Few electrical questions here.
I've been using the Taurus fan for a while now but have only wired and been using the low setting, but the low setting isn't strong enough to keep the engine cool at all times. I want to wire in the high setting but it draws a lot of amps. The low setting draws 33amps continuous and the high draws 40amps. The problem is the high can spike to 130amps on startup.

Using a Fluke digital clamp ammeter, we tested the starting (or inrush) current draw and the operating current draw. The Taurus fan pulled a little over 130 amps on startup (only for milliseconds) and settled down to right around 40 amps using the high-speed wire. This is why you must upgrade to the bigger alternator and a Bosch high-powered relay.
They upgraded to a 130amp alternator and used a 75amp relay.
I'm using a 30amp fuse and relay on the low setting...and want to use a 40amp fuse and a relay for the high. I just don't want the relays/amps to blow out when it spikes. Is there a way I can make it gradually draw the amps without the spiking? Also can anyone recommend some good fuses and relays? I'd need 1 fuse and relay to handle 30 amps continuously and 1 fuse and 1 relay to handle 40amps continuously. The fan is being controlled by a Greddy MSS that can signal 2 relays at a specific temp. Another thing is, what guage wire should I be using?
I hope I wont need to upgrade my alternator, 'cause I'm short on cash and don't want to go through the hassle of installing one...or modifying the 110amp Nissan Quest one. I have a base model S14, I think that's rated at 80amps? Seems like overkill to have to upgrade since the high setting settles down to 40amps. But I'm probally wrong in my thinking?
So how should I go about this? Thanks in advance.
