I searched the archives but couldn't find an answer.

Here is how I currently hooked up the wiring:



My problem is I keep cooking the toggle switch (35 amp) The wiring (all 10 gauge) only heats up at the toggle switch, nowhere else. If it is wired up ok now, do I just need to step up to a bigger toggle? or is there another way to do this?

I need to keep it hooked up with a toggle switch because I don't have the money to use one of those fancy thermostatically controlled switches.

BTW - this fan rocks! It keeps my 406 at 180
- pun intended

-OR- Would it be better to wire in this relay instead...



Mfg. P&B
Mfg. # VF4-45F11
1" sq x 1"
SPDT, 12 VDC @ 40 amp
Coil resistance: 90 ohm
With bracket.

It is only $3.25, perhaps this is a better option? Would it be what I need to keep from cooking the switch?

ANY time a wire or switch gets hot, that means it can't handle the current that's flowing through it.

I put a DC Amprobe on my Mark VIII and found it was drawing 38 amps. So a 40 amp relay should theoretically carry the load.

I run two 30-Amp relays in parallel. Some people don't believe in this, but at $1.99 each they,ve served me well for almost two years now. I use a rocker switch to activate the relays.

Just because you're not on the "hot" side of the circuit, doesn't mean that there's no current flow.

Follow my advice and others and use relays to wire the thing.Keep the heavy loads outside of the passenger compartment.

On a side note, I'll post pics of the installation and wiring when I get home and finish the job

Dang it - one other question

Do I need a switch that is always either on or off, OR do I need another type to switch the relay?

What post? Nobody has been in here wacking posts.

You need and off/on switch. Think I have an extra toggle switch that will work the relay. Send me your address.

If yur ordering a relay you should also get the relay connector or base and the wire terminals that are the capture type for the base. 2-50F1001and 2-50F1002are required.

Note: that the line and load connections of the relay are larger than the relay coil connections. The standard crimp on tab terminals will not fit.
