I need a better wiring diagram for a 76 280z.
My Haynes diagrams suck. I need a
microscope just to see it. Any better ones out there?

My flasher fuse blows every time I start the car.
I've disconnected everything (I think). Turn signal
switch, flasher relay, hazard relay, hazard switch.
The fuse blows with everything disconnected!
I'm lost and now I can only drive straight...

Pull the fuse block off the passenger side of the car. It's possible something has melted behind and is shorting out that circuit. Those blocks get very very hot and have a tendency to melt. Somewhere on the WWW is a FAQ on how to bridge all the inputs together to make better connections and lower the resistamce. Can anyone help with the URL?

There is a book out there called "How to restore your Datsun Z-Car" or soemthing like that. I have it... It's available in the "Zcar.com Bookstore" (amazon.com i think)... It is a kick as book, that has EXCELLENT diagrams of the entire car down to the washer.

RE: wiring diagram

I scanned the one for my 72 out of hanes and blew it up to 24x36. Very easy to read and still clear. If you dont have a scanner, take it to Kinko's

<b>RE: Fuse blown...Better wiring diagram?</b>

Hmm...I have a factory manual for my '76. Does it happen when you turn the key to ON or to START? That would help me find what your problem might be. I took a hard look over the schematic and there are some strange things mixed into the blinker circuit. First off, the power first goes thru the Hazard Switch, this selects the mode for the blinker bulbs, and also which of the two flasher units gets used. If you have unplugged the hazard switch and had the fuse blow then you have some other weirdness happening. From what I can tell the schematic also shows a connector using the same fuse labeled "TO COOLING FAN MOTOR SUB-HARNESS" note that this is not the same as the environmental fan motor. I believe this was for California versions only, although it doesn't state that. Anyway...here's the weirdness. The power from the same fuse also goes forward to the condenser, voltage regulator, to thru C-13 to Automatic transmission switchs(kickdown and top gear.) If unplugging the hazard switch doesn't help, try a new voltage regulator also, or unplugging C-13 in the engine compartment. If this stirs any new questions feel free to ask.

Thanks for the ideas. The voltage regulator is new.
That's what snapped and caused all my original problems. I think the "ON" position is what triggers
the blowout. I'll investigate further this weekend with
a brand new pile of fuses.
