1971 365 gtb4 Daytona ignition system

Do you have a OE copy or reprint of a "365 GTB/4 Chassis Service Manual Abstract" N. 46/71 ?
If not, might be worth obtaining.
While it, like all other Ferrari produced instruction manuals for 365 GTB/4, contains fair amount of inaccuracies/misinformation, it will likely be quite useful for your endeavor.

I have copies of 4 different OEM wiring diagrams for 365 GTB/4 and none are anywhere close to accurate and/or complete, but I've also made 2 (so far) of my own and while they may not be 100% applicable for every car, they are far closer than any the factory produced.

 

Where are you located? Reason I ask is your best resource would be a well restored or good original car. What we call "An iron blueprint".

As Timo has so accurately pointed out factory documents can send you down a rabbit hole.

I might have a decent diagram. I'll look tomorrow.

As I recall the blue ignition boxes are the small ones in the later cars?

yes the blue boxes are the small dinoplexes.
i have an extra chassis service manual available that i will sell.

 

Reprints are readily available, probably from most parts suppliers and not very expensive.
I would highly recommend obtain one if you plan to work on the car.

 

Welcome to the world of 365 GTB/4 (& other vintage production Ferraris).

 

Have you opened the boxes to determine if the stock Marelli components are still inside? In the last 30 or so years it has been SOP to use the original box to contain modern replacements.

 

... or inconspicuously by-passing them altogether.

 

or just set the dinoplexes to emergenza which bypasses the boxes.

 

It wasn't a bad idea to have them but they were not very reliable. I think gutting them and installing aftermarket in the original box was a great idea and based on how many are out there so did a lot of other people.

Now if we could just have all the old boxes back that we threw away in the old days.

A restorer friend is doing an F2 car right now and thats what he is doing.

 

Considering the really low quality of current Marelli points I'd do everything possible to make old production points last.
They have turned into such garbage I try real hard not to work on cars of that period.

 

I hear you.
I work on mainly 50+ y.o. vintage cars and not just Ferraris, so I’m constantly having to deal with less than adequate quality service and other parts made today.
OTOH, I’ve always had a policy not to buy/use anything cheap and more so, nothing made in C***a (and not just automotive), unless absolutely nothing else is available or the item is intended for temporary/throw away use.
I’ve never had or made enough money to afford a luxury of being cheap.
