Thanks for the reply. I have already redone all the battery and main electrical wiring including grounds, all with marine grade larger gauge cable. I reduced voltage drop from about 1/2 volt to about .05 volts in the main electrical wiring. The stuff in the car is stock so drop gets worse. But the fan is wired to the battery through a relay.

If you have a fan that pulls 30 amps and it runs at idle if the temp is right, you need a spare 30 amps at idle. An alternator does not put out full amperage at idle. I need one that puts out more amps at idle than a 100A unit. Again, I have tried three different 100A units. All work the same. I have tried them all in another 745T as well and they work fine in it (it does not have a lot of extra accessories).
