Problem: Front and rear lights are working although turn-signals
and stop lights does not.
The brake lights and dome light are
on the same circuit- If neither works, this may indicate a problem with the
fuse. Check (them) first. The "lower" fuse on the panel
is for the brakes.. the "upper" fuse is for the directional
signals. While you are "poking" around there- unplug the flasher
unit- and clean the terminals. Then test all the bulbs in the circuit.
The parking lights do not work
either.
The headlights and (front) park
lights are on different circuits- the front "park" lights only
come on when the dash switch is in the down position (no headlights). This
position is seldom used, so internal corrosion is likely. I usually can
jiggle and play with the switch to work the corrosion off... Try that with
someone out front looking for the park lights to flash or come on. If they
do, but won't stay on, you may need to disassemble the headlight switch to
clean it- as that is where the problem is
When I pull the turn-signal
lever up or down nothing at all happens. Should the directional lights the
instrument panel flash like a modern car?
Yes, the indicators in the dash flash
when the turn signals are in use. You should be able to hear the flasher
unit clicking. If one of the indicator lights comes on (and
stays on)- AND you hear the flasher "clicks"- but the indicator
bulb doesn't flash- That usually indicates a burnt-out turn signal bulb on
that side.
And how would I do with the
stop lights?
As stated before- check the fuse and
the bulbs first. Then proceed to
the Brake Light Switch. It is located on the frame- to the left of the
engine (drivers side), below the starter solenoid, in front of the steering
box..just behind the upper control arm..get the idea? It's a round sender
with 2 "posts" sticking up from it. Unplug the 2 wires from it (
it doesn't matter which goes where). One is RED, the other is RED with a
WHITE tracer. The RED one should be "hot". Use a test light to
verify you have power... ..or you can use a jumper wire to bypass the brake
light switch. If the brake lights work, the switch is either bad or the
terminals/connectors are corroded.
This is the point that the Turn
Signals get complicated. When you are STOPPED with your foot on the brakes
(both brake lights on).. and turn on the turn signals- The corresponding
BRAKE light bulb must be bypassed- so that the filament will flash. This is
where the 2 circuits are dependant on each other. The RED/Wt tracer wire
from the brake light switch- goes into the main harness up to the Turn
Signal Switch (TSS). The TSS.. breaks the circuit to that brake light- when
the Directional Signals are used. IF the TSS is corroded (common) or burnt
out (not so common)... the directional signals will not work. You need to
check for power at the TSS Connector (about 1" square black junction
block)- where it comes out of the steering column and into the Main Wiring
Harness. Here's what to look for:
- ***Turn ignition switch to the Accessory
position***
Check for power to the TSS at the BLACK Wire going TO the connector
from the main harness The lead should be "hot"
- Place the lever in the Left Turn
position, and check for power on the
TAN wire and the White w/TAN Tracer wire going TO the connector FROM
the TSS. Both should be "hot".
- Place the lever in the Right Turn
position, and check for power on the
GREEN wire and White w/GREEN Tracer wire going TO the connector FROM
the TSS. Both should be "hot".
It's important that these wires be
returned to their original positions... So try to do them 1 at a time. It
is also wise to use some small needle-nosed pliers to unplug
the wires from the junction block. Usually a small twist will release them.
Somewhere you will find something
amiss... hopefully it's just corrosion , fuses, or bulbs. Long-distance
electrical troubleshooting is difficult! <BG>
