The latest routing (that I know of) is as follows:
Power from the 1 wire alternator gos directly to the AMP meter - then thru the AMP meter - and over to the right side of the fuse...then a wire goes from the same right side of the fuse back into the engine compartment and connects to the hot side of the starter solenoid on the firewall. If you have removed your firewall solenoid, connect to the starter hot side.. This wire routing is the power source "TO" all the cars electrical users and is used to charge the battery. Power can be drawn from the alternator and/or the battery as necessary.
Back to the fuse:
Power can now pass thru the fuses to the left post which is the source for all the power users on the car, switched or unstitched. If something you connect does not draw power from this wiring system, the AMP meter will not see it as a power user and won't react to its load.

Yours really seems to have a screwy routing...Sounds like you have 2 feeds from the alternator/battery. One to the AMP meter and one to the left side of the fuse. Was your car built on a Monday after a 3 day weekend? So yes, If you understand what I wrote, make the necessary modifications if not call.

NOTE: There is an alternate routing where power from the alternator goes to the hot side of the starter solenoid on the firewall first and then a jumper goes to the AMP meter; feeding the cars power users...but note that any users connected to the starter solenoid post (like the MSD box, DRIVING LIGHTS, ETC) will not be sensed by the AMP meter.

I waited for a call from you last night but it stormed here like all hell last night..phones may have been down.
