So I installed a trans cooler the other day and it works great. It came with a inline t-stat that turns the fan on/off. I noticed that when the fan turns on, my voltmeter goes from 14v to 13v, and when it turns off it goes back to 14v. I do run a 130 amp 3G alt so I figured I'd have more than enough juice to run a simple trans cooler w/o it affecting my voltage so much. Is my voltage drop when the fan turns on to be expected, or am I missing something?
I tried 3 different switched wires off my Centech harness with the same result. I also temporarily jumped it straight to the battery and that did not affect my voltage, it stayed at 14v, but then I figured it was pulling power from the baterry as opposed to the alternator. What am I missing? TIA,
