charging system problem
have 3 wire alternator. checked the diagram and wired it like this:
main wire - to battery of course
pigtail, twisted and soldered both wires together, put a 4.7ohm resistor in series (same as the cluster bulb needed to charge), then put it to accessory power.
i rebuilt my own alternator and tried 2 others, cannot charge at idle only if it races at least to 2000 rpm will it charge.
i have march perf serp. belt setup on there for electric water pump, pulley sizes all match correctly.
physically it seems like it is spinning too slowly but cant be cure, rpm is near 850 pretty much where i want it but no chargeing at idle or off idle until 2000 rpm is reached?
anyone??
