What'd I do wrong?

Last night after being stopped for one headlight I decided it's time to clean the terminals on the 1987 ex mod 110.
After successful clean and light inspection put fuel panel back into place. .....no headlights, no electricity to them nothing.

Any ideas?
Thanks

Check to make sure you have power across both sides of the fuses for the lights. Are the markers out, or just the headlights? I ran into this same exact scenario...had an issue on one side, took everything apart and cleaned/dielectric greased all the terminals - and it made it worse! Ended up being the shoddy bullet connectors, was able to push them back in tighter and fixed the issue - but I ultimately ended up cutting and putting in spade connectors (but probably should have just moved to WeatherPaks).

In particular check the bullet connector grounds.

No electricity to fuse at all, went to inspect hazard switch n that total came apart but turn signal works when headlights are off but not when headlights are switched to the on position.

No electricity to fuse panel except heater, turn signal and one other .

FWIW, if I run a jumper from the battery to the turn signal post the light do come on.

Too hard to say remotely. Check everything you touched. Not sure what kind of fuse panel you have, but make sure the wires coming into the back of the fuse panel are making good contact.

Is there moisture behind the fuse blocks or mud that could be shorting the blocks out? My '87 110 had a short causing battery drain due to the fuse blocks shorting from oil/grease. A good spray down with carb cleaner (disconnect battery!) and blow dry with compressed air fixed it.

Thanks for reply, have looked at that too.
It still has glass fuses.
Is it at all related to the hazard switch being broke?

Pulled all relays behind fuse panel, the turn signal buzzes but works.

Mine had glass fuses too. I wouldn't think the hazard switch being broken would cause this problem, I'd just disconnect it. There must be a break in the wires to the fuse block from the battery in the main harness if you don't have power to the fuse block. Do you have a wiring diagram? I have one but it's for the 12v trucks.

Hazard won't affect the headlights, only the signals. FWIW I had an issue with mine on the ROW 130, so replaced with a Carling switch - problem solved. I'm working on a switch panel to replace the ROW panel that will accept 3 Carlings in lieu of the factory switches (the original switches are pricey to replace).

If it's buzzing, that can be indicative of a bad ground. Check/wiggle all the connections, I've seen water get in the turn signal relay and wreak havoc as well so check that (it's literally behind the fuse panel).

Is there a different fuse block location other than the one on the interior bulkhead?

The hazard switch must be connected and not broken or the turn signals can not work.

No. Print out a wiring schematic. It is very simple.

The hazard switch has no effect on the headlights start on the bottom of the page and trace the dip beam path through the fuses then the light switch.

Thanks for chiming in.
Where else can I look?
When a wire is jumped from the battery to the terminals for the headlights they will come on, both high/low.
Where/what in the line of electricity can I look?
Or is/has the switch gone bad due to getting better contact through the fuses?

I know it's late, thank you everyone, going back out to look for a ground behind fuse panel, check ignition as top cover is off steering.

Any other ideas be helpful.
Tomorrow I'll call Trevor for a dip/signal switch, hazard, and relay.

Gonna cost $$$ but I am out of ideas.

You should have a separate headlight switch from the high beam. I would pull the plastic cover off the steering column and make sure you are sending power to the fuse box. The key switch might have a loose wire or could be bad. You should have a brown wire going to the fuse box and then a green white or white green, or white wire going into the fuse box. The white wires will get power from the key switch and the brown should be constant power from the battery.

Thanks,have pulled cover off, then pulled switch harness apart, then with jumper wire from battery positive touched all connections and the did work, totally bypassing the dip/hi, low switch.

Leaving me to think the stalk/switch has gone bad though where down line would power be coming from to see if the problem is further back?

------ Follow up post added December 14th, 2014 08:00 PM ------

I cleaned those fuse crimps really good with a .223 brush attached to a drill.
Could the added new connection burn the stalk/switch out?

Headlight Repair with Walm-mart or Autoparts store items

Here is what i would do and have done top get out of a jam...I used this repair in Baja many years ago.......


Run new wires...and new switch along with relay.

Run a new power lead for both new headlights to a relay then wire to battery.

Run a Ground wire for both headlights.

set up new switch in cabin that is plastic show it shows you if power is on or off.

when I saw that you mentioned it is your DD, been there done that...it's what I have done and would do...this way you know you have all new wire and a new relay and new grounds....and you should be good to, it's like wiring in Driving lights but it's your Headlights

This is simple and will work and worked for me...and will allow you to trouble shoot the stock orig system when you have more time.....
