Review: Solved my low voltage issues - I have a 1970 Oldsmobile with a Holley Sniper, electric fuel pump, dual electric fans, and a high power stereo system by Polk. With everything running, including the A/C, I was under 12Volts at idle or cruise! I kept running my battery down. I tried throwing every SI type alternator I could find at it, more amps more amps and more amps. I was up to 120AMP Si alternator. Nothing was solving the problem of no volts at Idle. This has solved that problem. And this is WHY they came up with the CS series alternators in the 1980s. When you have all those electronics and a low revving alternator, you need volts, not just Amps. The CS alternator puts out Volts at low RPM and I didn't need ALL those amps.
Review: Excellent Installed on 69 Dodge Truck!!! - Upgraded to internal regulator and Higher amp!!! Had to put upside down and make bracket drill some new holes. Did not have to change the original bracket!!! Some Engineering and working perfectly!!! Upgraded all wire to new bigger for the added amps. Thanks!!!
