Need help guys finding the grounds for these lights

hey i was wondering when high beams are on is there anything in the lighting system that doesn't get because the high beams are on! Just a lil question before im off to working on my rig i will check back later!!
 
The headlamp circuit is separate from the parking lights. One thing that can be done here is to disconnect the warning buzzer. It looks like that runs off the same parking lamps fuse. It seems to have been a problem for 88 Wagonman above. You have to unplug things to isolate the problem.
 
So let's confirm the situation here. None of the dash lights work? None of the parking lamps work including the license plate light? Headlights only work on high? Parking lamps fuse blows as soon as headlight switch is pulled to first click?
 
ok if dash lights are (instrument cluster) lights than those are not on but to the left of the cluster lights where you see, low washer fluid, brake light, etc those do work because my washer fluid always gives me low washer warning no matter how full (thats another problem for another day) but i know those work because of that on occasion when im driving the low washer light goes out and if i hit a couple of bumps it will come back on (not to get of subject but didnt know if related)
the parking lamps dont work but the hazards do (they share the same parking lamps in front)
license plate (never used it wouldnt know if they worked )
and yes my headlights are stuck in high beams ( i think its because it doesn't feel like the stalk is engaging the rod in the column)
today i disconnected the back lights and left them disconnected put a fuse and pulled the switch fuse blew
 
Okay, you're making progress, you know that it is not the back lights.

Forget all the instrument panel and headlight stuff......until you solve the problem of the blowing fuse, nothing else is important..we'll get to them after we fix the parking lights.

Now....go and unplug the front lights to isolate them.....the plug is in front of the airbox, tied to the radiator support. Undo the plug and see if the fuse blows. post results.

hey sorry i took so long i broke my hhead light socket into 2 seperate plug trying to unplug it... I take it to 2 separate plugs for now

And i found the front light harness connector which was located in between the lights housing on the front drivers side

I unplugged it and I first seen a lot of greenish coating every where on both sides of the connector(male n female)

(note: I the front on 88 its not a 6 pin connector its more than that pretty bulky if you ask me i had to brake the locking taps off just to get it unplug) (cause of the position of the connector)

now what!
 
Okay, did the fuse blow with the connector unplugged? If so, the problem is in the front lights and the first place I would check would be the socket that you replaced?
Now would be a great time to clean out the green corrosion on the connector, use a toothbrush and some lighter fluid or go buy some contact cleaner.
 
I'm confused remind me againwhy that means its in the front lights..... I unplugged them doesn't that mean there no longer connected to the head light switch?
I'm confused

If you unplug them and it doesn't blow a fuse, then the problem is with the front lights. If it still blows the fuse, then the problem is elsewhere.
 
Look at it this way.....if you unplug the rear lights and the fuse still blows you still have a problem. when you unplug the front lights and if the fuse does NOT blow, the front lights are your problem.
remember the old rule, electricity is like water flowing thru a hose. Voltage is the pressure that makes it flow and amperage is the amount of flow. If you cut the hose in half, no water reaches the far end, thats what we are doing, we are cutting the hose in half by unplugging the lights....

Your making it too complicated for him with the water analogy (no offense intended). Think of it like isolating a component, if you turned on the air compressor in your house, and it popped the breaker, you unplug it and reset the breaker then the problem is the compressor right? Same thing, you are isolating possible bad (shorted) components.
 
You want to isolate circuits, not just components. Most likely, the short is in the wiring going to a component. When you unplug the component, you have not eliminated the wiring going to it. It is apparent from the '88 wiring diagram, that you can eliminate whole circuits and separate the front from the rear, right at the headlamp switch. Some other things also run off that fuse that could be blowing the fuse. Start at the source of the current and work your way back instead of starting at the ends and working towards the beginning.
 
how exactly am i suppose to get these 2 wires out of the switch connector again cause its hard my hands are freezing what side of the connector has the lock the side the wires go into or the side that connects to the head light switch

HUH!? Did the fuse blow or not? Are you trying to pull the wires out of the connectors? :twak:
 
ok
i already disconnected the back lights connector and put a fuse it blew with it disconnected
then i disconnected the front parking lights harness connector (in front of the air box)
put in a fuse and pulled the switch fuse blew
So im going with winterbeaters advice trying to disconnect the wires (2 dark blue) going into the headlight switch its in a black connector
how do you pull the wires out he said with a small screw driver but it didn't seem to do anything

I do not recommend pulling the wires from the connectors, but if you do, pull the connector from the switch, insert a small screwdriver into the connector to bend down the tab on the female spade connector, and pull it out.

don't forget that some of these wires are live unless you disconnect the battery first.

Maybe he can learn to weld that way:roflmao::explosion
