Odd electrical problems

[racprops]

OK Here is an odd one to me. My parking lights, puddle and dash light all go on and stay one as long as the battery is hooked up.

Also my horns don’t work and even the alarm going off does not sound them, I can tell the alarm is going off because I can hear its relay clicking and the parking lights dim in time to the relay.

The odd thing is they worked and were sounding off with the alarm when I first got the truck…now no horns at all.

What is happening??

Check the voltage of your charging system, the battery terminals for corrosion, and the ground wiring.

"Check the voltage of your charging system," A) 13 to 14 Volts "the battery terminals for corrosion", Clean.

"and the ground wiring" That I have no answer for, any suggestion which grounds??

I think it is a modual gone crazy, perhaps the alarm or the lighting control as the parking lights, puddle lights, and interior lights and cluster are all ON.

Thanks for replying.

Check the negative battery cable for corrosion under the area where it's bolted to the body.
