how do i disconnect neutral safety switch

i have a 65 chevelle. we converted it from a column shift (originally powerglide) to a floor shift with th350. i am having starting issues (acts like battery is dead) but battery is good. thinking it could be neutral safety switch in column (volt guage drops to 0 when turned to start) otherwise at 13-14 volts.

can anyone tell me how to find and disconnect the neutral safety switch

hoping that this is the problem. please help

It is the purple wires on the top of the steering column, under the dash.
You can make a jumper to test it with,doesnt sound like your problem but nonetheless . Jumper the 2 purple ones together and there you go.

Your problem is not the neutral safety switch, key being the V meter going to 0. The problem is age old GM of poor contact in the battery lead connection to the large post on the starter, or a poor ground. If your battery is in the trunk and you are running your bat ground to the frame instead of a # 2 wire to the starter mounting bolt, it will have the same symptoms. Having run an auto without a N safety switch for a while, I would never recommend disabling it.

Your new floor shift should have provisions for a NSS, I would extend the purple wires over to the new shifter. That's what I did when I converted from column to floor. Sounds like no big deal bypassing the NSS.......but after you forget and start it in gear and it takes off on ya, you'll see the light and hook it back up.......don't ask me how I know this......lol

Love This Forum

Thanks Guys For The Info. I Love This Forum. I Am Going To Wire The Nss To The New Shifter. Sounds Like I Have A Connection Issue As Well. Battery Is In Stock Position Under Hood And Grounded To The Alternator Bracket Currently. I Will Ground It To The Starter Mounting Bolt As Well.

Could I Also Have A Solenoid Problem? Reading Alot About Heat Soaked Starters/solenoids.

I Am Learning As I Go And Appreciate Any Info That You All Have That Can Help.

Thanks Again

There is a bolt hole on the pass side head, just behind and below the alt (at least my setup) that's a very convenient connection spot.

Key on the column or dash, I don't know to much about the Chevelle. If it is column keyed, do you have a connector of wires (from the column) bolted to the lower end of the column? If you do, that could be part of your porblem..... that is the actual Acc/Run/start switch and it sildes for adjustment. Try unbolting it from the column and use a small tip screw driver slide it to the start position and see if that fixes your problem

If it is dash keyed... disreguard the above

Mine had a few issues with juice...... when I checked the ing switch, it was hacked and spliced beyond belief....... ended up replaceing the main feed wire and undoing 30 years of screw-ups!
