The tensioner will always tell you if you need a new belt or not. Q: Will I need a smaller belt for my high amp unit?Ī: This varies by application because not all belts and belt tensioners are in the same condition. Q: Why is the pulley on a high amp alternator smaller than my stock pulley?Ī: The smaller pulley advances the power curve of the alternator just slightly, which produces a little more amperage around the idle if needed. This must be done while the vehicle is running. Q: Where is the best place to get a voltage reading of the alternator output?Ī: You’ll get the most accurate voltage reading from the back of the alternator at the main charge post that runs directly to the battery. In some cases, the charging systems will fall totally on the battery at idle and completely stop charging. Q: Will aftermarket underdrive pulleys (crankshaft power pulley) have any effect on my alternator?Ī: Yes, underdrive crankshaft pulleys slow all the components (power steering, a/c, and alternator) to provide more power to the rear wheels. Higher amperage is not bad and will not hurt a battery, but high voltage will blow one up. No alternator works continuously at full output. A High Output unit works exactly like a factory unit and only produces what is being demanded. Q: Does a High Amp unit cause any damage to my battery or my vehicles charging system?Ī: As long as it is installed properly with battery in good condition, then no. It is IMPARATIVE to have proper charge and ground cables. It’s the same reason firetrucks do not use garden hoses. ![]() Q: Do I need a larger charge wire for a High Output unit?Ī: The high amp unit will operate better than stock, but not to its full potential without a larger charge wire. Yes, you have a full year to make sure your alternator meets your expectations.ġ00% Brand New Aftermarket Part From DB Electrical DB Electrical delivers exceptional value for products that we stand behind with our total-confidence 1-year warranty.
