Hello, all. I have installed several sets of off road lamps (14 55w 12v lamps in total) on my H2 (Same engine set up as a 2001-2006 GM 2500/3500 Silverado/Sierra) , and notice a power draw when I have all of them on at the same time (lights dim etc). It has been recommended to me to install a more powerful alternator to compensate for the new power needs, rather than going with dual battery set up at this time. I believe the factory alternator is a 145amp Delphi. What is the power output at idle (500rpm)? I am looking at replacing it with one of two aftermarket alternators rated at 225amp and 250amp. Which would be better for my application? TIA. https://www.amazon.com/LActrical-OUTPUT-ALTERNATOR-CHEVROLET-WARRANTY/dp/B00C3RDNZC https://m.summitracing.com/parts/pwm-48237/none/images
