1991 Silverado Electrical Problem
 

Put new battery in yesterday and the old girl fired right up. Started her and drove around; making several stops where I'd have to shut off the engine and restart.

I got home, I came out after supper to start her up and put her in the garage and got nothing. Turned key and heard kind of a "thunk" and now have nothing. I have no power, at all, no lights, no horn; nothing on the "ACC" or "Run" positions.

I'm thinking one of the metal 20 amp fuzes or one of the fuzable links on the firewall. Could it be the ignition swith on the steering column, although that appeared to be in order when I looked at it.

Thanks.
