Mine at an alt. today. I have noticed that the constant on and off cycle with the A/C has been causing a serious current draw on the charging system. Looks like this may need another look see to make this harness better.

I was trying to find out if there was any kind of time-delay relay that could be installed to keep both fans from turning on at the same time. Maybe trun one fan on then the other a couple seconds later, or find something that gradually ramps up the fan speed.

installed the 145 amp today, seems to be a little better on the draw.....
we will see.

I noticed that one ONE fan is on with the A/C turns on if the temp is below where it is set to come on....does that make sense? LOL
