Power to fuse box question

[FeCobra]

I converted my 2638 car to a 140 amp multi wire alternator with an upgraded voltage regular that replaced the original. I also switched the amp meter for a Smith volt meter. The battery has a fresh charge and well connected. There is no battery switch in line between the battery and solenoid. The problem is no power is getting to the fuse box. There is power to the solenoid but does not make it to the fuse box under the steering wheel side of the dash. The lights, fan, wipers also will not work. Is there a main fuse between the solenoid and fuse box that might have blown during the installation? Any comments on what might cause this would be appreciated.

Thanks for the help,
