Well I know apparently papajam is the man to ask. Only problem is it looks like he hasn’t been seen around here in over a year. I’m really hoping to track down a color wiring diagram for a 73’ GTV Spica. I don’t know who may have contact info for papajam or maybe who’s taken the mantle from his expertise. But anyone that could help would be greatly appreciated.

Yes, sadly Papajam is in the big racing circuit in the sky speed shifting his GTV with a smile no doubt. I have his ‘73 wiring diagram. It’s different than the ‘74 that was recently posted due to the lack of the seat belt interlock. Just PM me for the file (Papajam had requested these diagrams not be posted on the BB and we continue to respect his request).

So, just to show how incompetent I am. I seem to be struggling with the ignition coil wiring. Rebuilt the distributor and installed new coil. Still no spark despite power into the coil. Clearly I need to quit drinking or I’m just an idiot. Any insight?


73 GTV, I’ve got a green/black wire straight from ignition to +

green wire straight from - to distributor.

what am I missing? There’s a green and yellow wire that comes out of the same harness as the ignition wire but no diagram I can find has a green/yellow wire on it for a 73 Spica GTV. There’s also an orange wire coming off the spica pump to what appears to be a barometric sensor or thermometer of sorts mounted in the bay

You’re missing a wire to the diode. It allows current to flow in only one direction (from the cold start solenoid to the positive terminal on your coil) when the starter is engaged.

The coil won‘t discharge when the starter is engaged without completing this circuit. There should be a red 16ga wire from the starter solenoid to the diode landing on the connector (towards the flat side of the triangle diode symbol where the male connectors are located). The other terminal (on the pointed side of the symbol) is connected to the positive terminal of your coil.

Actually, I’m doing that for him. Here’s a photo of his car.
I'm new to the site and owning an Alfa Romeo, just purchased a 1986 spider, running pretty good but has some electrical issues.
I see Papajam was a big part of this site and sorry for his passing. Sounds like he had a real passion for the cars.
Is anyone continuing his legacy of the electrical diagrams?

Larry, welcome to the world of Alfa. Being located stateside you can generally get the diagram you need from centerlinealfa pretty quickly. If not, I believe classic Alfa still sells some as well. There is some individuals on the forum that will share papajams work in DM but it's generally frowned upon to share his work too publicly or for profit. At least from my experience. Good luck and again, welcome to the cult. Uh, I mean club...
