC, the fix for switch that won't stay put is to wrap
the column with elec tape before tightening.
(Not making that up.)

Will do, hope to learn something, will post if I do, hope to add to Body
of Knowledge.

ANYTHING technique that involves wrapping something with electrical tape
has gotta be considered with respect.

....also solves the 'Horn won't shut up' Mode as well.....

There are 2 possibilities:

Only 1 of the lights are blinking, so the current drawn is low, or

The switch is making poor contact thus the extra resistance reduces
the total current drawn.

Either way, the flasher relay is sensitive to the amount of current
drawn, and if that current falls below its threshold the flasher rate
jumps to the fast mode.

 Right.Electrical tape is not the correct technique.Duct tape is!
