Starter Help

Here is my problem guys, the purple wire that goes to the S terminal on the solenoid is supposed to have 12 volts in the start position,right? Im only getting about 8 volts. Im assuming the ignition switch is bad ? Is there a trick to get the bezel off,it unscrews,butt wont come off!!! Any suggestions?? 67 by the way.

Re: Starter Help

Ray is correct. With key in ignition, push a paper clip into the little hole, push hard inwards, and continue unscrewing CCW the key and tumbler should unscrew out of socket.
Then the bezel nut will come off and switch will fall back into dash.
Youy can un-swage the back of the ign switch, do this over a pie pan, baking pan because of springs inside and other small parts. You can use emery paper and sand the contacts, reassemble, and re-swage the housing and reinstall the switch.

However, check/clean all connections, battery clamps, battery junction block, horn relay buss bar, and check for broken strands at the factory crimp under the dash. The red wire splits to headlamp switch and ignition switch. also check ground cable/wires for their clean connection.

Remove all the other variables before doing the ign switch.

Re: Starter Help

you have voltage drop at starter you should om the wire or check volts before the neutral safety switch. old harness build up resist causing low volts

Re: Starter Help

No neutral safety switch. Forgot about my Chiltons book,got it out, getting good voltage at the 12 volt terminal,but not coming out on the purple wire! Have to check a few other things, but I think its the switch. Good voltage everywhere else,junction block ,horn relay and every other place I checked. need to check horn relay connections,but has good voltage there!!

Re: Starter Help

You might take the time to check the voltage at the points mentioned as they could have resistance and giving up the voltage as heat at said points. No load, you will read battery voltage. Place it under load and measure just to be sure no voltage drop at any connection.

Re: Starter Help

Cant check under load because solenoid is just clicking. Brand new solenoid and starter checked out good too! New battery too,butt think Im going to take it back to be load tested too!

Re: Starter Help

Nice ride!
Use a remote starter switch or screwdriver across the solenoid terminals as this test will tell you if it is the ign sw control path or a faulty battery.
And you may as well place battery on an external charge, slow one would be nice, all day long.

Re: Starter Help

that purple wire wouldnt be tapped into the cloth covered wire that goes to the coil would it? Maybe previous owner redid wires in a wierd way. that cloth covered wire is a resistance wire with lower voltage. just an idea of something to do, follow that purple wire all the way from starter to fuse panel.

Re: Starter Help

Don't forget the ground side. Ground the block at for example a bolt hole next to the timing cover.
Does the starter turn well jumping from the battery + side to the Sol S terminal?
Chances are good there are several small resistive connection points between the battery and the S terminal. Trace from the battery along the low current side all the way to the solenoid and clean each possible.

If the solenoid clicks, its probably a low current problem.
If the starter motor turns slowly, its a high current problem.
If the starter freewheels that's another issue.

The point is to narrow the search...
