How to trigger both CCRM Relays with a single input

[@papajoewil10]

Tons of great technical info as always!

[@MalcolmV8]

Should help some guys out :) I’ve been asked this one many times.

[@jplperformance9073]

Well said sir

Awesome video as always. This Man knows his wiring

[@MalcolmV8]

Glad you liked it.

[@selectyourtools]

Man, your sharp at this stuff! Thanks for your videos!!

[@MalcolmV8]

You're welcome. Hopefully some helpful info.

[@selectyourtools]

@@MalcolmV8 Definitely! I’ve been watching all your cobra videos all day as I have time. Enjoy your content a lot! Great videos man!

[@MalcolmV8]

@@selectyourtools that's great, I have a lot more coming too. Just in the middle of a few bigger projects that take time to finish and then get them rolling again.

@@MalcolmV8 Can’t wait! I will keeping an eye out for them!

awesome info

[@danterakin]

For factory settings, when Hi speed fan circuit is activated, is power still applied to Lo speed fan circuit?

[@MalcolmV8]

Yes. A common trick back in the day would be to set the low & high speed trip points to the exact same temp to have both relays on together.

[@scottadkins918]

you just tying both low and high speed wires together on the electrical fan harness?

[@MalcolmV8]

Yes exactly. That way both outputs are feeding the fan at the same time.

[@scottadkins918]

Not sure if I did something wrong or not but I ran my relay hooked it with the ccrm and when I hook a battery charger to ground and hot it runs? I am using the ford fusion controller also. Is this normal? I havent hooked my signal wire to the holley hp yet.

[@MalcolmV8]

Usually the Ford Fusion fan speed controllers do not turn the fan on unless the signal wire is receiving a PWM signal.

[@scottadkins918]

@@MalcolmV8 I have red power to relay switch, blue low speed to relay ground, high speed green/purple to battery, and ground to relay 87a closed circuit (on). Does this sound right?

[@scottadkins918]

Looks like I had the ground/hot wires backwards. The ford fusion has ground/hot on each side of the controller, and I hooked to the wrong causing power all the time.

[@MalcolmV8]

@@scottadkins918 ah, glad you got it figured out.

[@scottadkins918]

@@MalcolmV8 here is something interesting.. usually the mark 8 fans I have to set it up to 75% power because 100% was shutting down.... pulling too much power I assume
