Any ideas why I keep blowing the fuse that supports my instrument cluster? Tach, fuel, temp, signals, horn. I've put a 20A in there and it only lasts for a short time. I've cleaned the contacts at the fuse box. Thoughts? Edward Perez Snohomish, WA 78 Midget (1275) http://www.flickr.com/photos/lbc_newbie/
