348 Brake Pump Runs before startup but won't run AFTER startup!

OK took me like 5 minutes to figure out what I'm even looking at. I have a NA car and there is nothing remotely like that. No factory wiring would be like that. I wonder of someone had one of those 355 type grills with different tail lights on there then spliced back the originals before selling.

 

Definitely good to compare, definitely read all kinds of unexpected wonky issues when wiring has been altered on these cars over the years, best of luck!

 

Thinking, I think I recall seeing the owner manual (not WSM) outline the stalk positions and lights, is it possibly in the Canadian manual, I have seen the Canadian owner manual online somewhere.

 

Ooops... my mistake. Corrected diagram:

Maybe try posting on the Canadian forum to see if you get a response? You can use my graphic to make things easier for them to understand.

Yellow/red is also used for low beam headlights

I have no idea what the dual voltage source is for on each light (unless the bulbs are dual element). But why would you need dual element bulbs for parking/marker lights?

 

Some time ago, I bought a 1984 BMW E30 which was an import from Japan to Malaysia. The front amber indicator lamps had dual filament, 5/21W, bulbs and the lamps operated as marker lights at 5W (dim amber) and as flashers (21W), flashing from dim to bright amber.

 

I've seen this same dual function on the Ferrari rear lights. I didn't know it was the same for the front (Canadian) lights.

The 348 front lights seemed to be grouped into

US & Canada
Japan
France
ROW

It seems odd that Ferrari would provide a relay holder for the daytime running light relays, but then require aftermarket wiring to complete the transformation.

And why wasn't the other relay clicking? Are there two relays for left and right daytime running lights or do the relays have different functions?

 

The wiring inside the front lamp shown by Matt is not aftermarket but done in the (lamp) factory. I happen to have a new spare lamp (right, Carello) which I bought on Ebay without checking about the different versions. Now I see that it is actually for the Canadian market.

The reflector (I have removed the ribbed plastic cover from the fog light segment in preparation to convert the lamp to Euro):

I see the inboard lower lamp doesn't have a round bulb. I don't understand how the Euro/ROW and US/Canada can change the function of this lamp.

Do you think the USA diagram has mislabelled the lower lamps?

Do both amber lights (top row) flash during turns on Canadian cars?

 

I would not be surprised (also, the dipped and main beams, C and D, are screwed-up). Anyhow, the two bulbs in the lower section of the lower lamp are identical on Euro - halogen H3 (not H1 as stated in the manuals) so it is easy to swap between fog and flasher, just swap the spade connectors inside the lamp. Looking at the back of the lamp, the two lower bulbs (fog and flasher) can be easily recognised as H3 because they have "pigtails" with male spades whereas H1 bulbs have the male spades directly on them.

As for the US model, I do not know. Does it have two (halogen or other) bulbs in the lower section of the lamp or only one bulb, like the Canadian?

 

Ahh.. I (previously) thought the keyway on the inboard lamp reflector meant a spherical bulb and no interchangeability. Also, I thought the reflector would create a different pattern. Now I have to go back to the drawing board.

I thought the wiring coming into the lamp assembly on the two "factory plugs" might be common on all types, but there is that yellow/red wire coming in on the Canada car.



Why it goes out again to the 3rd plug, I don't know. Could yellow/red be the parking light colour and the wiring going out to the rectangular side marker?
