Re: electric cooling fans
Good info. But not sure it will help my problem. which is I am wired that when I turn on my A/C the fans through 2relays turn on, this draws my volts at idle negative, It has nothing to do with engine temp. I know what you are going to say is then this is a problem when the pcm turns on both fans for engine temp. Yes and no. Most of the time the pcm only turns on the first fan and that is enough to cool the engine down and not draw enough amps to make me negative, The second fan when turns on is usually a short duration and I am running down the road at enough rpms to keep me positive. So I think I need smaller amp drawing fans so at idle I am positive,. Down here in Houston I got to run A/c almost always. . Beware I am very poorly educated in electric amps and volts so if this makes no sense I understand.

Either way though, you have some other issue. Here are the fans I am running. These work cherry on my truck. I have A/C, electric fans, Dakota gauges, decent stereo, and a bunch of other electric items and the alternator doesn't drop a bit when the fans kick on. https://www.summitracing.com/parts/der-16927 |
