Cowl Induction

Any help out there. When the cowl induction on my 69 camaro gets activated (switch to relay), the fuse for the radio blows and the relay only clicks. No power out to cowl solenoid. Is there something I am missing??

Re: Cowl Induction

Sounds like a short after the relay.

Re: Cowl Induction

Where is the power for the system plugged in? Isn't the main power wire routed inside through the firewall and plugged into the fuse block? Maybe you have it on the same circuit as the radio? May not explain what's wrong w/ the CI system, but maybe why the radio fuse is blowing. As far as the CI, I would say a short in the power line, defective switch, or bad relay. Some guesses to check out...

Re: Cowl Induction

Here's another guess. The fuse blows because the power for the solenoid via the relay is using the radio circuit. You hear the click after the fuse blows because the switch on the throttle arm is still feeding power to the relay. That's my guess and I'm sticking to it.

Re: Cowl Induction

Old thread and I'm wondering if anything has become of it because I am experiencing the same problem..
The aux on the fuse box that powers the cowl flap is fused by the 10Amp radio fuse. Check your schematic UPC12 D2-3..
Once the fuse blows, there is no longer power to the cowl relay or radio (or any other device plugged into the same aux such as power windows).

First fuses blew while my solenoid was stuck on and cooking itself. (What a stench!) I replaced the solenoid with a new one and it's fine but the fuses continue to blow every now and then.. -not consistantly.
The cowl relay appears fine. My multimeter sees no problem with the switched power coming to or from it.. Apart from that, how can it be checked?
What other areas should I look at? Could there be a ground issue between the relay-to-firewall causing this?

Nov 68 Van Nuys. 327 floor-shift-auto, Frost Green and not much else when new.

Re: Cowl Induction

Disconnect the power feeds for the cowl induction from the fuse block and use an ohm meter to check the resistance of the wires both with and without the solenoid switch engaged. It sounds like you are grounding out somewhere. All of the parts for the cowl induction system are pretty cheap to replace.Start with the wiring harness first and then work your way to the switch and relay.There are only so many things that it can be.

Re: Cowl Induction

Sorry, I can not help because I have the same thing happening with my CI. I got tired of trying to find the problem and left it alone. I will be watching this posting. For ideas and help.
