For Paw Randy Please read the info on MAD alt site and PA performance on there site. Yes some alt don't putout alot of amps at idle or 1,000 rpms. Some one wire systems need a min of 2,000 rpms before they start to charge the car after startup. IMO this is bad for both the electric system and the motor. Cold
oil that is thick having to turn higher rpms than should be needed for a cold start. This is why you need a high cca battery. To be honest, 14.7 is high voltage for any system unless you are running a 16.0 volt system, then you are low. This sounds like a weak cell battery in your car. You need to have the battery tested for CCA and load. Most Alt deliver max output by 1,500 rpms. This is nothing new. The voltage regulator controls the output anyway. I run a 70 amp alt with all the same things you are running without any problems. For high ampage systems you should switch over to a voltage gauge. You need to find out what the ampage rate is first. Pulleys on the motor to water pump should be 1-1. pulley ratio should be about 3-1 on the alt to the other pulleys. Rick L.
