93anthracite Posted November 30, 2009 Share Posted November 30, 2009 Background: '73 240z w/ engine removed. Current plan is to thoroughly clean, strip, and re-paint the engine bay and install an L28ET. I may put the L24 back in just to get the car running, haven't quite decided yet... Anyways, I've pulled the engine I'm just trying to identify some specific parts that I couldn't determine what they do. Please see the pictures below and if at all possible let me know what they are and what they do. I REALLY appreciate your help with this. -Dave 1. Located on the passenger side of the engine bay; large multi-wire plug coming off of it. -Voltage Regulator 2. Located on the firewall 3. Located on the firewall - Wiper Relay? 4. Located on the firewall 5. Located on the driver side of the engine bay - fuel vapor return to airbox 6. Located on the driver side of the engine bay - Ballast Resistor Quote Link to comment Share on other sites More sharing options...
Moltar Posted November 30, 2009 Share Posted November 30, 2009 1)Voltage Regulator 6)Ballast Resistor Both of which can be eliminated respectively with the common alternator swap with internal voltage regulator, and 280zx electronic distributor swap. What is with the weld patch over the torsion bar on the passenger side? Quote Link to comment Share on other sites More sharing options...
93anthracite Posted November 30, 2009 Author Share Posted November 30, 2009 Thanks Barbarossa! Good eyes! The weld patch is from putting in Bad Dog sway bar reinforcements. Quote Link to comment Share on other sites More sharing options...

Philly_G35 Posted December 1, 2009 Share Posted December 1, 2009 I believe #3 is the wiper relay. Quote Link to comment Share on other sites More sharing options...

93anthracite Posted December 1, 2009 Author Share Posted December 1, 2009 Thanks Paul, do you have a Haynes manual to reference and provide the answer? So far, I have scoured my Datsun Shop Manual, How to Restore Your Datsun Z-Car, and both books on building and modifying the L-series and none have given the clarification I was hoping for (the voltage regulator was the only one even ID'd in a book so far).

blue72 Posted December 1, 2009 Share Posted December 1, 2009 Was this an A/T car? #1 is in section EE #2, #3, #4 I'd check section AT if it was an auto car, as well as section EC because the '73 cars had more emissions equipment as well. #5 the Flow Guide Valve is in section EC of the FSM on multiple pages. #6 is in section EE I know that most of these are covered in the other books you mentioned as well.

Jehannum Posted December 1, 2009 Share Posted December 1, 2009 5 is a vacuum for the brakes No, 5 is your vapor return - it vents fuel vapor from the tank into the air cleaner box. Quote Link to comment Share on other sites More sharing options...
