"Does your alternator conversion use a diode in the #1 excite wire to the alternator ? If so then they will draw about 3-7 amps to excite the alternator plus another 4 plus amps for the ignition coil, so 9 amps draw when you tuen on the ignition is about normal. If your alternator conversion uses a resistor or charge indicator light instead of a diode, they will limit the alternator excite current to about 1/2 - 1 amp"
How much am I off ? Like I said, the field circuit when direct wired through a diode will flow 3-7 amps, but only 1/2 - 1 amp with an indicator light inline. Am I really too low at 1/2 amp ? I have never actually put an ammeter on one to measure it. I know that in the 70's, some of the GM veichles had two indicator lights wired in parallel for a little faster alternator excite. They called the second one the "hidden indicator light", as it was hidden in the instrument cluster and did not shine through the GEN or ALT indicator window. This dual bulb setup bumfoosled some mechanics trying to fix a slow to excite alternator. They did not realize that there was another hidden light in there that was burned out and caused the slow alt excite. :-)

Today's Featured Article - Antique Tractor Wiring Basics - by Curtis von Fange. One of the most neglected parts of old tractors is the wiring. After sitting in the elements for half a century or more much equipment wiring has deteriorated to sparsely covered strands of copper or other metal. Plastic insulation has cracked, mice have eaten through the older clothed style coverings and the exposed wires have reacted to winter moisture and salts by turning blue and powdery. Terminal ends have corroded, rusted or just plain evaporated away. Aged wires not only keep an engin
