Re: Starter Button and General Wiring Questions - 1941 Packard 110

On the starter switch, the schematic shows it being powered from the BAT side of ign switch so active all the time. The engine will crank with the key off but only start with key on because the coil is fed off it's own terminal and only active when ign sw is on.

Don't know if that was a Packard exclusive or if other cars of the era also cranked at any time. Packard did change that on 42s when they went with the carb switch. Looking at the schematic, if the wire is long enough it would appear yours could be changed by moving the wire feeding starter switch from the bat side to the switched side of ign switch.

The headlight circuit looks to be the same as later models so front parking lights would have nothing to do with the CB cycling if disconnected unless one of the wires is shorted. The front parking lights should go off when switch is in position headlights are on leaving only the headlights and tail lights. If CB cycles only in that position I would suspect a short or problem in headlight or tail light wiring.

No specs are given on either wiper or heater for 41 but heater amperage was mentioned for later models and those were 20 amp fuses on 6v cars. A 12v fuse is fine. As to the wiper, it has a built in circuit breaker so you would only be protecting a short distance of wire if you added a fuse. If you do add one, I would start with a 20 amp. I have no idea of the current draw if the wipers bogged down so that may not be enough.

Someone else will have to say the difficulties on dropping that tank. I know it is not the most pleasant of chores on later models.
