Maybe this goes in Tech, but here goes........
On the race truck - The Bosch alternator has just 2 wires - B+ and D+ (switched 12VDC). The folks at the rebuild shop said to be sure to put a light bulb or 10-15 ohm resistor in the D+ line to drop the D+ voltage to below 12 V - I think the stock value is about 9V. Here are my questions:
1) Would an Ammeter in that line provide more or less the right voltage drop? It will be easy to add that to the dash right now if it'll do the job. I'm thinking a bulb would be ON all the time and that would be distracting.
2) If I'll need the resistor, how many watts?
