Should I Fuse an Electric Choke Hot Wire?

[paul67]

I was thinking of an in-line fuse cartridge between the carb and the 12V end of the ballast resistor. Perhaps 15 amp. Is it necessary? Any thoughts on this?

Why?? What would the effect if it shorted.. Absolutely nothing your choke would remain on... I'd be more worried about that wire getting caught on the secondary linkage... Dave.

in my opinion any 12volt hot wire should be fused as close to b+ source as possible or your feed wire could burn up if it shorts out, the fuse size depends on wire size :W Steve

Mine is fused.

What amperage fuse?

Absolutely! Any circuit should be fused. Where'd you pick up power for that choke wire? The ignition circuit off the ballast resistor like the instructions tell you? That circuit is unfused. When the choke wire falls off or gets busted, it'll fall onto the engine - a ground. Not good. I'm very surprised that Holley and Edelbrock don't fuse this wire. Just splice one of those in circuit fuse holder jobbies into the wire up by the beginning of the wire.

I believe your '67 has a fusible link in the ignition circuit. If so, that'll prevent your car and wiring from going up in smoke. But it'll also disable your ignition circuit, so you'll need a tow home.

What amperage fuse?

10 amps.

Thanks! Yes that wire is connected to the bottom, 12V connection on the ballast resistor. And the 1967 does have a fusible link. I'll install a fuse receptacle with a 10A cartridge on that wire.
