can I use this fan controller to run both fans?

I'd like to wire both fans in parallel, and possibly hook up the slim fans in the garage. What happens to amperage in a parallel circuit again?

Why not just run them in parallel with the factory wiring? I had my first Miata set up that way with no issues. What is the amp draw on your fans you want to run?

the stock fans pull 9 amps...so int eh parallel circuit that means 18-amps, right? My stock fans won't turn on, and never will.

oh, ok then, what happened to them?

they stopped working.

What engine management are u using?

I'd recommend using a relay, just because relays are a good idea.

this is irrelevant, I just asked a simple question.

Not really, you can wire both fans in parallel and let MS control them, if thats what you have.

ms is not switching pin 1r to GND for fan activation. Something fried and I'm not paying $700 for another mspnp.

If you can post good pics of the board someone might be able to help diagnose it- a couple bucks of parts and some soldering might get it fixed.

Ahh, now I got ya..

Yes, that will work. You will really want to buy the 3/8 NPT screw in themosister thingy that reads temp. The ones that push-in the radiator are a joke. Besides, the prices is the same. But you'll have to tap something on the motor 3/8NPT and install the fitting.

I've put these on a few different cars. They work REALLY WELL actually. 2000-2001 Jeeps are very prone to electric fan failures because of the utterly rediculous design Chrysler blessed them with. So you can expect a "fan module" (100 bucks) or fans motor (220 bucks) to die ever 10k miles. After 3 fan motors and a new module, I put a new fan and one of these on there. Been working well. And like it says, it even has a wire to hook to the A/C compressor so the fans come on for A/C. (if you have A/C)

I say go for it. Just do a decent job yourself when you wire them up and you'll be fine. The wiring on those is weak-sauce though. I would seriously just let that thing turn on a 30A Bosch relay. The way it's designed now it's got a cheap-o 30A relay that has a harness that plugs into it. Relay's fine, but it will have like 16 ga. wire going to it.

Or if your savvy with electrical crap, just pull the two prongs out of the plug that are your power wires. (one's +12V, the other goes to the fans) and use a heavier wire and a new connector, then snap them back into the plug, then it plugs into the relay like normal.

I just want to get this shit finished. If you're frustrated reading it, think about every time I get in the car.

I'm watching this.

I have a very similar problem with MS and was just planning to get a programmable fan controller + twin spals.

Its just about pushed me over the fucking edge...and there's a silver 135 with red leather in the valley next to some carbotech brakes and nt-01's..

I gave up after 4 hours and just wired the main fan to my cruise control switch. Which sucks because I don't have a coolant temp gauge other than the stock dummy gauge. So I'm prob always running too cold or too hot.

I would use one of the fan controls from Delta Current Control if I was unable to control it with my ecu.

I ran one of these in my Lightning and was very happy with it.
