Problems keep coming

Hey guys.

This morning, I was driving to school and I blew a radiator hose. After I fixed that, I drove it over to a friends house and we changed the spark plugs and wires. Driving home from his house, with him following me (it was nighttime) he called me and told me my tail lights weren't working. Also that whenever one turn signal worked, the other also blinked at the same time. Not to mention my license plate lights, well, one was working while the other didn't work unless the right turn signal was on. And for that light, it only blinked. Not stayed a constant.

My brake lights worked most of the time. One time when you hit them, they will both go on. The next time? Only one will go on. The time after that? The other will go off. So on and so forth, not in any particular order.

Also, sometimes when i'm driving and I go to take a turn? Sometimes my steering wheel locks up for a second.

Not to mention my gas mileage sucks. I know it's a 25 year old truck, but jeez. Hopefully changing those spark plugs will help.


I guess it's what I get for buying a $500 truck....

It's a good idea to replace ALL of your belts & hoses if they're all of the same vintage.

A factory wiring diagram will be a BIG help in figuring out your electrical problems, e.g.
Lloyds Auto Liturature available for 1985, Fordtruck, Wiring Diagrams

The license plate lights are fed by a brown wire, the same circuit that powers the front side
marker lamps, parking lights, orange cab roof lights (if installed). If one or more of those is
blinking with the turn signals, I would begin with looking at the wiring harness in the back;
there might be PO-added trailer wiring that's messed up back there. I would also clean all
of the grounds and make sure the bulbs & sockets are good.

Ok, I don't like it when people say they don't know much, You may not know about some things, but I am very sure you know something about something! NOBODY knows nothing, everybody knows something!

Everybody just knows about something different ... Thats the power of sharing knowledge!

Many people think grounds are unimportant ... So you do know something!

Grounds are VERY important!

-Enjoy

Ah but if I say I know nothing and mess it up, I can displace the blame, correct?

Well, no... If you know nothing about something and mess it up, the logical
response is, why did you phuque with it?

To learn something about that which you knew nothing. Of course there is a cost associated with all things learned. Sometimes that cost is whatever a real mechanic charges me

I am now 110% sure it is my Headlight Switch.

I will go and buy that... whenever I can afford it...

(Looks at wallet, which has now been empty for 3 weeks)

Headlight switch would not cause brake light problems or one tag light to work. You would lose all park lights, ft and rear
