The amp rating is to let you know what it CAN produce.. Amperage output is based on the total load of the car. If you only need 90A, the 140A will give you a decent buffer. If you have no extra electrical add-ons, you could save some money by using a smaller unit.. but dont worry about "too much power". --- PRC1216@xxxxxxx wrote: <SNIP > Hervey sells, and the 140 amp seems like it would be > great.
