If you have an amp meter you don't need a light also. The light acts as a resistor and excites the alternator. If it's not the right resistance bulb it will not excite the alternator. A bulb of too little resistance will excite the alternator but will allow the current back to your ignition switch and continue to feed the ignition system after your key is turned off and the engine will continue to run. What we use to do 30 years ago on equipment with amp meters when converting the charging systems from generators to alternators we just put a diode in the place of an idiot lite. This allowed current in to excite the alternator but no back feed to the ignition switch. It worked excellent. The diode can be put any where in that wire. We put them up under the dash where they couldn't be seen. I hope this all makes sense!
