MAD Bypass Question
Thanks. Credit must go in part to the original creator of the template. I was going to include that info but the IFSJA website where I first posted was down temporarily.
I actually started by using the example rather than blank template. Go down
this page at Jeepforum, Wiring 101 to the bottom of post #3 for the links to the templates. It's actually hosted at a website called Civilian Jeep, but Civilian Jeep doesn't index it. go figure. I used MS Paint which works well with gifs. The mid 80s AMC wiring diagrams are almost impossible to follow; makes one appreciate how clear the Chrysler and even older AMC diagrams were.
To modify it for our Chrysler systems will need to change a bit more. The '85 SJ's used a GM alternator with regulator inside the case. The starter is Ford type with the starter relay directly in the circuit with the starter. In contrast Chrysler starter relays are only in the circuit to the starter solenoid. In that arrangement the heavy plus cable goes directly to the starter.
Jeep SJ Diagram notes:
The dashed red line is a wire with red insulation and white trace. The Alternator is actually grounded to the engine even though I didn't put a ground symbol on it. The switch to ground with an N next to it is the Neutral Safety Switch.
The junction between the Ammeter and B2 also feeds the Headlights and other circuits that don't require a key ON to work (like the Dome light). The ones that do need key 'on' are fed through the ignition switch, but I didn't show that either.
PS. You should be able to download and modify my drawing. If not, let me know and I'll see what permissions I need to change at Flcker
PSS The wires to and from the SJ's Ammeter are 10 gage with a 14 ga fusible link (according to the factory diagram anyway). The highest output alternators from the factory that year was an 85 Amp for fleet, 78 Amp for individuals. In '87 an optional 94 Amp was available.
