need help/ not charging..I think

changed out the ammeter.....used my borrowed (POS) meter...and got meter reading 0f 12volts....depending how you hold it.....if it was mine ...it would be in the trash.....in pieces...

I will buy one tomorrow....for accurate readings

I did deduce that I have power to both pins on the voltage regulator....and it appears there is no voltage drop thru the firewall bulkhaed...I checked that at the steering column connector on the column side

when running at mild rpm...maybe 1500rpm...the guage keeps on the negative side and never goes to the positive side...even with a major rpm increase.....I'm assuming it is NOT charging

also the borrowed NFG meter never increases in voltage over the "key on" /not running reading

whats next?
