My friend bought a 53 studibaker with a V8 automatic and he can only start it by jumping the starter solenoid. Is there some trick, or is it just a bad neutral safety switch?

Sounds like a bad (stuck) solenoid. Try giving it a tap with something hard while trying t o start it. -
The first thing i check for is power to the crank wire on the solenoid when trying to crank it..
This tells me if it’s a solenoid issue or a feed issue.3~ Tudor's & 1~ Coupe

Need to look at the wiring schematic, because the solenoid might be wired like the Model A coil and horn are wired.
That is it might have 6 volts and then get the ground through the neutral safety switch.
Need to follow the voltage and the ground path until the fault is found, and that's why it good to have a wiring schematic.
In fact I took my 1950 shop manual to Kinko's and had the wiring chart and the lubrication chart blown up to poster size to hang on the wall.Comment

According to the first diagram we have a starter switch, neutral / reverse switch, and a solenoid. So i'm back to my first post of checking it at the solenoid crank wire first. Depending on what is found there the rest is pretty easy3~ Tudor's & 1~ Coupe

Hand drawn schematics..back when stuff like that was done on a table,with pride..beautiful work.
what is an 'anti creep valve'..I can tell what it does by the name,but how does it work?Comment

That switch sends a signal to the automatic to keep the car from creeping forward until the throttle is slightly pressed.Originally posted by CM2 View Post
The wiring schematic shows overdrive and kick down wires, but I don't see anything for the automatic push button or neutral safety switch.
On the schematic shown, the solenoid has full time power, and gets the ground from the starter switch mounted under the clutch pedal.
I'll see if I have something on the automatic.
BTW Studebaker came out with the Borg Warner automatic during the 1950 Model year, and Ford wanted to buy rights to use it. It was a mistake for Studebaker to not sell rights to Ford, as it could sure have helped them (Studebaker) stay in business. This automatic was the first year automatic for Studebaker, and it has a lock up torque converter. That's why I just laughed when cars of the 80's were bragging about the new lock up converter for better fuel economy.Comment

My '53 Commander Coupe, with Standard Transmission, had a Factory Installed, spring loaded toggle switch in the dash, to operate the STARTER!
It also had a nifty HILL HOLDER System, for the Brakes!!!
Wish I still had it, that dude would FLY, with a Dad Installed, 322 Buick Nail Head, out of a TOTALED Highway Patrol Car !
With its' Light Weight, fabulous AERODYNAMICS & Overdrive, it was a LETHAL open road machine. The car lost 140 Lbs weight, after switching the Stude V-8, for the Buick V-8.

I believe you're right about it being hydraulic lock up. I have a Studebaker shop manual on the automatic, but can't find it right now.Originally posted by Mitch View Post
The small terminal on the starter solenoid send the ground to engage the solenoid, so when you say "jump the solenoid", do you mean you ground this terminal, or do you use a heavy cable to jump the two large terminals?
If the starter works when you ground the small terminal, then go to the neutral safety switch, and see if it starts when you jump those terminals and push the starter button. It also might only need to be adjusted.

Due to mobility problems requiring me to wear braces on both legs I had to modify my 1930 Town Sedan, I want to keep the car as stock as possible but I am determined to drive it ,this requires me to modify it within reason keeping replaced parts so it could be put back to original someday. Because I couldn't depress the starter rod on the floor I removed it along with the starter switch on the top...04-19-2018, 09:39 AM -
When making electrical checks you can be measuring voltage or amperage. Voltage is the pressure behind the electron flow. Think of a high pressure hose squirting water on the lawn. It might have 40 pounds of line pressure, but not a lot of flow. Amperage is the amount of flow. Think of a river which flows hundreds of gallons of water per second. It doesn't have much pressure, as you can hold the open...05-17-2017, 04:49 PM -
I posted on the regular Model A thread about my "new" car and I wanted some opinions on wiring. First, wiring doesn't scare me. I'm into computers, ham radio, electronics in a big way. I understand electricity and electronics quite well. That is not an issue.

I am under the impression that model t's had starter buttons on the floor board however mine seems to be a small button to the left of the steering wheel, is this something that came standard in the later years or was this an aftermarket part?

I just install a new horn grounding wire on my 1931 truck and when I go to place the upper and lower halves together the lights turn on and when I slip the switch on the steering column, the horn sounds. Is there a small insulator supposed to be on the light switch button? I think the former owner had a piece of tape wrapped around the button only exposing the top of the button. Any help would be...Starts03-24-2018Ends03-26-201803-25-2018, 06:30 PM -
One of our club members just acquired a rather sharp '49 Ford and has run into a problem replacing the dash lights. When he touches a wire the cloth coating evaporates and he is left with a bare wire.
Any of you out there in interweb space have anything he can possibly coat the wire with that will keep the cloth in tact while he changes the bulbs.
I was thinking maybe some...02-03-2018, 11:28 AM -
Rusty i having a hard time starting but once started runs great! I thought it might be something draining the battery but it is 6.15 at the battery, starter and coil. It will only want to do a revolution and then sometimes a few. Starter has been rebuilt by a local shop. I put a jumper on the pos ground to a engine bolt to test for bad ground but does the same thing. Head lights and horn are not installed...11-18-2017, 09:32 AM -
For the last few weeks I have been having a small problem with the light switch on the bottom of the steering column and yesterday I decided it was time to attack it.
So, I remove the switch, start to clean it up, and remove the switch plate and disassemble the whole thing. Well, very little oil between the tang plate and insulating plate, but that is all. So, I get out the test light...10-18-2017, 12:39 PM -
I just tuned my Model A last nite and the engine sounded good. Today, it would not start. It turned over good and the battery was strong. I opened the hood and the wire from the starter into the metal channel up to the terminal box had burned thru just 3 inches from the starter switch. I removed all wires from the terminal box and pulled the wire out of the metal channel and all of the insulation...09-05-2018, 10:21 PM -
