anyone do E-fans on a obs??

[ezdaar]

if your melting shit STOP NOW~ and install RELAYS to keep that heavy current off those small wires and fuses!

You can and will if not done right, melt then burn down your vehical!

STOP AND RELAY this stuff NOW!

Well these are not small wires 10 gauge wire like what's used on the fan
And relay. It's just the mini 30 fuse couldn't handle the current.
But I will do a high amp relay to get power from the battery.

I went through 3 of those years ago before I figured out what was up. The deal is that you are pulling too many amps through the relay......not to many amps for the relay to handle, but it gets the whole unit too hot. The potting material starts to melt and it looks like it is kinda leaking oil.

The remedy is to run the wires that you would hook up to the fan(s) and instead hook it up to another relay....this way you move the heat off of the controller itself.

Trust me on this one, I know 100% for sure.

I had the fan wires from the unit go to 2 40 amp relays , so each fan had its own remote relay. You just wire the original controller fan wires to the relay trigger, then battery to the switched part and other pin to fan. Then run the other fan wire to ground. I hope you can understand what I am saying.

Ok u guys win... U guys gotta diagram I could use..?

You need a bigger main relay for the Taurus/Mark VII fans. I ran the Bosch part # from this article on my Taurus fan for a year or more with no issues. You already have the same temp controller so it's not a whole lot of rewiring to do. The relay is expensive but worth it, adding the diode they have listed isn't a bad idea either.

The biggest reason I switched mine out for the dual GXP/Northstar fans was the amount of juice the Taurus fan pulled when it kicked on. That and I got tired of the amount of noise it made

So wat temp sensors are you guys using..? Or how are you guys activating the power to the fans..?

 

[Monstar_est87]

Hummmm... I feel like I cant beat this dead horse anymore...

 

[SunlitComet]

Of course you can.

this is what I used for my two sensors:

i had them make me a custom one with x2 bungs

this is the relay kit, i personally found it to be of better quality then Ray's

scroll down to the bottom and you will see the options...i was amazed at the quality, completeness and directions with the kit...but its $$$

you need speed 1 to turn off when speed 2 activates otherwise you will eventually burn out the motor...i think running it your way would have both speeds on.

To "power" the fans, you are going to need relays. Check out the setup above I used, it identifies the temp sensors and relays.

THis is the expensive way to run both speeds, but it's completely automatic. The cheaper way to run both speeds is with a Volvo relay. I would have gone this route, but I couldn't figure out how to wire the damn thing up.

If you just want to run ONE speed, it's MUCH cheaper. You can get a one speed kit from Jegs/Summit that auto triggers the fan and comes with a nice temp sensor you screw into an existing temp sensor location on your engine block. As a side note, my high speed NEVER kicked it in this summer, low speed on my Lincoln fan cooled it off just fine.

Or you can get that pipe (slice out a small section of your upper radiator hose) I referenced above and mount the temp sensor in there.

This is the pipe with x2 sensors:




This is the relay setup (mounted to the Volant air box)
