Dash Power Feed Confusion
There is a fusible link in the larger red wire you labelled as "from battery" at the ignition relay.
Thanks. Red or Red with tracer, or green? Chrysler's color designates a wire gage of the link.
The 16ga one you had circled with the blue tag and link runs to the ignition relay aswell but it goes directly to the coloumn connection after the firewall.
Very interesting! It's possible Chrysler Canada seperated the power feed to the key switch from the power feeds that are always hot. We see this on '76 A-bodies.
I was going to use it for a fuel pump but I will re-wire the feed properly from a better source.
Electric fuel pumps can be an issue with the standard wiring strategy and alternator. Even with the very rare option that your car seems to have I'd encourage you to consider using a mechanical pump if you can. If you'er thinking boosted of some sort, keep in mind Studebaker ran a supercharger with a mechanical pump - so it may be possible in your application as well.... Just somehting to think about.
is there a program you are using for these wiring diagrams? Seems like a useful tool
Generally using two very basic programs.
IRFAN shareware. IRFAN has two components. One is "Thumbnails" which allows bulk changes to images, such as resizing, creating resized files with new names and watermarks, etc. The second componenet is Irfanview. It can be opened from a thumbnail or on its own. Images can be marked up and saved in various formats. it also has a screen capture function. There's a small learning curve for Irfanview. A bigger learning curve for bulk operations.
MS Paint. This came with either Windows 7 Pro or maybe I moved a copy over from Win XP. I forget.
Its particularly good for cutting and pasting within a drawing.
For example this is a screenshot of the B-body engine compartment wiring from a pdferized '73 shop manual.
I started by colorizing the circuits of interest. In this case the 60 amp alternator wiring.
Irfanview is good for this beause it has good line size control.
But then to cut away all the unrelated items, and move the items around, Paint is the better program.
Eventually end up with something like this
Notice in this particular version the alternator and voltage regulator wiring is the same as a standard Chrysler.
In contrast the 65 amp alternator, same year, same car lines, is different. It's probably a Leece Neville built alternator.
