simplest way to wire a Taurus fan?

How can I test the fan to see how many amps are drawn? Thanks frank 30 amp I know is at advance

 

Here's a link for the switches, they're not expensive, and you can get the fuse and holder from any car stereo store!

you can buy a cheap ammeter (dash mounted style) and hook the fan up with a jumper wire to see the initial spike and constant draw. It's not as accurate as the inductive type used with a DVOM, but it will get you in the ball park.

I know many people are using fuses, but on fans, I prefer cycling circuit breakers of the calculated rating you need.

 

I found when I tested my Taurus fan the difference in system voltage between just the battery and having the alternator running made a difference of about 5 amps.

 

Me too...

 

Thanks for the link to the best source I've seen for automotive electrical things. Wish I had known about it sooner I could have saved some $$$$.
