Ignition help needed. 1973 Duster
Every port on the relay is good and the solenoid is getting power. I admit I haven't used a meter on it but it turns over when you short the circuit. As for the Coil, I haven't touched it
Your statement is confusing, or at least not telling us what we need. What do you mean "the solenoid is getting power?" Power "where?"
The large solenoid terminal ALWAYS gets battery power. The small terminal gets power from the starter relay when triggered by the key in "start." So I'm "guessing" the small terminal is NOT getting power otherwise you whould not be able to "'short" the whatever you are shorting to crank it
SO LET'S TROUBLESHOOT
First find the starter relay and jumper (screwdriver pliers etc) the two largest bare terminals. Be careful, keep the transmission out of gear. It should crank.
If that happens, next probe the two SMALLEST terminals on the relay. Do not disconnect them, leave everything connected, "backprobe" them, with remaining meter probe (or test light) grounded.
One terminal should go down the firewall to transmission (if automatic) or in through a separate firewall grommet into the interior if stick. Probe that terminal, twist the key to start. If you get battery voltage or a light, the neutral safety or clutch switch is NOT grounding so the relay can operate. You can temporarily "try" pulling the wire off and grounding that terminal of the relay If it cranks, concentrate on neutral switch/ shifter adjustment
Another test is to hold the key in start (automatic) and wiggle the shifter from park to neutural and back. If you get a click or try to crank, you have a shifter adjustment or related shift linkage problem
If you do NOT get voltage or a light with key in start, move to the remaining small terminal of the relay. This is often a yellow wire but not always. When key is in "start" that wire/ terminal should be "hot." IF not make CERTAIN!!! That you do NOT have the dreaded '74 only seatbelt interlock. This is a horn-relay sized box with a reset button, normally on the left fender apron.
If you do NOT have that box and the yellow wire is NOT getting power in start, that sources comes from the ignition switch, through the column connector, to and through the bulkhead connector, and out to the relay
IF YOU DO NOT have a service manual you need to get over to MyMopar and download one--free
