'74 wiring diagram ?

[David]

Anybody have a PDF handy ? Must be for a '74.

I've lost my copy. I have one on order but I was hoping to do a little work this weekend. The diagram in the tech section looks to be for a pre-74 and a search of the forum didnt come up with a link to one.

TIA

here you go

i ordered this one from prospero's garage, and as you can see some of the labeling is overwritten, so kinda lame, if you get a better one, pls send me back a pic of it.

Thanks Alan. As soon as mine comes in Ill make a high-res scan and ask Dan to post it in the tech section.

Are you able to see where the fuse (not the relay) is for the low beam headlight circuit ? It's that yellow wire.

1 or 3

def not 2, looks like its either 1 or 3. pop em one at a time and see.

Thanks Alan. The problem is the low beams are intermittent. I don't really know what's broken in the circuit. (Fuse, Relay, Switch, Stalk, Wires). Just trying to cross off things definitively.

Remember the ground for the low beam is the high beam filament.
When high beams go on- fogs and lows go off

Check the stalk first, power comes from ignition switch to headlight switch to stalk to relay. Yellow is always to low beam, white is high beam. Send a PM and I will call you if needed.

I can lend you pages 61-0/48 and 61-0/49 which covers the 74 coupes. Have them enlarged at Kinkos.
