Re: Help !!! Solenoid for 47 356 Custom super Clipper
Posted by HH56 On 2013/8/4 17:51:36
Believe your car will have the big 4 terminal AutoLite solenoid. There is a relay inside which may be causing the problem. Here is a troubleshooting guide and schematic from an old Motors Manual which may be of help.
If you have the Delco solenoid, it also has an internal relay. Let us know if you need that information instead.
Not sure what you mean by "can't jump the terminals on the solenoid". Could you be more specific as to which terminals you tried to jump.
If you do have the 4 terminal solenoid, one other thing to look at is the ground connection to the solenoid. If the wiring is done as specified on the senior car, the carb switch supplies voltage to one side of the solenoid. The other side of the solenoid is tied to the ARM terminal on the regulator and solenoid gets ground thru the generator windings.
That circuit was intended as a safety preventing starter operation if the engine was running. It was problematic even when new and Packard issued a bulletin on 20th series to change it back on those cars exhibiting intermittent problems. The lead on regulator from the solenoid was removed and tied directly to ground.
Here is the details of the circuitpackardinfo.com/xoops/html/downloads/SC/SL-VOL16NO12.pdf and there was a followup bulletin. The circuit was applicable on some models until 53 so the same intermittent problems could be present.
