72 240Z Electrical Issues - Please Help

[240Zen]

I finally got my car back from the body shop after19 months...I have some electrical issues which I cannot figure out. After extensive use of the search option, I am stumped. Can someone let me know what the metal relays/flashers? are on the drivers side kick panel? One makes a crackling sound when I connect the positive battery cable (its not connected because there is a power drain). I greatly appreciate any help.

that's a horn relay.

Green/red is power from the fusebox

green/black is contact wire from the horn button

Green wire is directly to the horns.

try looking for a replacement relay (ask around) or find out which one is drawing.

Carlos, change the contact that gets closed from the Green/Red wire to the Green wire, otherwise you'll never get that horn to blow.

Also, when you draw the diagrams, note that the wire color pairs you use should be distinctive as to Primary and Identifier Stripe. As your diagram is drawn they could be read as either Green/Red versus Red/Green or Green/Black versus Black/Green. All 3 wires at the Horn Relay are primarily Green with an identifier stripe, hence Green/Black or Green/Red and not the other way around. In otherwords, make the identifier stripe a smaller band of color to identify it as the stripe.
