SPARKS COMING OUT FROM FRONT SIDE OF HOOD WHILE DRIVING

I am writing to you in connection with my Chevy truck (it is a K10 1986 6,2 L LL4 V8 380 cu. in. 135 HP SCOTTSDALE PICK UP).
I have an electrical problem with it, and I would be happy, if you could help me writing to me a few words.
During driving, a spark pops out sometimes from the front side of the hood, and is seen even during the day. This apparently shows that there is a short circuiting taking place somewhere at the front side of the truck, or under the hood at the front side.
Is it possible for you to give me an insight how to go about it?
In my opinion the most probable cause should be related to either with the horns, the fog lights, or the main electrical toggle switch that exists at the radiator support frame. The truck has two batteries in series. THANK YOU VERY MUCH.
