1960 Impala..just won't start

Hello there everyone,

glad i found this page online and i'm really hoping i can find some help with my problem

My brother and i bought a 1960 impala at the daytona turkey run and had it shipped to germany.
upon arrival in rotterdam the car would not turn over. we assumed it was a dead battery - nope -
a bad fuse - nope -
bad ground - nope -

we towed the car back to our shop in kaiserslautern germany to take a closer look - but haven't been able to find the problem.

the battery is fully charged but the engine won't crank ??
we tried shorting the solenoid (violet wire ) and the car will turn over but won't fire.

we've checked the ground straps, and fuses

funny enough the interior light, headlights and voltmeter work - everything else is pretty much dead.

i found this wiring diagram online http://chevy.oldcarmanualproject.com...mages/60v8.jpg

but haven't been able to locate the problem.

is the dark green wire that runs to the solenoid 12v off the ignition switch ??

any great ideas out there ??

no starting

your having the same problem as another poster here.. ok, with 2 people, have one turn the key to start, ck for voltage at the S on the starter. none? ck neutral safety sw... have 12v then at the same time (key to start) ck for 12v at the R position on the started. that 12v is the by-pass for the ballast resistor. make sure the points aren't rusted together too. if its turning over and not starting?? pull the dist cap and turn over till the points are closed.. now just turn key to on and with a small screw driver open the points and close them, you'll see a small spark... hopefully..don't touch the screw drive to an ground while doing this, you'll defeat the purpose.. bill

Hope you've got a 12v test lamp. It will make things easier. Test the voltage at the positive terminal of the coil with the key at "on" and also while someone is holding the key in the "start" position. Sounds like you may have a bad ignition switch.

thanx for the replies guys

just got back from the shop ....we messured 12 volts on the positive side of the coil with the ignition on but when the key is turned to start the engine it drops to 0v ???

we also removed the ignition switch and everything seems to be ok.
is it normal to loose accessory power when the key is turned to start the engine ?

The wiring on the selenoid checks out ok. are there any additional fuses or fuse-links in the wiring harness?

hope to hear from u

thanx

tom & dave

When the ignition switch is in the start position the solenoid activates and does (3) things.
1- connects the battery main cable to the starter motor.
2- engages the pinion gear to the flywheel ring gear.
3- connects a by-pass wire from the main battery cable to the coil + terminal.

If you don't have full battery voltage during cranking check to see if there is a dark green (original color) wire running from the solenoid to the coil.
Make sure the coil - terminal is grounded.
The solenoid may be defective.
The switch section of the solenoid may be loose.

might be your resistor wire to the coil..... hook a wire from the pos post of the batt to the pos post of the coil, see if she starts, might have to jerk wire off batt in order to kill it, DO NOT RUN IT HOT WIRED FOR ANY LENGTH OF TIME! couple min max...... it will burn out the coil if you run it hot wired too long

ACCY and ignition circuits drop out during crank on the 59/60 OEM ignition switches.

Must check that purple wire from the ignition switch to the neutral safety switch,
and from the NSS to the bulkhead connector behind the engine
from the bulkhead to the starter.

The circuit from the starter to the coil (R) must be working for the car to start.

If you have 12 at the +coil with the key on----that wire is good, it will drop to zero when cranking if the starter circuit is not working----and car will not start.
That wire will be energized by the starter if the starter circuit is working.
