Alternator info

Todd,

I learned that lesson the hard way.

We put a 40 amp mini Nippondenso on our car and after 2 runs the starter would barely turn the motor over. We were not charging the battery between runs. So we added the amperage requirements of all the electrical equipment and found that 40 amps was insufficient to power everything and charge the battery.

We bought a 75 amp Powermaster mini alternator from Summit and it has solved our problem. If we have time we put the battery charger on the car, but if we don't we know the battery has plenty of juice to run the car.
