Technical Electrical issues

Hey all....I drove my car all day two days ago with no issues....cleaned it yesterday. ..wanted to drive it today and when I turn the key nothing happens. Gauges dont move, electric fuel pump doesnt come on....nothing. I am running the original flathead with 6v system.
Thoughts as to where to start?

 

Dead battery or you lost your ground,try cleaning the terminals and get back with us. HRP

 

knocked a wire off.

 

Yup, check and clean battery terminals.

 

Don't you think posting 6 different threads asking the same thing is a little excessive? HRP

 

I just posted on one of his other threads before I saw this one...I guess he figures the shotgun approach works best.

 

Guys I am sorry all of this mess. I was trying to post and thought I was having issues so I tried again. I wasnt trying to step on toes or anything. I appreciate all the help and advice...you guys pointed me in the right direction and it was the voltage regulator. I appreciate everything and sorry to waste your time and space on the forum
