Lights - All lights - began blinking when it rained on me

[LtBest]

Hi Everyone,

I thought I was done with electrical fixes and moved on to my new Supertop when after a rain shower passed through my headlights, dash lights, marker lights, and tail lights all began flashing intermittently. After a period of time driving with the flashers on (they worked fine front and back) the flashing light problem went away. (maybe 10 minutes later)

I asked my wife's opinion: Do you think something got wet and after our short drive we A) wind blew the problem dry or B) the engine heat dried the problem away?

She said with a smile:

After replacing the head light switch and the floor dimmer switch I though I had all my electrical problems beat.

This flashing problem - do I look for a bare wire situation or kinks in the wire? I don't understand why a fuse didn't blow if there was an open wire problem.

The last bit of info I can offer is Everything was Dry under the hood and dashboard. The wire that runs to the rear along the driver's side was pretty wet.

Now I know that this is exactly where I should start looking but I'm asking more about what it is I'm looking for exactly.

2 steps forward. . . . 1 step back. The good news is that if I were 'done' with my projects I'd nothing to do!!

Probably a ground wire............. or loose positive + connection that when moisture gets to it doesn't allow complete contact............Just have to look around and shake wires everywhere while the lights are on and see if you can get the lights flashing again or find a loose connection..........Then concentrate on that area.

I finally found it!

Reattaching my new Warn Rock Crawler bumper I saw that I had pinched a wire that led to the not-in-use trailer hitch connections!! Undid the pinch and all lights work fine!

Now if I could just get myself out of the way of my own projects. . . all would be good.

At least they work until the next time it rains.

check the main ground from battery to block and the strap from the top to bottom of the motor mount.

Or until you pinch another wire.

I had the same problem with my tail lights, took forever to find.

this is all the lights, if it is a ground I would have to think it would be a primary one.
